I bought this to record audio in the field as I had no access to a studio. I needed something quick and inexpensive. The box did prevent ambient sound from getting into the recording and the audio worked well enough for the project. However, the sound proof foam was hard to work with because it's too flimsy to stand on its own. The box include a tape like substance for the top edge but it didn't hold the foam. The foam for the side would also fall over. I tried using two-sided tape but it wouldn't stick to the foam. I even tried Gaffer's tape but it also would not stick to the foam. I ended up holding the foam up while the audio was being recorded. In the end it worked fine but dealing with the foam was not fun.Dan B.
Main issue, foam constantly falls and droops. I suppose they could be used in a pinch but they are falling apart from day one. It doesn't even make sense how the foam is supposed to stay in there. Something simple like Velcro or a binder clip could greatly improve the foam attachment.Demetrious
For anyone on a budget, needing sound-proofing to reduce background noise while recording, this portable booth box may be just what you are looking for. I live in an apartment and I have limited space for a recording studio, so my recording facility must be compact. And because I live in an apartment — a studio to be specific — background noise and ambient sound is ever-present. The PSIB27 effectively creates a sound barrier around my MIC, cutting noise substantially. However, this sound-proof box alone, will not eliminate background noise entirely for me and my situation. To further increase noise reduction, I have to use the "noise reduction" feature in either Cool Edit or Audacity — the recording/editing software I use to make my recordings. Of course, if you live in a quieter area or have a room that is better isolated from background noise, the PSIB27 may shield background noise even more … maybe even 90 to 100 percent. But I will not make the claim that this item will absolutely eliminate your background noise. Your results, like mine, will vary. However, for the price and compact, space-saving design, I am satisfied with the results I have achieved, using the PSIB27.ifthepriceisright

This does the job it's supposed to do. I used it for home practice, and for stage monitoring, with a PodGo, a Helix LT, and my friends Headrush floor unit. I've also used it to monitor when I recorded via the PodGo to a PC. The sound is good across the volume range, including for playing quietly at home levels during the day or evening. I'd still recommend good cans though if you plan to play at 2am and share a wall with a neighbor. It also handled stage monitoring exceptionally, with a live acoustic uncaged drummer, a bass player using a Harte head and 4×10, and a piano player who seems to think that the object of the game is to drive the keys into the floor. Oh… and a sax next to me honking like a flock of geese. No issue hearing myself, and it reproduced the signal with full integrity to the house speakers. A quick tip… do not sit it on a carpeted surface. I did notice that this greatly changes the sound. I have it in a monitor cradle on stage and on an amp stand at home and it works great. Just a heads up. In summation, a great solution for the average player.MadProfMisal
Overall: If only I had known about these the day they came out!. To be fair, I've been attempting to find the Holy Grail …er, perfect marriage between my quality floor modelers loaded with my custom,personal patches to ACCURATELY reproduce what I have programmed into the floor rigs. Big amps,stay home! I have 1×10" cabs,2×12" cabs,4×10" cabs,sealed choices,all kinds of speakers. I am blessed, except they ALL colour my GT-1 hand-tweaked patches/presets in live situations. I can dial 'em in, but need a recovery period from ear frequency overload and load in/outs.Enter the HeadRush FRFR-08 powered cabs,exactly what I wanted and needed.Sheesh, they make all my floor modelers sound like they do when I record via USB,stereo 1'4" cables,and even send a line out to PA or mixer! You can run through guitar amps but you'll get the phasing issue pronto.Look, I have been playing live gigs since 1981,non-stop. I play Gibson,Fenders,PRS,Ibanez big $ rigs,and will not compromise my tone. I'm too old to now, mofos! It's just all the skate slams n such have made lugging gear a real task. These 108's even work for stereo tops and a sub, a studio level wedge monitor,etc.We have recently purchased another set of the 108 and 112's, and that's in the middle of all this C-19. WE have survived by downsizing/adjusting,like everyone else. Thanks zZounds. Quality gear,small footprints,etc for DJ OR our bands gigs(excellent drum monitors,btw) These are perfection. Call zZounds, they know more than me but WOWZA,these make great gtr amps!Please trust the value of these! I take at least one to…everywhere!
Sound: These meet a lot of needs, are tough as Texas women,and sound GREAT. Features: Loved the XLR in's n out,w Line out to board and quality IEC plug/cable Ease of Use: Perfectly tuned nut has options! Quality: Beautiful and functional both! Value: Yes,but I was supposed to get a scratch and dent savings but didn't . THAT SUCKED Manufacturer Support: no The Wow Factor: It fits a niche Overall: We have pair of the 12" and their flat response and quality build have gave our prized floor modeler's a whole nuther' lease in the studio,the road,and @ home. We grabbed a set of the 8" cabs for a BOSS GT-1 stereo rig and they just nail it,every time. HeadRush rule, regarding these flat response cabs at these rates. I'd prefer a $1,500+ powered cab but the FRFR can't be beat until you DO pay that much.Another mind-blowing thing is they work so damn well as a second A/B set of recording studio monitors,it's caused us to reconsider our current set primaries. Kinda hurt but can't complain at the HeadRush vale.Oh, and the work perfect as tops of 10" or 12" sub. 3-wqay PA setups.These are value workhorses that will make your Kemnper Profiler sound as good as ever, your cheap Zoom like studio grade, and compliment our BOSS and Katana gear as good as our High$ PA cabs.ARGGGHHH, wish we would have known all this sooner, but hey, we are finally satisfied,Hombre's.
4. Isoacoustics: Stage 1 Board & Isolators Combo Isolation Board
Product Details:
The new stage 1 board is a portable isolation platform that decouples guitar/bass amps, stage monitors and subwoofers from the stage to provide a consistent sound with improved sound clarity and bass punch. the built-in isolators manage the energy of the speaker to reduce vibrations resonating through the supporting surface to eliminate dissonant sounds in the listening area or joining rooms. the isolators also reduce internal reflections off the supporting surface to eliminate smear and provide greater sound clarity. this portable solution will provide consistency in studio, at home and from one stage to the next. the new stage 1 board includes grip tape which can be used to provide a stronger connection between the amp and the board. use the stage 1 isolators in the studio when tracking to capture that tight open sound, or at home to give your neighbor’s a break from the bass booming through the structure. with built-in isolators, the new stage 1 board is a single unit that offers the same benefits as the previous stage 1 board when combined with the stage 1 isolators (sold separately).

