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 :-)


Feel free to get in contact with me about anything you see on this blog or with any general questions about guitars, amplifiers and effects, I'll be happy to answer! Just click the button above to email me directly or alternately my email address is fredbriggs2007 [at] googlemail [dot] com

Jen (Gretsch Playboy) - Harmon Booster

Nightraven has taken his apart and offers some description of the tone of this strange unit: "it's basically an overdrive pedal that borders on fuzztone with the controls dimed and having a dirty amp to start with. very underrated IMHO - i think it's loads better than Tubescreamers and the various copies."

For a better idea of how it sounds check this demo video out:

Soniciv also uploaded a schematic for the unit:

8 transistors! Yep, they aren't all gain stages though as you can see there's quite a few buffer stages in there with a big muff type tone control at the end of the circuit (with a buffer either side of it!)...

And here's a great vero from Sinner over at turretboard.org:
