Hi Sorry for the english but there is no information about this amp apart from the german language forums. What does it sound like? I play sixties rock and blues rock.
Sorry but that's a Bass Amplifier. It's All Tube design. This amp sounds very clean about echolette or dynacord bass king or so.
then I guess it's not a tone heaven. I'm looking for that 'marshall dirtiness' that the b40n could so well emulate(okey it's different but still pretty close)