Early days yet, hence only 4 stars: I need to use it in more varied situations to fully assess it. I bought it to counteract boominess from my bass rig when playing on suspended floors, like the typical wooden stage you get in village halls and theatres. I have used it at one band rehearsal on a suspended wooden stage and it certainly helped reduce some of the boom. It would be asking a lot of a wooden plank with some foam stuck on it to completely eradicate the transfer of vibrations into what is essentially a giant cajon! This baby version is big enough to accommodate an Ashdown RM112 EVO II cabinet, so is going to cope with quite a few modern compact bass and guitar rigs; e.g. Barefaced One10s but maybe not a Blues Junior: check your dimensions carefully.Patrick O.
I have a very large system, although it can be broken down to create Several smaller and lighter(!) setups. It has amazed me that the clarity of the system is so for increased. I tested the setup with 3 basses- A Kiesel 6 string accelerator with Eliixir .032-.130 nickels, An Ibanez Btb7 Limited(gold, high gloss, 7 piece neck) Kalium .082-.266 hybrid strings, And aa Ibanez Srff806 with Kalium hybrid strings .102-.266 .The clarity Of the strings is outstanding , especially the larger strings. My setup is like this : Odyssey 18 u case, Line 6 relay 90 wireless, Korg pitch black tuner, Dbx 266 compressor, Bbe processor, Dbx 120a synthesizer,, Behringer Bass ProAmp, Carvin Ac120s , 2 Carvin B2000 Bass Amps each powering a Carvin 8×10 and 2 Carvin 1×18 and the other B2000 connecting to 3 Pjb C4 and a Peavey 2×10. I am still amazed at the difference.
Having read a lot of online hype about the benefits of a Gramma pad I have to admit to being somewhat sceptical of some of the claims but when I saw that PMT had the baby Gramma for £35, significantly cheaper than anywhere else I could find online, I thought I'd give it a go. The Baby Gramma is 15 inches (38 cm) square which is the perfect fit for my Barefaced Two10 bass cab when playing it stood up vertically. My first use was on a gig with a wooden stage, which are a bass players enemy as they cause a ton of boom from bass cabs. But I slid the Baby Gramma under the cab which acoustically decouples the cab from the floor (so the internet tells me!) and the boom had gone. My cab sounded deeper and clearer than it ever had before and I wasn't having to fight any low end resonance for the entire gig. None! Who'd have thought some MDF with a carpet tile glued on plus a bit of foam underneath would make more of a dramatic affect on my bass tone than a new bass, amp, pedal or pickups would??? But it does. It really does. If you don't believe me, and I say that as someone who thought it was all hyperbole for years, then try it for yourself. I've no idea how long it will last as it is essentially a block of foam (albeit a dense acoustic dampening foam) with an MDF top but I look after my gear so I'd hope for a good few years use from it.Sid N.

