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

WEM / Watkins / Rush - Pep Box Fuzz

Early Pre-WEM and GermaniumWEM Pep Box

Later Silicon Transistor WEM Pep Box
The Pep Box is one of those old vintage effects that lives in a strange world of popular mystery - not as widely known as the Fuzz Face, Univibe or Tonebender yet still used by some of the most well known artists of the 60s on some of the most important Rock 'n Roll records of the time. Here, for example is John Lennon and his Pep Box around the Revolver era:

Here's some guts from a silicon model Pep Box:

And the PEP Box Fuzz in action:

And here are the schematics for both the silicon and germanium models of the PEP Box:

And a great vero layout for the germanium version by Sinner (http://www.turretboard.org):

  1. Excelente... vintage fuzz

  2. Very coo stuff. Photograps show that the picture of John Lennon with the Pep Box was taken during the "Paperback Writer"/"Rain" sessions, April 1966.
