Great sound, great features, great amp!I bought my KB 4 as an upgrade to my aging KB 3, which I bought when this series was first introduced. I was pretty happy with the KB 3, but it was beginning to show its age, and becoming a little flaky after 8 years of use. In my new amp, I wanted one with the same feature set as the KB 3, but with a bit more oomph.
The KB 4 sounds great. The highs are nice and smooth, and the bottom end is nice and full. Overall, the tone is very well balanced. All the controls feel smooth, and the connectors are nice and tight. Typical of Peavey amps, it's built like a tank. Well placed, heavy-duty hardware makes moving the amp relatively easy, despite the weight.
I have only one "complaint" with the KB 4, which is the master effects loop. It's a stereo effects loop, with no mono switching. All of the channel inputs allow connecting mono inputs on the left channel, and like most mixers, the input is then sent to both left and right buses. The master effects loop is also stereo, but if you run a mono effects rig (like a standard pedal board), plugging into the left channel does not split out to both channels. So, when the signal is then summed to feed the power amp, the clean signal is summed with the effected one, almost negating the effects. The work-around, of course, is a "Y" cable on the effects loop return, but that's an extra cable to cause problems on a gig, and I wish that Peavey had some sort of mono-switching on the master effects loop.

Man is this amp big!I purchased a guitar synth recently from Sweetwater that sounded poor through our Fishman Loudbox acoustic amp. Roland recommended a keyboard amp or PA...
...So, I bit the bullet and purchased the KB4 from Sweetwater using their 10% gift card discount.
First impression...Man is this box huge. It dwarfs the Loudbox. Weighs a ton (80 pounds +/-). Thank heavens it has rear casters and a pull-up handle. Kinda wish it had casters at all corners. It is a beast to move around. Good thing I am a big guy!
Regarding Sound Quality...
The before-mentioned synth sounds great through the KB4, even given that the KB4 is not a "stereo" amp.
My modelers (amp and effects) also sound great through the KB4.
And my steel and nylon guitars sound great through it. Ironically, the only instrument I have not tried (yet) is a keyboard!
The KB4 has a bold, somewhat bass-leaning, crisp and tight sound. No muddiness at all. Just an in your face, clear, hum-free, buzz-free sound. I am very impressed.
I like the mixer. I could use one more set of stereo line inputs (like the KB5). But it handles three sets of stereo inputs which is probably enough for most folks.
I chose the KB4 over the Roland models because the KB4 offers send/receive connections. The KB4 and Rolands do not have effects, reverb, nothing. So, I wanted the send/return for outboard effects. Also, the KB4 offers XLR balanced L/R output connections for a PA, mixer, etc. The similar Roland model does not.
There are a couple of cons:
1. I could use one more set of stereo inputs.
2. No ability to chain another keyboard amp for a left/right stereo setup.
3. Master volume pot is stiff.
I highly recommend this amp for its clear, faithful, in your face sound, its quality reproduction of the synth and amp modeler outputs, its mixer-connectivity options, and the low price. And it is an impressive (and massive) acoustic guitar amp.
