Harmonic Percolater

Thanks guys.

Here's a sound clip of my "Brick": http://home.cfl.rr.com/dbhammond/Brick.mp3

All the guitar sounds are through the harmonic percolator. Rhythm gtr is neck pup with the gtr volume rolled down a little for the "semi-clean" sound. Most of the lead is with the bridge pup, and the gtr vol is varied to demonstrate different sounds. The gain on the perc is maxed.

I used a millenium bypass ckt for the LED, you can see it in the lower right hand corner of the perfboard. Check R.G.'s site for info on the millenium bypass. I did it real simple with a J201 JFET and 1N4148 diode.

I used fleckstone spray paint on the RACO box. It's a real pain- I wouldn't recommend it.  It took several coats because as I tried to get the paint to cover, it kept blowing the paint off that was already on there. In retrospect, some primer may have helped, although it says on the can you don't need it.. After 2-3 days it was still wet so I threw it in my toaster oven to dry it out. Amazingly, that worked and it put up with all my abuse. After all that, the coat is so thick it covered all the lumps and bumps of the RACO box.

Thanks for the comments.
