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

Clay Jones Overdrive

The saga continues. Some say it is a Landgraff clone, others dispute this. Of all the Gut shots and images of the CJOD I've seen they all seem to point towards a Landgraff clone.

As lautmachine of the Freestompboxes forum said: "Can anyone show evidence to suggest that any of the 50 CJOD's were not TS / Landgraff inspired circuits?"

Here is a version that Clay produced early on:

Clearly you can see it is a Tubescremer derived circuit: Input buffer, output buffer, opamp, asymetrical clipping diodes - it's all there.

Now, later CJOD pedals had a differing layout to them. Analogguru, also of the Freestompboxes forum, posted up this tracing of a later model of the CJOD:

This tracing matched up with at least 4 other later production CJOD pedals:
No. B11 for Donner Husk (Donnerbox)
No. B17 for "Smudged" (The name was smudged out in the picture)
and two others of unknown serial numbers.

As you can see for yourself, the later model CJOD layout still conforms with a Landgraff/Tubescreamer clone with two LED's used for clipping. Minus parts values we pretty much have here what it is. Unless someone can prove me wrong!

So, anyone want a CJOD Clone? Contact me, I'll be happy to sort you out ;-) haha.
