A little workhorse. I've had one sitting in my office for probably 10 years. It has a NP-30 piano, a fretless Jazz bass and a Godin jazz guitar plugged into it. Often, on roughs, I'll line out into a Zoom H-2 or 4. Add a little drums; usually from a Ketron SD-5.
I use a Pa head for multiple channels when playing out, but wouldn't hesitate to use this little monster for small jobs where a lot of sound dispersion wasn't needed. Don't think it's really great for vocals. Jazz guitar is fine, but anything with more texture would require an effects processor of some time (maybe a SansAmp).
All in all, a fine little unit for a Keyboard player with multiple keys or a keyboard player doubling on bass or guitar.
