The perfect combination of power and value, the Roland KC-350 is ideal for medium-sized gigs. The Roland KC-350 features a 120-watt amplifier with convenient 3-band EQ, new Output Select and Shape switch features, plus a Subwoofer output for extra low end. The Roland KC-350 can also be connected to mixing consoles via its 1/4" phone Line output.

The Roland KC-350 include Roland's Stereo Link feature for chaining two amplifiers. Using a single cable, you can connect two KC amps for true stereo sound while controlling them both from the amp nearest you on stage.

Thank you Roland!

Awesome amp!!

Sounds great at any volume..Plenty of power...It's not light but at 48lbs it can moved around for rehearsals without too much trouble, wouldn't be comfortable with anything heavier.

Roland KC350

I have a typical size band room , I recently got the Roland KC350 & hooked it up to my synthesizer , the sound quality is awesome & I barely have the master volume touched. It truly has brought me to a new level.

Very nice amp for keyboards.

I purchased this amp from Jon Gauthier at Sweetwater. I am using the Roland VK-8M Organ Module with a Motion Sound Pro-3 Rotating horn along with two Edirol M-80 controllers for my Organ sound.(Also purchased from Jon G. at Sweetwater). I use the Roland KC-350 amp as the low rotor simulator. It sounds GREAT !!!!!!!Has a very nice Clear low end. SWEETWATER ROCKS !!!!!
Music background: Have played keyboards for 50+ years. Professionally for 35+.

Fantastic amp

For those of you who are looking for an amp to cover a wide range of instruments, this amp is the king for me. I have a modeling guitar effects pedal (w/ guitar), bass guitar, keyboards, electronic drum kit and an ipod. Each one is able to be connected (at the same time) with great sound. I was, at first, worried about not having two speakers for a stereo feeling. This amp with the ipod alone was able to produce a huge sound just on level 2 out of 10. Since I have multiple instruments, this amp is perfect. At the store I tested the bass quality with a really cheap bass and it was full of tone. A guitar through a model pedal is great too. This amp is basically a monitor/pa system. If you are considering buying it, spend the money. You will be happy. This is my guitar amp, my bass amp, my electronic drum monitor and when I have a party in or outdoors this is my PA system. Without a doubt, a great purchase.

Sweetwater Advice

Kenny Bergle

Man, I'd buy one of these if my original Roland KC-300 (predecessor of the KC-350) didn't still work so well! The new KC-350 is even more powerful and has a smoother repsone than the KC-300 AND it's less expensive. Now, that's progress!

Jeff Hollman

Roland has long been making the clearest, loudest, and most useful keyboard amps in the industry. It's rare that I sell any other keyboard amp in the KC-350's price range.
