Finally. This one took forever. A neighboring guitarist uttered (I hope, he really meant it), he'd like a Russian Big Muff combined with a tonestacked Tonebender.
As an exercise I layed out the GGG Toneburner and the GGG Russian Big Muff anew and threw in a Rangemaster for good measure (the combination of the Rangemaster with either Tonebender or Big Muff sounds really good). The whole thing looks a wee bit untidy. It is very quite nonetheless. Next time I'll spend more time on the placing of the potentiometer pads (I am no Francisco, unfortunately)
It contains a ICL7660S voltage invereter for the Tonebender and the Rangemaster, so the whole pedal is powerd by a standard PSU.
The pedal contains some extra switches: The Tonebender sports a "Normal – Tame" switch, that biases the Q1 collector to about -8V in the "Tame" mode and about -4,5V in the "Normal" mode. The trannies are AC128Ks. Hfe Q1=60, Q2=80, Q3=108. The Q2 emitter cap is switchable with the 1p12t switch with a huge range of quite dark to wah-pedal -stuck-at-the-top sounding. Quite nice for cutting soli, I guess.
The Big Muff has both back-to-back diode pairs switchable. This makes the pedal very versatile because it can be stacked much better without one or two clipping stages.
The Rangemaster has a additional 4n7 cap for the "Full" mode (should be called "Fuller" because it is still not a linear booster).
The circuits are connected by switched jacks. So if you plug it in as is, the order is Rangemaster->Tonebender->Big Muff, but they can be tapped individually and re-ordered with patch cables.
I think that's it.
