[LAU] Octaver or fuzztone effect

Hi all, I always liked Adrian Belew's song "Big Electric Cat" , and after hearing it again I'd like to see how close to that sound I can get. Doing some googling, Here is a quote from Guitar Player jan.'84: AB describing his onstage/studio equipment p.80- ...number 3 is my Foxx[Tone Machine]fuzztone. That's the sound in "Big Electric Cat" and "Paint the Road". "i always use it w/ the high octave sustain switch on. its my favorite effect, and not an easy one to find these days. i'm also daisy-chaining the Foxx-tone into an MXR 10-band graphic equalizer so that i can eq it." I'm actually a keyboard player with a korg triton classic and some relatively good guitar sounds ;-). I found some schematics for building a cheap fuzztone, but I've got plenty of excuses for trying to do this in software first ;-). Any ideas? Robert
