I use this twin pedal with my martin and it has been nothing but great. The sound quality is excellent and the fact you can save presets and switch between them on the fly is a huge plus for me. All of the settings sound great with my acoustic excpet for the "acoustic" setting. The acoustic setting is very tinny and sounds terrible through an acoustic amp or p.a. The ambience knob is actually a very decent reverb, but the brilliance knob sounds equally as bad as the acoustic setting and makes things sound very bright and shrill. The rich and standard settings sound wonderfull though and I wouldn't trade this pedal for any other chorus pedal on the market.

So many options, you are bound to found a sound that works for your needs. The quality of the tone is what puts this pedal a mark above. Problems included the bypass amplitude is smaller than the active channel. And of course, it will be worth the money to buy the adapter as this pedal is a battery hog.

I got this pedal a little while ago. I FREAKIN' LOVE THIS PEDAL. It has awesome chorus and effects to it. It can be used for anything. One problem is that the twin series boss pedals tend to burn up batteries like its gasoline. You spend a lot of money in batteries, so you should get the power adapter.

other than that, you can make any sound imagineable. there is more features then you could ever need.

I compared this pedal (BOSS CE-20 Chorus Pedal) with the boss compact pedals (BOSS CE-5/CE-1). Before trying them, I wasn't sure the extra cost would be justified until I heard the CE-20. I play an Ibanez electric-acoustic, and the difference in tone I could get out of this pedal was amazing. I compared this side by side with the Boss CE-5, and this pedal really just sounded so much richer, especially on the "acoustic" setting. There simply wasn't any comparison. Another thing that's really great if you plan on playing live is the fact you can set up 5 presets. For me, that was the tipping point - I get incredible sound, and I can use 5 different presets that are footswitch selectable, which really helps when I play - sometimes I'm playing acoustic solo's, which need one setting, and when playing with the band we have lots of different sounds we emulate, so being able to switch is a huge help. I am very satisfied. If you are thinking of getting one of the compact boss chorus pedals (CE-1/CE-5), I would recommend you first listen to this one - once you do, I think you'll end up buying the CE-20.

first off, i play the bass, and i am extremely picky when it comes to my tone and how my effects mess with it. when i turned it on and tweaked it, all i was able to do was say "wow." amazing pedal. ran it side-by-side with the BOSS CEB-3 Bass Chorus, and the CE-20 did everything the CEB-3 could do, but better, with more versatility, and AMAZING QUALITY IN TONE! the low and high knobs as well as the brilliance and ambiance knobs add so much more flavor to whatever it is you need. i almost want to keep it on the entire time because the sound is just beautiful. worth more than every penny.
