Thanks ST, I have a DIY HP with the sub mod that i built with your help after seeing your video (mine also with almost 100% recycled parts) and an original Shin-Ei FY2 (the epitome of buzzing evil IMO and I haven't heard a clone that gets the same angry tone). I'll stack them up and see what they're like.
Thanks all for your suggestions, last night I decided on what I'm gonna do....
It's actually a pedal I tried to build a couple of years ago but I had an issue with part of the circuit that made me crazy and forced me to actually physically break the pedal.
Anyway...
I took on board the OD/Dist + Fuzz paradigm and remembered how good the Harmonic Energizer was into a Fuzz, and vice versa.
So I'm going to do a Harmonic Energizer modded for more gain and with switchable clipping diodes to give various flavours of boost, OD and distortion as well as wah of course, into an Axis Face, maybe with an NPN germ in there, with my own mod I accidentally invented by being crap at electronics where instead of a distortion pot, there's a bias pot on the emitter of q2. There will be an order swapping switch.
I'll build three of these. One will have a Green Ringer tacked on the front, one will be plane Jane two circuits with a footswitch for each, and the third will have a rotary to activate and set the order of the circuits with a single footswitch to engage the whole lot and a soft switch momentary for feedback/oscillation and maybe a starve pot too. All will have an expression pedal socket for the frequency control on the HE. I've ordered boards for the HE's cos I can't be bothered to muck about with stripboard at the moment, but the rest will be built from scratch. I would like to add an LDR for control of the HE frequency but we'll see, it needs a 50k pot and all my LDRs are 100k so I guess a 100k resistor in parallel would make that work?
For the graphics I want to use an old video camera I found and try taking pictures of the TV for some grungey, psychadelic VHS distortion. I'll print the images out and paste them onto the enclosures then varnish over the top - done this a few times and it works pretty well as long as you find the right varnish.
We have a stuck thread for finished DIY projects....maybe we should have one for unstarted DIY projects!
