I've got an Acoustic 470 guitar/bass dual channel amp head that is just sitting here collecting dust. Sounds pretty damn good actually, I just don't use it.
I have an acoustic amp. I think it is the 210 model, but I can check for you. Email me if you are interested in more details. It was a combo that a few years back was converted to a head and a cabinet. It is THE FIRST amp to ever offer a graphic EQ on the face (from what I understand) and was used by Jaco back in the day. It is old, but was tuned up not long ago (when the cable was added to connect the head and speaker independently). Please email me at [email protected] if you are interested in hearing more about it or possibly taking it off my hands.
