Sorry, Bish – I was forgetting my Englishisms don’t translate. Yes, I meant I use tube amplifiers rather than SS. Incidentally, if you flick off a tube amp (and I mean one with power tubes; not the hybrids with a tube in the preamp and a SS power section) with the volume up, you don’t get that “Whump” noise so much. Instead, if you carry on playing, the output takes a while to reduce in volume and goes farty-distorty. This is because the filter capacitors are still discharging enough juice after the mains has gone to amplify the guitar out through the speaker.
