Circuit Wizard
I started learning circuit theory as a kid by reading magazines like Popular Electronics. In the Feb 1968 issue, they ran this article on building a Fuzz Box. That article was a reprint of a DIY article in Electronics Australia from August 1967. I built one of these in 1975. The circuit bears a strong resemblance to the Fuzz Face. The schematic contains a typo: there should be a 1nF cap between the wiper of the FUZZ pot and the FUZZ/NORMAL switch. The circuit is not true bypass and in fact it does not run perfectly clean in "Normal" mode. I didn't like it for guitar, but it did sound cool for bass. The "how it works" section is not 100% correct, but it's close.
