These Boss units are well known for their earthy, 70s sound and this one does not disappoint. 6 Channels all with level, treble, bass, effect level, pan and a 3-stage input attenuator per channel.
Master section with Master Volume and the Effect return controls for the left and right channels. Also the monitor output control, the switch for low cut filter on/off and power on/off and, of course the rad backlit VU-meters are there. Like all BOSS products this baby is built like a tank.
Plenty of modern applications, but notoriously these are used for summing drum machines, samplers and synths with the benefit to overdrive it, to get the warm characteristics and distortion that lies within this wonderful piece of gear.
It shows minor wear of use, but is really clean for it's age.
