Thanks D..wonder. The amp only goes up to 10 (!) but I realise I'm really asking whether the maximum noise available from the amp will be the same, whichever bass/input signal is used. It won't cost me much to find out.
Thanks Ed. My bass is a passive Mustang and I expect some basses have a higher output so it's a similar situation, and it'll be reight because I'm in Sheffield!
PS My very first amp was a little Park, till someone jemmied our back window.
cheers both, Mark
