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.
