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

Fred Briggs - Hummingbird Overdrive

Here's another one. I've had a lot of emails for this one. The best way I can describe it is as an "enhancer" - it makes and already good overdrive tone better! It produces a great low overdrive, the compression and shimmer controls are very interactive with regard to both the gain/clipping structure and the overall tone and feel of the device..

This design was born from a challenge set to me and a few others by Bjorn of BJF effects to build a circuit that sounded like the honeybee. Soulsonic came up with a very elegant and simple design called the Hunny Bunny: http://www.soulsonicfx.com/?page_id=88 (I love that circuit). The Humming Bird De'luxe is what I came up with and you can see the schematic below.

Here's a vero layout by Harald Sabro (http://www.sabrotone.com):

[NOTE] One of the capacitors is marked as 47k on the schematic - this should read 47n. Point B goes to the input of the mosfet stage.

Fred Briggs - Silver Orchid Overdrive

I've been away for a while. I'm back and here is a schematic for you! It's a great overdrive and boost, a development on from my standard overdrive. Add a switch to the diodes for extra fun :-)
