Matrix model MA100SC vintage 1990s guitar amplifier. Two channel amp with EQ, reverb and stereo chorus, kind of like Kaman's (Ovation) smaller, cheaper version of the Roland Jazz Chorus. Quite a rare beastie, actually, you don't see too many of these around. Works and sounds great. The last pic shows this amp in the 1994 Ovation catolog, just for reference. Call for best response. Cash only, please.
