Roland KC-100

Just fine, would like a mid-range EQ, but there are plenty
of other ways to get that.

I wish it had a mid-range speaker in it, these low-end keyboard
amps are not hi-fi enough for me.

I bought the newer version, the KC-150, at thirty pounds
I can carry it with one hand, no hand-truck needed.

I use piano, strings, and organ sounds, cause I do church work.
I like a lot of bass for stand-alone keyboard parts,
cause I am expected to make up for the lack of a bass player.
This amp is powerful enough to do what I need in the small
venues I play in.
Keyboards (especially piano) need a lot of power
to reproduce the sound properly.

I tried the KC-60 also (store loaned it to me for one gig
because the KC-150 hadn't come in yet), and it's tweeter crackled
when it was over-driven. I backed it down just under that point
and it did fine, but wasn't quite loud enough for what I wanted.
The sound between the KC-60 and the KC-150 is comparable, a litte
better with the 150, but the overall tonality is similar.

If I could lift it with one hand I would get a KC-350,
but at fifty pounds that isn't happening.

Like all portable keyboard amps the sound is so-so compared
to a real hi-fi system, the sound can best be described as "boxy".
I suspect this is because a 12" driver is trying to reproduce
midrange sounds and distorts them, but I don't know for sure.
My board (Roland Juno-D) has EQ on it so I was able
to get it close enough to sound nice but not perfect by any means.
It is still one of the better amps in its class as far as I can tell.

As with its younger brother the KC-60, it does not perform well
when over-driven. I don't care about this, I want clean
sound and am willing to buy as big an amp as necessary
to get clean sound for my needs. When driven within
its limits it does fine.

It is pretty new, manufactured 2005. These are a hugely popular
amp. Don't know how reliable it will be. I don't carry
a backup, but I don't make a living doing this either.
If I did you can bet I would always bring a backup.

Never called them.

Overall rating is higher than the individual ratings because
the price performance of these amps is just fine.

60 watt amp, 12" speaker and tweeter, sub port in the front. 4 inputs, inlcuding XLR or balanced/unbalanced 1/4" on channel one, monitor out.

I use this as an acoustic guitar amp in church. Guitar is an old 1970's Ovation with an old Bill Lawrence Acoustic Guitar Pick Up (All this goes with the Old Guitar player making the music)

I have used misc. reverb units via the aux in/out lines. This amp is very rich in its tone and reponds well to the dynamics of your playing.

I use THICK STRINGS (56-13)so I cut the bass on the amp about -1 notche from flat. Sometimes we put 2 guitars through this and it handles everthing fine. I use a splitter on the line out and feed into the Church sound system. I have use this amp at hotel parties in rooms about 1000 square feet and it gave out plenty of sound.

Never had any problems

Never had to call

I have been playing 35 years and owned many amps. This one is just right. 60 watts does the trick and it is not that heavy to lift (Maybe 25 LBS????)This is the first Roland Amp I have owned. If you play acoustic guitar and are looking for great overall natural tones, then this amp is a great value.

I Thought this amp was pretty well featured fr it's price. The whole stereo set up is a cool idea (tho costly - you gotta buy two!) and 60w for solid state CLEAN sound is pretty low for band work... okay for acoustic/duo/trio stuff, but anyone worth their salt in this industry would know that! As far as that rattle, yeah - it sux, but it can be rectified rather easily. Just tighten 'er up.

Very clean - nice and toppy, and the EQ is pretty responsive. Would be nice to have an EQ per channel, but now we're gettin picky! Okay for vocal, but i still prefer a PA for that.

Haven't had a prob besides the rattle. All my Roland/Boss gear has been pretty reliable - can't think of a problem ever off hand

Despite other's comments, I've never had a problem with queries and stuff from Roland. Only too happy to help. Never had a problem as such with gear, so maybe it'd be different then, but so far, they've been fine.

Great LITTLE amp. And anyone comparing Behringer rubbish should be shot. Behringer have some quality control issues to sort out before with their keyboard amps and some of their PA stuff. Put it this way - I had a bad experience - multiple times

KC-100 60 watt amp, 12" speaker and tweeter, sub port in the front. 4 inputs, inlcuding XLR or balanced/unbalanced 1/4" on channel one, monitor out. I use this amp with an acoustic/electric using a Presonus tube preamp and a TC M-One for reverb. I use it both as a PA or as a monitor as needed. Plenty of power of any acoustic venue, great range.

Problems others have quoted here are easily fixable--if the low end rattles up (as mine did when I bought it), tighten the retaining screws on the back. It's not meant to be distorted as a guitar amp, so you better geta ll your distortion from your preamp or a pedal. Any retard knows you don't try to get distortion from the power stage of a full-range solid state keyboard amp. If the high frequencies are too much for you, you geniuses might try backing off the high EQ a little. If you want distortion and cool effects, go buy a vintage Leslie cabinet. But first and foremost, know what you are looking for in an amp when you buy it.

