I can't believe we got 11 posts into this thread and no one told Flameboy about Patrick's kits. (Which, incidentally, are mentioned in the "Where can I buy one" section of the FAQ now).

Flameboy: One of the empeg guys is planning on making tuner module kits and selling them for (it is hoped) about $160.00 US. They should be available within the next couple months if all goes well.
