Hey All!! I finally got it down! (for now) The best OD sound yet!(V32H) Put JJ's in power section and Mullards in the pre's. I tried dozens of combinations with RFT's, Bugle Boys, RCAs, and other US tubes, even some old Japanese 12AX7's. EQ: all @ noon and Pres ON no, mid boost. The best part is that hum on the OD side is really much quieter with the Mullards as well. At the front, I'm using an LP Classic stock pups. Great sustain, pinch harmonics, and it cleans up with just a little hair as you bring down the vol pot. I don't miss my Marshalls! (and the weight) What's up with yours? Rick P.S. The line in and out efx loop works just fine as well.
