3 independent channels, including one with mic input. The latter is of no use, except as a temporary solution when you don't have a mixer around!
The manual...What manual? There's no need for one.
I have lugged it around with me for rehearsals and gigs (as a keyboard monitor) and it doesn't even cough. It's electronically infallible and the housing is indestructible. The speaker it just like the first day.
I've used it 20 years for keyboards and vocals during rehearsals. You plug in, turn it on and it just sounds!! Super powerful (even too much) for a typical rehearsal room.
3 channels, 15 inches...It's originally a keyboard amp, I think!
I have used it a lot for vocals during rehearsals...Then vocals and bass, it's awesome for bass (15"). And currently I use it mostly for guitar with a Boss disto ds1 pedal and it really rocks! And I've had different amps!
I think this is a true all-purpose amp, and a sturdy one, too!
It must be 15 years since I have it and I haven't had a single issue, even though I've abused it quite a bit!
After 10 years of use, I had to write a review here.
It's an IMPLACABLE amp!!! It has never broken down, it is very, very sturdy and truly VERY versatile.
It's a keyboard amp, but it can be used for anything!!
At first I used it to amplify two acoustic guitars and my vocals (it has 3 inputs!) for rehearsals and gigs, and it performed great.
I then used it several years as a PA system for vocals during rehearsals and now I use it as a bass amp and, to be honest, it sounds awesome!!
I am very happy with it, it's my oldest amp and I do not intend to part with it.
In short, this amp is truly extraordinary!!!
