I have been in one situation where there was no option since Mercury Magnetics had the only PT that fit the requirements. All of the MM products I have used have been great. RE: Classic Tone....I read on THe Gear Page today that ClassicTone is on the way out of business??? The site is still active, and their parent company Magnetic Components deals in much larger concerns than guitar amps. Dave Friedman supposedly brought this question of ClassicTone’s demise to light recently?????
