Folks, this is a thread for musicians, not for Motörhead equipment!
The Super Bass is a bass amp, but almost identical to the old Super Lead. There are only minor differences in the circuit. The Super Bass has a treble cap, IIRC.
There is no reason not to use a Super Bass for guitar playing, as well as I sometimes play bass over my JCM 900 (which clearly is a guitar amp. Sounds cool, anyway).
After listening for over 30 years, searching and waiting for alternatives, I understood that there will be no other band like Motörhead. Never.
