Overall this little amp is hard to beat! I've been using this amp for a year with my yamaha dtx4 e-drums. Great highs, lows, does not distort even at high volumes. I've had many e-drumsets, and many monitor/small avinue amps and never heard any better ambient/realsounding e-drums.....ever. works great w/vocals, Many of my Friends have played their acc. guitars through it and were more than impressed. It is light to carry also! here goes.... The only thing I wish it had was phantom power for mics. Oh well it's very close to Perfect

I got sick of lugging around the bigger kb4 (another great amp, now serving for rehearsals) for our piano player and am very happy with the kb3. We have used it as a vocal monitor with wonderful results and have used it in small rooms with a microphone plugged directly into it. We play big band jazz and are not as loud as a lot of rock groups (still pretty loud), so this works well. I put some side handles and good sized wheels on it myself, which helps lifting it in and out of the truck and rolling it on the floor. I plan on buying another one to serve as a vocal monitor and put some side mounted tilts on it.

I've played piano for 11 years but only recently started playing in a band. I bought this thinking that it would be a great amp for the money, seeing that it was 80W and weighed so much. Initially I was quite happy with it, but when I plugged both vocals and piano into it at the same time it gets really buzzy and distortion-y once it's turned past about 50% of its volume. With piano alone it takes about 65% volume to get a really poor sounding distortion. This amp is not good for gigs, and barely adequate for practice. It's kind of embarassing when your guitar player's 15 watt practice amp is louder than a 60W amp. Overall I wouldn't reccommend this to anyone, because if you're serious enough to need a serious amp you're better off getting a roland or behringer rather than this, and if you're a casual keyboard player you wouldn't want to lug this around because it is amazingly bulky and awkward. Not impressed and I plan on selling it.

This amp is a hell of alot bigger and louder then i expected and worth every dollar paid.

I recommend it alot, i am just using my keyboard through it using both inputs so i get stereo sound and it sounds amazing! With the option to add a extra cab theres no reason not to get one.

This speaker had a great sound initially in the store and at the house, but when playing in actual gigs and concerts, i noticed that the pianos are muffled, doesn't have a nice bright sound. Sort of muddy. Also when u have to get loud, a lil distortion does occur, so if using this as your main sound, either go to a bigger size or try something else.
