This pedal works great for my bass rig

This pedal works great for my bass rig, the best part is the volume/ expression pedal options. Great pedal for someone who uses a lot of effects!

Ive had this pedal for a couple months now and its rad. Tons of features! Im using it for live loops on the fly (nothing prerecorded) so I really bought this for the finish feature, where when you stop the loop, it plays until the end of the recording, then stops.

Helpful tip: if you use a foot switch in the Ctrl In, the loop will not play when you clear it. They recommend a certain footswitch in the manual but Im just using a plastic keyboard sustain pedal that I got at Goodwill for like five bucks

I got this pedal because my guitar is active, and I was using both the magnetic and piezo outputs separately. (I read that a high impedance volume pedal could suck your tone if your output is low impedance.) I have only used it to silence the instrument while tuning or unplugging cables so that the sound man does not kill me. It is not a big deal, but I am docking it only one star because a little bit of sound gets through when the heel is all the way down. I did not want to use the side output for a tuner, so I fixed that output to zero with a small piece of masking tape. Some people have complained about its light plastic construction, but this has not bothered me. I have not tried to remove the feet yet, but I will eventually put it on a pedal board to use with another guitar with a preamp.

This pedal works with my Yamaha keyboard and my Roland electronic piano.  All I had to do was flip the switch on the bottom.  The pedal is heavy, so it does not slide.  It is also well sized for the foot--not too small.  Feels like a real sustain pedal!  You can't beat the price either.  I recommend!

I needed to add some traditional bluesy or 70's/80's rock crunch to my DI setup for church. This pedal provides plenty of that for my needs.

find some youtube videos on this pedal. It has lots of flexibility in tone shaping.
It provides the sound for a good price. I'm not hung up on brand so I'm happy with the Behringer pedal.

This is a great little pedal; I use it with my bass.  It provides a rich, lush, chorus effect with leslie-style vibe.  This little guy is going to live in my gig bag. I should add that I have experienced none of the signal noise mentioned in one or two of the other reviews.

Hinestly, if you only had this one pedal for your bass, you wouldn't really NEED anything else (unless you'd like something else). I've played plenty of gigs where I go to set up my board but one pedal doesn't work, I lend my distortion to a buddy, Bla bka Bla. And I literally just use the sans amp and my rig sounds amazing. Best musical investment I've ever made. I will NEVER get rid of this pedal. I will be dead and buried with this thing!

I was worried about my tone being colored and that this may break as it isn't metal. Have had if for some time now without issues. It does color the tone slightly, but who's to say you wouldn't mind the slight variance in tone that happens? It is hardly noticeable and when my tube amp is cranking, you really don't care to notice. I use it for doubling, harmonies, and dives. I have played "Killing in the Name of" with it but it lacks that expression pedal feel and smoothness. I think you can get an expression pedal to hook up to it, not sure, I'm not interested in one. I got it because I needed it to do the aforementioned things and take up little space on my board. I am not disappointed with the purchase. It does have small, hard to read, especially on stage, writing and you can't pre-program it and save settings, but for $50 it does the job and has held strong for the months I've used it.
To qualify it's existence among my pedals and show I'm not the kid in the bedroom, this is on my PedalTrain board with; Line 6 Relay 30 Wireless, Dunlop Q95 Wah, TC Helicon Polytune, TC Electronic Dreamscape, ISP Decimator G String, TC Electronic Flashback Delay, TC Helicon HOF Reverb. Into Peavey 3120 Head and 5150 Slant Cab. I use all Monster 500, Monster Rock, and Mogami Cables. My opinion is the slight tone coloring is negligible compared to the amount of useful effects you can gain in one small footprint!

I put this pedal right after my guitar to kick up my overdrive (Analogman Ibanez TS-9 Silver) while running through 38ft of cable before getting to my amp instead of after my drive pedals as a clean boost. It undoubtedly thickens my guitar signal and creates a smooth, fat, and clear overdrive without me having to turn up the "Drive" knob on my TS-9 pedal. Before I had the RC Booster, turning the "Drive" up on my TS-9 gave me too much drive toward distortion. It truly pumps up my signal from my guitar's pickups dramatically increasing sustain and tone. I can also turn the TS-9 off and have a fat clean tone that can be heard in the mix. In the past I lost too much oomph to play clean after turning off the TS-9. I now have the tone I've been searching for. Makes my mouth water like a great steak!