I use this with an acoustic/electric guitar using a simple setup. I get sounds better than 90% of acoustic guitar amps because I use a decent preamp and have good electronics in the guitar. I've also used it with a guitar synth and it shines. I get tons of clean, non-breaking low end (down to C2) and clear highs. If you know anything about guitar electronics, you will know that 99% of the hype about dedicated "Acoustic" amps is BS. The only reason I give this a 9 is because I have to rely on external units for reverb and feedback killing, which would be nice to have but not totally necessary.

Very sturdy, no problems in hauling it around without a case for 2 years now. Never needed a backup, and for the size and weight, it is so much easier to haul around than most heavy acoustic amps (except the little Trace, which is %$%^^ expensive and has a weak low end).

Never dealt with them--never needed to yet on any Boss or Roland product,

I love this amp and would kill anyone who touched it. I compared this to the Fender Acoustic, SWR, Trace and Crate Acoustic Amps. For the power, range and features, this is the best deal on earth. If you can't play acoustic or play like you scratch your butt, this amp (or any decent acoustic amp for that matter) will highlight it--voiced amps and effects can mask the fact you suck, which may be why so many people are down on keyboard amps for guitar.

Simple, adequate. I don't need to repeat the discription.

Yamaha P80. I returned this amp for one simple reason, the bottom end breaks up and medium to loud volume levels. I wanted an amp that could aproximate the volume level of a real grand piano, and this thing falls short, by a fairly wide margine. If you intend to use it only for pracitice, to provide soft background music at funerals, don't want to lug around something bigger and are concerned with brand name, then this amp is for you. OTHERWISE, BUY A BEHRINGER KC1200. The sound quality of the KC100 is great (very flat) at low levels, it's just NOT suitable for general live keyboard use because the bass breaks up.

I never used this amp in performance. I returned it and cut my losses on the shipping.

DON'T BUY THIS AMP for general live keyboard aplications. Get a Behringer KC1200 instead. It's $50 less, and you can use it in any live situation you can think of. If you just want it for practice, fine, although you're throwing your money away for a brand name. There's plenty cheaper small keyboard amps out there, like a Rouge KB-50R ($150).

I've recently purchased the KC-100 for my Yamaha P80.

It's purpose is to serve as a monitor while gigging, and a small PA when not.

The amp has four channels, the first with option hi and lo Z inputs. The third (maybe fourth) channel can serve as a monitor channel, though I have not used it for this yet. It does have a line out, effects loop, and headphone jack, but does not include input for a cd player.

As of now, it's being used in place of antique PA system in a small church. It has plenty of power, though I'm constantly having to turn up the first channel when using a mic, but believe it might be the mic itself. It has EQ for bass and treble, but nothing for mids.

I think the greatest feature on this piece is the fact all inputs and outputs are in the back. Plus the controls are inset.

7- Good for what it is, but a few more features would really make this thing great.

As mentioned previously, I run a Yamaha P80 through this as well as a Shure PG58 Mic. This piece is designed to run keyboards so I wouldn't advise it for a guitar, bass, acoustic, etc. A mic sounds fine for speaking, but I wouldn't advise using it for singing.

I play Christian rock/alternative in a band as well as standard worship hymns on Sundays. It holds it own against any other amp running at the same time, and seems to work very well when using it as a PA. I haven't had any problems with feedback, distortion, or buzzing.
9-For those who didn't get it the first time, THIS IS A KEYBOARD AMP!!! Use it right and you'll get a great sound.

I've only had my KC-100 for a couple of months so I don't know much about the reliability. It seems to be solid enough, and it's traveled quite a few miles already.

8-So far so good.

I've been into music for over 10 years now, and play anything from bass to guitar to drums to vocals. I currently own a Fender 25B for my bass and the Marshall AS50 for my acoustic guitar. I have two Shure PG58's and a Beta 58 mic.

If it were ever stolen, I'd wouldn't think twice about replacing it, though I may go for one of its big brothers.

Though I wish it had just a couple more features (i.e. EQ on each channel, built in effects), I really enjoy using it as a keyboard amp and a small PA. It's done well so far, and I look forward to pushing it to new levels.

As far as keyboard amps go, I've not found a whole lot of selection. Most keyboards have built in speakers and/or are run through PA's. I was looking for something more compact, but with good sound, and found it in the KC-100.

He is risen!

This is Roland's entry line, SS keyboard amp, with 60 watts, a 12" woofer and a tweeter. It has four inputs, one with XLR or 1/4", Low and High EQ, Line Out and Headphone. Channel 4 only comes out of the keyboard speaker, not the Line Out.

I bought the amp to use as a full-range amplifier for my guitar processor. Musical styles range from blues to high gain. I had to disable the tweeter as it could not handle ANY distortion and made ALL sounds too bright (the brightness is not surprising as it is a keyboard speaker, not a guitar speaker). The 12" speaker produced good tone with lead work, both clean and distorted, but couldn't handle rhythm playing. It was very "boxy" and rattled badly at 50% volume settings.

Based on the comments of others, this is not Roland strong suit.

I've been playing guitar for a long time, but only a couple of years on electric. For amps, I own a Fender Blues Jr. and a Yamaha DG80. I am returning this amp and would not buy again. It seems that this amp would only work for someone who played alone and did not want to have any loud or bass tones. This amp would not be suitable to anything else.
