One of my favorite guitarists out there (due to his unique playing style and distinctive tone) is Steve Albini (owner of Electrical Audio and is in Shellac). There have been various threads and posts over the years trying to disect his tone. There are a few factors, Travis Bean (TB500) guitar and brass picks to name a few, but one thing he uses is the Harmonic Percolator fuzz pedal by Interfax. Now these pedals are hard to come by now-a-days, but there are a few clones, and you can find schematics out there on the internet. I found a video by gearwire which has a interview with Steve Albini where he talks about the harmonic percolator in great detail.
Here is another video showing a Fredric Effects Harmonic Percolator Clone. They have a few great pedals there. I’ve contacted them in the past to see if I could personally demo one of these.. maybe some day it’ll happen. I’ll keep my fingers crossed!
If these pedals interest you, I would contact Fredric’s and see if you can pick one up, or keep a third eye on eBay. I would use PedalNerd.com for finding Harmoic Percolators on eBay. These pedals are not for everyone, but might be the right flavor for some.
