I built this pedal a few years ago and it seems to have changed hands a few times and gotten some awesome authentic battle damage along the way. I came across somebody selling it on ebay this morning and thought I'd share. http://www.ebay.com/itm/Mesa-Sound-...721015?hash=item2ee92fd277:g:WRUAAOSw7FRWYfza It's the lead channel preamp circuit out of a dual rectifier, shrunk down to use JFETs (transistors) instead of 12ax7's. I can vouch for it's tone and you will not find another gain pedal you'll like the sound of more. Some dr boogeys come out sounding terrible, but the ones I build do not. I've no idea what the other guys are doing wrong, lol. Anyways, thought I'd share. I'm actually considering buying it myself.
