Ken Fischer was a great guy. I called him one day and yakked amp circuits for a good 20-30 minutes about one of his articles. (in the Trainwreck Pages). Yup, just some random guy that found him through the internet. and he was willing to take the time to talk amps. Found my copy of those just the other week. I can't remember if he sent me the photocopies I have or if someone else (also now if not as famous as the brand, the genious behind a hot line of effects.)
Total opposite of the Howard Hughes of guitar amps.
