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 - Wah Wah

Here's a Wah Wah I've built. It's based around the old Vox Wah (How can you tell!?) but it's got a few cool extras:

1) Input and output buffers so you can use it with all your stompboxes without it playing tricks on you.

2) Adjustable "Blend" control which allows you to blend in some clean signal with your Wah, this actually makes a real difference and allows you to wah wah away without completely Wahing out everything else you're trying to do. It's one of the best mods I've done to a Wah. You could in fact use the circuit I installed to run a "dry" signal FX loop which would then allow you to place more FX into the dry part of the blend circuit. Very cool but I haven't yet done that - this is enough for now!

3) Standard cap, inductor and resistor tuning to suit your own tastes!

    Could you please post a schematic or layout for your Wah blend control? Best idea for a wah mod I've heard of. I'm hoping to add it to a vox 847.

  2. Hello.Do you have a layout for this?Thanks!
