The Superbass has been changed to Superlead specs with a .68 cap on V1 and V2. The negative feedback resistor wasn't changed when it was converted from 6550's to EL34's. Also, the negative feedback loop wire is still on the 4 ohm speaker tap (sounds dirtier). The channels are jumped internally. There is a .68 cap on the presence pot as well. That was per Dave Friedman, and I have an amp set up just like his. It sounds pretty much just like the Undertow stuff. I have a LarMar PPIMV on mine.
