This one has been requested for a while. There seem to be several versions of this circuit so I guess we should start with V1? There is several schematics online, all of them have different wiring for the Bass and Treble controls. So the lug numbering may need some corrections.
The stock Rumble Fuzz suffered from not being loud enough. Dead End Fx decided to take care of that and added a J FET booster after the Volume control (it is labelled "Fuzz", not sure why....).
The layout below is verified and this is now a loud, hairy, air moving fuzz indeed. I used a BC109C (hfe 650) for Q1 and a metal can 2N2222A (hfe 200) for Q2.
