Want more low end? Simply add an optional subwoofer like Roland's new KCW-1. Connections are easy, thanks to the Subwoofer output found on all new KC amps. Now even the most affordable models can sound huge!

Been playing keys in bands since 1967. I finally got tired of the thin watery sound I kept getting out of PAs and other KB/comb amps. The KC line has fixed that problem.

I loved the sound of the KC-550, but hated the bulk. Then I played a KC-350, same sound, but as others have noted in reviews, the single 12" spkr just couldn't carry the frequency range at volume w/o distortion. My choices would be distort, or get lost in the mix.

Then I hit on the idea of using 2 KC-350s in stereo. I took a chance, bought 2, and used the Roland stereo feature to connect them together.

Perfect solution. Yes, its more expensive than one KC-550. And for some reason, the Roland stereo feature is not rated 2x120=240W, more like 180-200W (maybe I should run them in discrete stereo). But I can carry one in each hand (48lbs vs 63 for the 550). I have some flexibility fitting them in the SUV along with keys and PA gear. On a crowded stage, I've got options for positioning. Even with two keys, I never run out of headroom. I have a Hammond XK3c, the synthetic leslie sounds great and, if I use the bass pedal drawbar, I can overpower (and annoy) my bassist. My Yamaha Motif piano, synth, and brass sounds are awesome. I play also play sax and harp, and can run them through the remaining channels, or hook up my old DX7 in channel 3 and split the 4th channel L/R with the sax and harp.

So, I think I've hit on the secret to using this amp and its features very effectively, even if it means buying 2 of them. At least, that's my story and I'm stickin' to it.

Both my brother & I have worked for 20 years in live performance & have used most commercially available keyboard amps. He presently uses the KC-500 and I use the KC-350. This amp is NOT road-worthy and the design is severely lacking. Within three months of normal use we both experienced dead channels, ground problems with the 1/4 & XLR outs to the board, tweeters that don't last, input jacks that short out. As far as design, personally, I would have preferred the controls on the front as the amp is usually raised to ear-level. Individual EQ's per channel would also have been preferred and may they all be 3-band. Two-band is almost useless. The reason I still use this amp is the weight. It is convenient for smaller jobs. I wish there was an alternative in the same weight-class with 4 inputs. Another thing, the smaller Rolands channel 4 cannot be sent to the line-out. Monitoring purposes only??? HEH??!!! Hey Roland,let me decide that and don't deprive me of the output. Yes, I could go with a seperate head and bottom, but that is highly inconvenient when going from room to room in single to band situations.Buy this amp ONLY if weight is an issue and may an alternative arise soon.

    Comments about Roland KC-350 120W Keyboard Combo Amp:

    Works as advertised, powerful enough to keep up with guitar amps and drums. Really good with strings and syns. I use it with a pair of VR 09's both in stereo and it has inputs to accommodate the two quarter inch cables in each channel. Relatively compact and not light, but still manageable for one person to transport. A good step up from a regular guitar or bass amp.

    Great sound with my keyboard, compact. Only downside is that it is heavier than advertised. But fits nicely in the back seat of my small car.

        Comments about Roland KC-350 120W Keyboard Combo Amp:

        The KC350 is the very finest I've used. I'm a keyboardist who does keys and bass (on split keyboard) and sings; this amp delivers all three of these voices beautifully. I do need help in lifting and loading it, but in every way this amp is superior and is ideal for keyboardists.

        Comments about Roland KC-350 120W Keyboard Combo Amp:

        Save your money and get something better than this...I've had to replace the 12" speaker three times in six years...and I only use this as a monitor as I go direct through the main sound system..It should not have blown using it in this capacity...I've had a professional repair person up the wattage and the magnet size to keep from dropping more money into this piece of junk...
        nice setup for multi keyboard players
        not in having to replace the main speaker every two years
        Not worth the money

        By Lynque

        from AZ

        Comments about Roland KC-350 120W Keyboard Combo Amp:

        I have this on loan from a theater company and, now, saving the bucks to buy my own. I do a solo act with tracks and it works perfectly, not the least of which is that my Sho-Bud guitar sounds exactly like it should. The only minus is the lack of reverb, but an Alesis Nanoverb fills in nicely. I haven't figured out the shape control yet, but the 3-band EQ allows a good range to tinker with. Last, it's certainly heavier than a Fender Frontman, but the two rigs are two different musical planets!No doubt, an amp to consider.

        Comments about Roland KC-350 120W Keyboard Combo Amp:

        I use this to run vocals, and guitar and bass modelling processors. In all cases it cuts clean even at high volumes to blast along with a full band with drums at practice. I have no fear of blowing the speaker, and usually only have to turn it up to around 5 to compete with a drummer. It is kind of expensive for the watts, but you get what you pay for. This guys is durable, reliable, and sounds very very clear no matter what signal I put through it. As far as features go, it's pretty basic... just some EQ and this 'shape' button that I don't understand or bother with. I just leave the flat signal and do all my sound shaping in my effect pedals that run into it. Essentially, if this is where your budget is around, this is a good buy. You'll be fine.

        Comments about Roland KC-350 120W Keyboard Combo Amp:

        I had a Peavey KB% prior to owning the Roland KC-350 and the Roland blows the Peavey away with sound quality. The KB% is a stereo amp and higher priced but my KC-350 dosen't "clip" out at higher volumne settings. I use a Kurzweil stage piano throught mine and a Yamaha synth. The only thing better would be to have two of them...so I'm buying another for the stereo effect.

        Comments about Roland KC-350 120W Keyboard Combo Amp:

        I've owned this amp for about 3 months now. At mid to lower volumes it's awesome. You really couldn't ask for more as far as the crisp, clear, and true sounds it replicates. However, when you adjust the volume up past 3/4 full, the amp begins to distort. It's a problem when trying to play an acoustic guitar or keyboard through it. This amp is more than sufficient when used at anything lower than 3/4 volume or singing. I'd recommend getting the next size up if you need it to compete with drums or loud guitars because it's a nuisance having to ask band members to play softer - and who wants to play softer anyway?
