EA Tremolo

This project originated from an article by Anthony Leo in the November 1968 issue of the Electronic Australia Magazine. This wonderful sounding tremolo was brought to the attention of the DIY community on the internet by Greg Nabke.  Lots of builders like this one, it’s simple and it sounds great.  This project features some great improvements over the original. A schematic of the original design is included for those curious cats.
