Interfax Harmonic Percolator stripboard layout 23rd October 2008

Based on the most recent, general consensus schematic (apparently the pedal 'evolved' during its initial production). It's a nice easy build, and you'll only have trouble sourcing the transistors. It sounds really good, and it actually does lift the harmonics out of the general fuzz/crunch. Sounds pretty accurate to my ears, but then I've never owned a real one. Can't get teh Albiniz as I've stashed my Electrical Guitar somewhere safe and I'm testing it into a Fender Deluxe Reverb.

Harmonic Percolator stripboard/veroboard layout

Here we are. Finished in finest blue/brown gingham with a laquer coat for longevity. The switch disengages the diodes for loud/openness. I also noticed, whilst playing it properly for the first time last night, that there's a really nice kinda compressed clean sound when you roll the gain off. Also that there's probably not too much need for an extra boost circuit after the main one.
