Welcome to the Revolution

Hi there, welcome to my blog - La Revolution Deux. It's an odd name - but I like it! Here you will find all the info on my various DIY Guitar effects builds, amplifiers and guitars. Everything from a humble Ibanez tubescreamer to the holiest KLON Overdrive.

You may also find a few effects builds that I am looking to move on - usually in exchange for other effects/gear/cash. You can always check my ebay account to see what I've got up for grabs.

Have fun, enjoy the blog - Fred Briggs :-)

Fred Briggs - Octave Ringmod Fuzzer (ORF)

Here's the next new project from myself. It's a fun little circuit for you, inspired by Tim Escobedo's Tripple Fuzz. At lower gains it creates a really sweet tone, push it high and it gets truly evil! Stack it into other gain pedals for an absolute fuzz out heaven :-)

Here's the schematic:


The transistors I used where BC557 and BC548, the op amp was a LF351. The optional J201 gain stage adds a lot of character, I prefer this build with it...
