i have just read up on talkbass,
.found a wiring diagram......might be that thats the problem?(as 1 of the speakers is moving a bit differnt to the others)or might be higher ohm speaker put in? (he thinks they are the original speakers??).i have only just got it back from the practice rooms tonight and not had chance to strip it down ,so tomorrow is going to be my full check!
it is the ported 1 mr.foxen.
they run 2x 6ohm in parallel so 12,12,12ohm in line ...so if i had to put 2x 4ohm or 8ohm to next to each other to replace 1 of the 12s would it still be farting at all? (only a short term sollution)
