Yamaha G100 B212, 100W solid state guitar combo from the seventies. 2-channels with swichable Reverb and Distortion. Compare the sound to the Roland Jazz Chorus. It's clear and superclean. Distortion channel a little over the top as most solidstate amps from that era. This amp is the favouraite amp for jazzguitarist Mike Stern. Our occasion comes technically in a perfect state, the outside shows some marks from live on the road. Overall state good.