Overall: What can I say, this thing saved my guitar tone. I can crack my all tube output and capture 100 percent tone now. Before I was always worried about not only that but im recording in a townhouse there is nowhere in my place i could isolate the amp even if it wouldn't bother gf or neighbors. This thing is awesome i bought a 4 dollar goose neck for the mic inside threw in a shure sm57 and just listen through my monitors or headphone, Finally i've got the perfect tone always waiting for me. I run the sm57 into a chandler tg2 and into the computer, the front end is a digitech 2101 into a bogner line 6 spider amp. awesomeness !! Ive heard people say these are to boxy sounding and I don't agree, with an eq handy and some good pres and guitar effects your set to go it sounds awesome.Nathen
You'll notice in photos that the sound deadening is gray and fibrous. The one I received from AMS is upgraded with the egg crate type acoustic foam. This is one step in upgrading the cabinet that I don't have to do, now. There is still no foam at the bottom of the cabinet, which is fine. It can be added easily. Some upgrade with another gooseneck, but I found a way around that in buying an MXL DX-2 microphone. It has two capsules built in that you can use either side of or blend together, but still use the single gooseneck and output. The cabinet uses a Celestion Vintage 30 at 8ohms. It is not dead quiet, but at a decent level it be low enough to not upset your neighbors at all. I would not recommend turning your tube amp up to 10, but you an turn up a 100 watt head at 2-3 and get a nice overall sound. You just need enough of the speaker moving. Very happy with the product.
Picked one up to do recording. Sounds great. Reduces volume so I don't drive the neighbors crazy. Yes the hinges rattle but that does not effect the recording sound so far. May I will try some duct tape. The mic holder is pretty much stationary. But it just a straight mic stand section. So you could use any mic stand accessories. I added 5 – 12" x 12" acoustic foam squares under the speaker to tighten up the sound a bit. It has rubber feet on the bottom so no vibration into floor and it does not scoot around. I am pleased with my purchase. I bought this as a scratch and dent The hinge screws stripped out. I replaced them with larger diameter 3/4" long scre s and they are very sturdy now. I recorded with this in my hallway, and I was using my monitors. No sound from monitor bled into recording. And I cranked the amp pretty loud, but the volume was nowhere near annoying with the lid closed. I recommend this iso cab. 30w vintage delection.Spoiled dog studios