I just got this gadget yesterday & I can already say this is a great pedal. I have in the past been somewhat ho-hum about Boss gear because I have often found that other companies simply do a better job but in this case I must say this is a spectacular gadget. BTW, to correct another review, this pedal does not do "sound on sound", you can only record a single loop & you cannot overdub. On that note, I will say it would have been nice to have a longer looping time but then most people if they are in to looping will have a dedicated looper so this is not really a big issue. The loop time is long enough to record short bits to play against & also to really get a feel for what this pedal can do.
On a really great note, I did sync this pedal to my computer running CUBASE & it performed flawlessly. I tried several things to get it to loose sync & it just kept right on ticking. ( Yes.the pun is intended ) The sync was a big concern for me & now it isn't.
The overall sound of this pedal is very much dependent on the sound you feed it. Very much like my EHX HOG, the results of what goes in does not necessarily go out can be surprising. Starting out with a really ugly guitar sound going in can produce a gem on the way out. Kind of a Pygmalion experience.
I write a lot of space music & this thing has already found it's way in that work. One real problem with this pedal is that until you get a chance to play with it you simply cannot appreciate all the nice results. For discovering new FX textures, this is a Boss pedal I cannot recommend highly enough.

This pedal is great!  Having a boost and an overdrive in 1 pedal is just what I needed.  I have tube amps that sound good and this overdrive really sounds good with them.  The neat thing about this pedal is if you have to play through a solid state amp, you can set the overdrive up for a good sound for rhythm then kick on the boost for a lead.  Works great, I'd recommend it to anyone

Good 80's style hair metal distortion.  When you turn up the gain, you get a thick, crunchy distortion that works well with either single or double coil pickups.  This pedal really shines at the low gain settings, however.  Dial back the gain and this pedal works great at low to moderate distortion...almost like an overdrive pedal.  The high gain is ok, but I find myself using this a lower gain pedal more often.  Your mileage may vary.  As with all musical items, it is subjective.  It is a little bit bulky and takes up significant space on a pedal board.  Also, the input and output are on the top of the unit and not on the sides.  The 9v input is different than the normal Boss style that most pedals use and will require a different adapter.  For these issues, I knocked off one star.  This thing is just built awkwardly in terms of size and setup.  Sounds great though.

Very good pedal - While I don't believe it sounds exactly like a "Marshall" it has some of that character and it IS a GOOD sounding pedal -  I use it for live performances along with a compressor and few effect pedals (rev, dely, mod) and it works really well.  I don't like the heavy drive settings at all and it can get noisy at higher gain and/or with VOICE control (as you turn it clock wise) - I like it for adding charcater/punch to my live rig - the tone controls allow you to make quick changes just as if you had an amp and I can now just plug into a board and use monitors instead of lugging my amps.  I also have the "American" model for which my review is identical to this one.  They are BOTH very good pedals and great tone shaping tools.

Great unit overall.

Works great, however you should run a powered pedal in front to avoid tone loss on guitar/bass.  Also, this has an exponential potentiometer controlling the volume so it is very sensitive.  There is supposed to be a taper switch on this pedal, yet I haven't found it.  Perhaps that may be a newer feature that I don't have.

This board is perfect for me.  I play the bass and occasionally use a few effects.  The Jr. holds the following for me: Bootzilla Wah (this is a very big pedal), DOD A/B box, MXR Flanger, Boss tuner, Boss Bass Overdrive.  This set up pretty much fills the whole board.  I have a standard A/C adapter that plugs into the tuner and then chains off of the tuner to all of the other pedals.  If you have this tuner, then the recommended power options (voodoo labs, dunlop brick, etc.) are unecessary.  Just get the chain cord and you can get all of your playthings fired up.  The plug for the power adapter doesn't fit all that well underneath the board, but it is managable, and much less expensive.  I usually just plug it straight into an outlet or powerstrip away from the board anyway.  The board itself is built like a tank and the case it comes in could withstand a 4 megaton atomic blast in my estimation.  There is some extra space within the case as well, enough for a cord or two and some other miscellaneous small accessories.  I don't attach the power cord to the board, as stated above, and it fits in there nicely with plenty of room to spare.

It's a good pedal. If you are starved for cash, you can live without it, but if you can afford (50$ to 100$) for it, then pull the trigger. I use it at the end of my long pedal chain. I place it on the amp since it's always on, and not on my board. I've tried it in the loop as well as directly before the input and I see no real difference, but that could be my amp. Again, I leave this thing on all the time, and adjust as needed. What I like about it is that it's a quick fix when playing your amp in a different acoustic environment. Instead of having to tweak every parameter on my amp and my pedals, I can simply adjust the two levels on this pedal and fix any problem, as generally the problems I run into when playing a different space is bass/mud and treble/highs. The contours allow you to fine tune these aspects, instead of having to tweak every pedal and amp setting. I can tweak my sound in seconds. Great pedal, well worth the price. I found mine on another site for about $40, so you can't really go wrong. I highly recommend.

I needed a dependable delay pedal with a myriad of sounds to complement my Fender telecaster and Vox amp. I play lead almost every week for two services at our church playing contemporary worship music. I like all of the sounds and features. Digital delays are great but I end up using the analog effect the most. Really glad they included that on this pedal. The reason I gave it 4-stars is because the knobs are too small to manipulate with your foot. It would be nice to adjust on the fly without having to bend over. All in all, though, a great pedal.
