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

HAO - Rust Driver

This thing is said to emulate a 69 Marshall Plexi 50W on 10... Hmmm, OK - Here's the scheme :

It looks like this one was drawn by the great matsumin, one of the legendary Japanese DIY bloggers! Check it out, it's a fairly simple build!

Here is the original PDF Manual: Link!

Here's a decent demo of Hao Rust Driver in action:

Once again. A big Thanks to the Freestompboxes guys for getting this info together and to the people who created it in the first place!

Expect more schemes soon - or just join freestompboxes for a sneak peak!


  1. Wow, thanks, I'm going to try this one. But what I miss in the schematic is the 3-position equaliser switch (Normal, bright, warm) Anyone knows how this looks?
    thanks eljee

  2. insert 3 different caps in parallel with the diodes and switch them:
    try 22,47 or 10 nf

  3. What does the 4 Pin in the Lower Corner mean?

    Really nice thing :D

  4. The bit that says 4 Pin is a reference to the 4th pin of the IC going to earth.
    BTW: This is a very similar design to the Op amp Muff fuzz schematic on fuzz central.

  5. I did a PCB print layout based on this schematic if there are someone interested... it's posted here:


    Thank you for providing the schematic

  6. "insert 3 different caps in parallel with the diodes and switch them:try 22,47 or 10 nf"

    Did you mean 2,2 4,7 or 1 nF? (0,001uF; 0,0022uF; 0,0047uF)