This is a basic no frills DI box. Nothing fancy here, but gets the job done well. I have bought many Pyle products and never had any issues. I know sometimes they get a bad rep because quality control will let a dud through every once in awhile. As for me, I have been lucky, I own several of these DI boxes and never once had an issue. Since they are so cheap I have extra just in case one was to malfunction. You can't build one of these for less than 10 dollars so what do you have to lose.Greg
The Pyle parent company, SoundAround USA (http://www.soundaroundusa.com/) knows that thousands, if not tens of thousands, of the recent version of this direct box are totally unusable out of the box. I recently ordered four of them… and all four were defective. I sought four replacements from the retailer… and all four replacements they sent me had the same defect. I appealed to the SoundAround company itself, clearly explaining the 100% defect, and they sent me four more replacements… and all four of them had the SAME DEFECT. If you look through some of the dissatisfied reviews here, you'll see exactly what the problem is: units manufactured in China (says "Made in China" in big print across the side) have loose/sloppy attenuator switches. There is no way to tighten them up, and solid contact inside is impossible to achieve. So there is either a noisy signal or no signal at all. Let this be your warning – this direct box is bad news. I have two older ones that work fine, but the newer ones are absolute junk! It's a shame the company chooses to pretend they aren't fully aware of what is going on, (and possibly illegal).thirty3na3rd3
This product, Pyle-Pro PDC21 Instrument To Balanced and Unbalanced audio lines, is the third one that I use as an interface between my Behringer MX-1604A mixer output to a Ham Radio transceiver Yaesu, Kenwood, or Icom microphone input, via a Heil CC-1 XLR Y-BAL Cable or generic cable. In this type of configuration, the Pyle-Pro PDC21, as an interface box, ensures impedance matching and hum reduction, with it's Ground Loop Lift circuitry. It's a cheap way to achieve excellent audio transfer.thundergod4u2

9. Monoprice, Sound Block Passive Direct Box With Ground Lift And Attenuator
Product Details:
Throw the sound block in a bag, trunk, or anywhere cable and misc. audio supplies are stored. the heavy-duty construction and passive electronics make the sound block nearly indestructible. this direct interface is extremely versatile as a lo to hi-z transformer for electric instruments and devices to xlr mic inputs or as lo-hi-z to use a microphone with a guitar amp (not recommended only because guitar amps make terrible pas). high level outputs from active instruments and even speaker outputs are not a problem when using the -20 or -40 db attenuator switch. the sound block is a very easy to use passive device. simply plug your 1/4 output from a guitar or electric piano, plug an xlr cable into your mixers channel input, and youre done. a ground lift is provided for use in older buildings with janky wiring or if circuits are different from stage to where the sound system is located.

Nice box for the price. When running pink noise frequency specs, I found that in the -20Db pad position, there is a significant roll off of low frequencies, similar to a good ?low cut filter?. All frequencies were relatively flat in the 0Db and -40Db position. Other than this, the construction is good and does the job as expected, especially for the price.John
The XLR output made my guitar sound strange. The ground lift did little to eliminate noise. I tried a different brand DI box and ground lift removed most (if not all) noise. The XLR audio sounded better too. Because the reviews for this product are high, I can only assume I have a defective unit. I will return this product for a refund.M.
Picked up this DI Box out of desperation as our studio box broke. Definitely amazed by the build quality and functionality. You can't compare this with Radial or any other massive brand but this will get the job done right. Pros: – Cost – Works as expected – Attenuation switch – Ground Lift Cons: – Does not make my coffee Not much of a con but more wishful thinking. This little box is definitely worth getting a couple when in a pinch.D.Y.W.

Overall: Recently purchased another keyboard, and was going to purchase another Radial Pro-D2 which I had been using for over a year, love that box! But, I decided to purchase the JDI Stereo. I did a test with the two and yes the JDI Stereo had a slightly better sound, it was subtle, but it was noticeable in the lower and upper registers of the keyboard (88 keys). Radial products are not cheap, but there is no doubting the quality of these units.Reginald
I decided on buying the JDI Radial over other high quality direct boxes. I made my choice on other reviews and demo's that I could find. Sweetwater's direct comparison of high end direct boxes is what convinced me that this is the box to get. The sound you get is crazy scary. I use the JDI passive direct box for my active Sting Ray Sterling by Music Man. Amazing quality and sound!Flash With No Cash

This DI box is just great, Passive or Active switch, and sounds warm like the morning sun….quite happy with it.Luis
Very well made. great sound.
Großer Vorteil: aktiv und passiv zu betreiben. Hohe Eingangsimpedanz hält den Höhenverlust in Schach. Frequenzband gefühlt sehr neutral und sehr direkt. Im Vergleich zur RNDI rauscht es im aktiven Betrieb ein bisschen mehr (alles rauscht mehr als Neve). Dafür finde ich den richtigen Pegel für Ampsims leichter einzustellen und es fühlt sich beim Spielen ein bisschen natürlicher an. Ich glaube, die Transienten sind auf der einen Seite etwas besser integriert, aber zum Beispiel bei Palm Mutes drückt es mehr. Ich würde also nicht sagen, dass hier die Dynamik leidet. Die RNDI im Vergleich klingt fetter/runder, das ist aber für meinen Geschmack mit etwas übertriebenen Tiefmitten erkauft. Die WA klingt klarer und hat ein bisschen mehr Biss. Wir sprechen hier aber von Nuancen. Wenn ich nicht direkt hin und her schalte, kann ich keinen Unterschied feststellen.

