here's a Dirty Boots I built up in an old tank communication control box. it's got some serious mojo(just for fun;))components, a switch for hi and lo gain, and a single volume knob.

I'm not sure what's up with all these posts about the land down under lately, but I recently ran across THIS great Australian site that has tons of information on Aussie guitar amps as well as building guitar amps and effects. included are a number of old magazine projects from EA. if you scroll down the page, you'll find schematics for fuzz, compressor, "phase vibrato" Leslie sim, and tremolo projects as well as a number amps. be sure to check out the rest of the site, as it's filled with some very cool articles and schematics, such as fsb forumite Phil's cool reverb project.
here is a very cool little pdf from elby electronics from australia. it includes some nice graphs and instructions on how to alter the taper and value of your potentiometers. it's an essential technique for making the most out of your controls.
