Me neither. That's why I was trying to encourage experimenting. :)
The Fulltone Soul Bender uses a trim pot to simulate some leakage at Q3. Guess their transistors weren't leaky enough.

The one I built last year with the 220k/47k bias string sounded better with the leakage simulation trick. But 1 meg between B and C is what got me to similar voltages as vintage units. That 500k trimmer on the Soulbender makes me think what they use for Q3 must truly have zero leakage.
