Hey Guys,
After posting the original schematic, I went ahead and also designed the Green Ringer -> OKF -> Muff Tonestack (+makeup stage) that I mentioned.
I also modded the original design to allow for an Electra Distortion to be built into the first stage, rather than an LPB.
I've copied the revised schematic (and PCB layouts) below:
So, I got the PCB's back from Dorkbot and built both these suckers up.
And.... they are MENTAL.... in a good way of course
!
The LPB -> Bazz Fuss -> OKF version is the most mental of the two; there is an insanse amount of gain and fuzz available with this circuit, but it is tameable.
The external bias control helps as well, as it can be used to 'gate' the fuzz.
The Green Ringer -> OKF -> Tonestack version is my favourite I think. I can get a load of cool fuzz tone out of this thing.
I'm really liking these two combos. You can easily get 'noise' tones (ala Dwarfcraft/Devi Ever etc.) out of them, but you can also get more traditional drive/fuzz tones as well.
Anyway, I'm definitely going to get a small batch (10) of each PCB fabbed for you guys to try out as I think these are really cool (in fact they are the most fun I've had with fuzz for a while). I'll probably sell both designs in one bundle to try and keep the costs down.
I'll get some soundclips sorted out too.
