I recently bought a Fender Bassman '59 RI. Can anyone give me any advice about swapping the 12AX7 tubes for less feedback? Which preamp tubes need to be swapped and what is the best tube configuration?
I'd be really interested to hear from other players as to their favourite tube configuration with this amp.
