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 :-)

Lovepedal - Black Magic Distortion


Here's the Lovepedal Black Magic (the photo shows a pedal board with the Black Magic in the top right corner). There is only sparse information on these around on the internet but from what I've managed to cobble together it was a pretty old design that was an attempt to get some Eddie Van Halen "Brown Sound" tones. Greg over at freestompboxes.org picked one up and duly traced it out. Here's the schematic:


As you can see it's a very simple 386 based distortion, some people reckon it's based on Aron Nelson's "Smash Drive" circuit:


To be honest the circuit is so simple it's hard to tell if it is or isn't. Personally I don't like the sound of this thing, the distortion is crackly and the decay is gated and unmusical - I can see why Sean took it out of production pretty quickly!

Here's a vero layout by mcaviel, it's unverified but a quick check suggests it's OK:


Here's the freestompboxes.org forum thread for reference: http://freestompboxes.org/viewtopic.php?f=7&t=12735