It is built like a tank and does what it is designed to do.drumaddicts
Zeer goede bouw kwaliteit, doet wat het moet doen.
Om een professioneel XLR signaal op een consumenten installatie (opname apparaat) aan te sluiten, is dit apparaat perfect. Ik gebruik de Radial Iso wekelijks voor het terugbrengen van de signaalsterkte van mixer naar een laptop voor audio streaming (via een presonus ione). Waar attenuators nog wel eens vreemd geluid laten horen, is dat hier niet het geval; door de interne trafo's is het geluid prima van kwaliteit en sterkte. Geen ruis en een vervormingen. Daarnaast is het prima te gebruiken om mijn eigen geluidsinstallatie te koppelen aan die van een sporthal. Geluid in de hele sporthal van goede kwaliteit. Kortom, prima apparaat dat elke geluidstechnicus kan gebruiken.

Works perfect, built like a Tank. No hum like the variac I had. Use this with a '68 AB763 silver face drip edge blackline Super Reverb. My line voltage was consistently 125. I drop the voltage to 117 or below. Now I can crank the amp without blowing the 2amp fuse. Would recommend this for all vintage amps. Smooths out my Mark V as well.Ken

Reviews:
As soon as I plug in the guitar, I noticed how clean the signal was. I was able to crank up gain at the preamp without any noticeable increase in the noise floor. The box has a bit of weight to it, giving the impression of a solid build quality and I like the foam at the bottom to prevent slipping on the floor and noise if moved. Really great gear for the price!!!
A great DI is a staple for any live or recording rig. The DI is great to take an unbalanced device like an instrument and balance the device to match it's impedance to a mic preamp on a mixing console, audio interface, etc. Simply using a special cable or adaptor might get the connection right but it won't make the sound right. Samson uses a custom transformer to keep your sound clean and free of distortion. Typically a high impedance unbalanced cable run at longer lengths/using adapters etc will get noise, hum, more interference, capacitance, etc. By converting the signal to a balanced line you can run a longer cable run without degrading your sound. Another great feature is the thru put so you can send a signal straight to an amplifier or monitor without affecting the original audio. It also has a ground lift. So if you're on the market for a high quality reliable mono passive DI box but don't have tons to spend you gotta check out the Samson MD1.Nate M
When I say solid, I mean this Direct Box is built like a tank!! Not only is it extremely durable, the Md1 is also built with great components giving it a broad frequency response with low noise/distortion. It also has a ground/lift switch and is passive so it does not require a battery or phantom power. Don't rely on a venue to have the gear you need anymore! Pick up one of these and know you'll have good, reliable sound from your DI box!!Gerald @ Sam Ash #56

A solid piece of equipment. I have several of these now. BUT, I took a pair of diagonal wire cutters and cut the tip of the attenuation switch off because it would get bumped and switch into -20 db, -40db mode I can still switch it if I ever need to with a pointed object, and even my fingernail will do it.

Reviews:
Sono stato indeciso fino all'ultimo se investire in un torpedo captor o in questo suhr. Alla fine ho optato per il suhr perchè dalle demo su youtube ne preferivo la timbrica, ma sempre con il dubbio:vale la pena spendere la bellezza di 250 euro in più?…però si vive una volta sola e mi sono buttato. Una volta attaccata la mia dual rectifier tutti i dubbi sono svaniti. Il piacere di suonare la propria testata con volumi contenuti e con tutta la versatilità degli impulsi di cassa è impagabile. In più il suhr è grosso, da un senso di solidità e la ventola è molto silenziosa. Se devo affidare la mia testata ad una loadbox, preferisco che sia a prova di bomba. In più il suono e feeling è pazzesco, mai avuti dei suoni così. Consigliatissimo.
Best reactive load box for build and more importantly tone. not all reactive loads are the same!lcuj

