Here is a layout of the latest incarnation of the DAM Grease Box.
An output cap blend has been added so now it's basically a 3 knob bender with capacitor values tuned for modern sounds. This one is verified and has been on my pedalboard for 4 months and it's gonna stay there since it's one of my favorite dirtboxes ever.It's more like a firm fuzzy distortion with lot's of comlex harmonics underneath the dirt. And the added tone control is perfectly tuned.
I used a couple of soviet MP40B for Q1 and Q2 50Hfe and 70Hfe respectively and a japanese 2SB437 with a Hfe of 150 with quite a bit of leakage, 0,35mA.
