50 Cal + Mods.

Yo all. 1st post though I have been lurking for a while.
I keep seeing references to mods for 50 cal plus but can never seem to find the links.
Have searched forums. No luck.
I'm interested in bias pot mod, Lead chan mix? pot and anything else that has worked.
Love the amp, playing latest Tele Deluxe and Emmons Pedal steel through it. so am looking for clean sounds.
But would also like to balance the clean or blitzkreig options between chans.

Cheers .MB

I think this is what your looking for: at least a separate channel vol.