Reviews:
As a bass player that uses IEM most of the time on stage the REDDI has been awesome for my live work sound. I have always used a VT Bass to give my bass sound some character to send to the FOH and having the REDDI gives that sound a whole new dimension. I heard the review before that the sound is best defined as having a 3D effect and depth. It is completely true, for the first time ever I don't miss having mic cab or amp on stage with me. The special something that you can only get with a tube are present. I plan to use it fully in the recording studio as well, since that was the original design for it soon. It's expensive yes but it's something that you can't duplicate with any other DI, you need a tube and the 5lb transformer and all the other tech that is in the pedal to be able to achieve that sound.BK-vPD2M
Fat Tube DI. Great for any instrument!!!!Al
I have used the REDDI in live band situations and have recently used it in a professional recording session. The clarity and reproduction were outstanding. I was recording my old stand up German bass and it was the best recording I have ever got out of that bass. The reproduction of the low end was phenomenal the engineer was so impressed that he is going to purchase a REDDI to have for a studio unit. He also said that this was the most outstanding upright bass sound that he has ever recorded. It absolutely rumbled the monitors in the control room and sounded so rich and full in the headphones that if I didn't know better I would have thought I was playing a different instrument. Using the REDDI in a live situation, especially a small venue, it is really nice not to have to lug a big amp around .. just plug in and send a little signal back through the monitors or in ears and that is all I need, and the amount of gain is way plenty for most small to medium sized venues. And if you want an amp on stage you can run through the REDDI and back to the amp and out to the FOH. The up right is my go to instrument but I have also played fretted & fretless electrics and a fretless U-bass through the REDDI and all sound amazing. It is hands down the best bass DI I have ever used. It is a little pricy but well worth the $$ and it is built well with quality parts. Getcha one .. you'll love it!!Stage 5

well made kit and great sound and it looks great
Ich habe mir die Hughes and Kettner Red Box 5 gekauft um mein Trace Elliot Super Tramp Tube Head mit meinem Midas MR 18 zu verbinden, ohne dabei einen Lautsprecher zu benötigen. Wichtig hierbei ist es, dass mein Verstärker keine Röhrenendstufe besitzt. Sobald Endstufenröhren verbaut sind, muss ein Lautsprecher angeschlossen sein, damit der Amp nicht kaputt geht. Es wird jedoch aus klanglichen Aspekten ebenfalls bei einer Transistorendstufe empfohlen einen Lautsprecher anzuschließen. Ich habe dies nicht getan, damit ich über Kopfhörer spielen kann und den Sound im Mischpult habe. Nach ein wenig Einstellarbeiten ist ein sehr gutes Ergebnis raus gekommen. Ich befeure die Red Box 5 via Phantomspannung aus dem Mischpult. Dies funktioniert einwandfrei und erspart Batterie bzw. ein zusätzliches Netzteil. Wenn man die Gebrauchsanweisung liest erspart man sich unter Umständen ein wenig Zeit bei der Einstellung. Nun kann ich meinen alten Trace Elliot wieder brauchbar als zweiten Verstärker nutzen, falls mal ein weiterer Gitarrist mit mir Jammen möchte. Das Gerät ist sehr robust und prima verarbeitet. Für meine Anwendung absolut empfohlen.
Simply effective and a nice interface between my amplifier and computer recording setup. Simple and efficient.chhl

Product Details:
– purchased as a backup. no need to keep it anymore- i'm also adding a big sponge for free.clearsonic ap10 controlling amplified speaker volume on stage or in the studio can be a challenge. amppacs use a combination of csp amp shields and sorber baffles to both deflect and absorb excess speaker volume. the result is lower stage volume and better separation between instruments.35-inch wide x 30-inch deep x 24-inch high amppac 10this small, simple package is great for use on a small amp that is less than 24 inches high. an a1224x4 shield wraps around the front of the cabinet and two s2224 sorber baffles are tacked together with included velcro and placed in a v configuration around the back to reduce the amount of sound bleeding out the back. an s2233 sorber lid can easily be added to reduce overall volume even more (see ap11).parts list:(1) a1224x4(2) s2224
