Thanks for this apollo! I can imagine how complicated is tracking smd. Did you verify the schematic?

this is pretty close. A few component values here and there, wrong FET and IC, but it does the job. I never thought these sounded as good as my original version. (And they screwed me on royalties in the license agreement) The current V3 G-King is a different circuit all together that's a bit more flexible and much more humbucker friendly.
