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

Skreddy - Lunar Module

[The three knob standard Lunar Module]

[5 knob Deluxe Lunar Module]

Marc Alfs of Skreddy pedals is a top builder, he creates some of the best "Pink Floyd" tones there are out there. Here's the description from the Skreddy website:

"The Skreddy Pedals™ Lunar Module was designed for "that" certain silicon fuzz tone guitar solo I fell in love with on a best-selling 1973 album [sic - Dark side of the Moon!]. I intentionally voiced this thing aggressively so it will cut through any mix. Very satisfying and addictive "vintage" fuzz tone.

Unlike typical silicon fuzzes, which can sound thin and raspy, the Lunar Module has a dense sound that can be darkened to taste.

Classic late 60's/early 70's fuzz tones with extra control, versatility, and added noise reduction. Using 3 transistors instead of 2, a pre-distortion bass control, and a post-distortion treble control, the Lunar Module yields a multitude of uses."

And here's a description of the controls:


Volume - This sets the output volume. You can adjust your Skreddy Pedal to roughly the same volume as your bypass signal (i.e.; “unity gain”) or you can boost your signal for a fatter tone.

Fuzz - Takes you from gritty, touch-sensitive overdrive all the way to aggressive, saturated, slightly sick fuzz. Warning: it can get noisy at high settings.

Body - Dials in the amount of bass going into the fuzz section, for everything from tight overdrive to full-voiced distortion to thick, nasty fuzz. Warning: it can get noisy at low settings.

Brite - You can get more brilliance and “hair” or make it darker and smoother, to suit your amp and taste.

Range - Sets the gain of the input transistor. Turned all the way up, the Lunar Module will be fuzzier and more aggressive, but also noisier. Turned lower, there will be a darker, tamer response. I tend to like it about 20% backed off from max."

And here's a demo of the Lunar Module in action:

You've got to admit it sounds pretty damn good! Marc really does wring the best tones possible out of his circuits...

Well, the schematic is available thanks to Marc himself:

As you can see it's basically the same as his Screwdriver with parts substitutions but don't dismiss, they mke a big difference (Marc is well know for being very particular about his parts selection and actually uses it as an integral part of his design philosophy). Now go and build one using this vero layout by gilmour_pugliese and play Dark Side of the Moon over and over and over again:
