Several seemed surprised that a Fender could get into metal tone territory in the Super Sonic does Metal thread. I have a Super-Sonic head and knew it could get pretty heavy but doing metal without a pedal is a stretch. The real Fender Metal Monster was the now discontinued Bruce Zinky designed Prosonic. There are no effects here other than the wah on the solo track this is all Fender Prosonic gain. I played my 94 handbuild Washburn USA prototype with a EMG 85 into the Prosonic sitting on my 4/12 with GT12 75 Celestians and I used a George Dennis wah on the solo track. The Fender Prosonic has more gain available that a TSL 100 Marshall head does. http://www.box.net/shared/luoytg2qso This is with me having NOS Mullard 12AT7's in V1-3 on the Prosonic to KILL some gain and it's still not running much over 5 on the pre gains.
