I simply used the impedance scaling formulas available in the paper on my website entitled "Tone control scaling". I scaled all impedances by the 250k/350k impedance scaling factor (ZSF = 0.714). The new values are obtained by the following formulas: R' = R*ZSF L' = L*ZSF C' = C/ZSF If nobody archived that post, I'll recalculate the values if needed, but it should be fairly straightforward with the above formulas.

I was the one who asked Randall that question a month or two ago and here is what he figured out... C1=350pF (not 250) C2=.14uF (not .1uF) C2=.07uF (not .5uF) C4=.007uF (not .005uF) Slope Resistor= 71.4K (not 100K) Bass Pot= 200K (not 250K) Mid Resistor= 4.9K (not 6.8K) Good Luck!! And if there are anymore questions about that post, I have a hard copy version that I can retype.. Cheers!

I think they were: C1=350pF (100pF in parallel with 250pF) C2=0.15uF C2=0.068uF C4=0.0068uF (6800pF) Slope Resistor= 68k Bass Pot= 200K Mid Resistor= 4.7K Randall Aiken
