the final tone stack values:

Rslope 100k
Treble 250kB 270pF
Bass 1MA 10nF
Mid 25kA 10nF

It still needs a cab built but I can't stop playing it.

Tony,
Which VVT amp is Mark using?

I always though GFR was a great band.
Recently hear about Marks son becoming paralyzed from a fall, tragic.

Bob, did you keep the 100K/ 221K plates on V1?
Tom

Don't let that smoke out!

Tom,

Yes, Rplates remained at 100K/ 221K. Initially I was going to reduce those values, because the gain was over the top, but changing out to lower mu tubes did the trick. Using a tele w/ humbucker, the volume at 11 o clock (chicken head position) the gain begins to overdrive. At 10 o clock it's nice and clean, 2 o clock is almost too much gain, but for now I'll leave it as is. The strat can get basically the same using slightly wider settings. Thanks for asking.
