Colorsound Hybrid Tonebender 2018 EditionVerified
Based on the Colorsound Hybrid Tonebender 2018 Edition
From the post
Couldn't resist to draw a schematic and a layout for this interesting mutant of a circuit that just got traced. First two gain stages is almost identical to a Jumbo Tonebender (except for one cap and one resistor value), the third gain stage is almost identical to the saturation stage in a Tonebender Mk. 3. Transistor bias is quite different with the zener diode, though. Tonestack is Big Muff style followed by a Volume control. Note that earlier versions had 100nF or 470nF instead of 10nF so it might be worth socketing that cap.
Schematic
This is a board layout, a drawing of where each part goes, and the post may link the schematic it was drawn from. Open the layout at Dirtbox Layouts. No KiCad fragment has been drawn for this circuit yet.
