I just picked up a 70's Roland Cube 20, one of the old orange ones.
Mod# Cube 20 Ser#088702
Impulse buy, friend had it, I knew Roland was good stuff and it was heavy. And orange.
I need some trouble shooting tips- The reverb doesn't work. It makes noise if you whack the side of the amp. I found a schematic online, but can find no other info on this amp.
Any idea of a price range for these?
