The KT108 serves well as a general purpose amplifier for limited volume situations. I actually bought a second one and I essentially use them as powered speakers for a small Behringer stereo mixer, through which I run a couple mics, electric drums, keyboard, and on occassion acoustic guitar.

For limited volume situations, the KT108s perform pretty well, and seem to produce the sonic range reasonably well. They are not very loud; by way of comparison a 6 watt Line 6 Micro Spider amp produces (a little) more volume than the KT108 running a guitar into it. As you’d expect from a small amp, they are limited in how much air they can move and can only produce so much volume of the deep bass sounds a 76 keyboard can produce without rumbling. However, for my limited volume needs (ie practicing in a townhouse where I don’t want to bother the neighbors too much) they are more than up to the job, and do a good job with the drums, organ, vocals and acoustic guitar.
