This particular one is done on handmade turret board, the rest will be on tagboard.

Ok here we have a small case Doombender mk1, in a nutshell a Tonebender mk1 with larger value capacitors (for theoretically more bass), and a smaller output resistor (for more volume).
Circuit is on tagboard, has Carbon Comp resistors, Russian Mil spec input cap, Tropical fish output cap, OC45 and OC71 transistors, nice build quality.
A heavily modified Tonebender mk1, larger value caps for more bass (Wima, Sprague, Panasonic, Russian Military), output capacitor blend control (similar to the Buzzaround), smaller output resistor for more volume. Turret board and tagboard construction, OC45, OC72, and OC84 Germanium transistors, carbon comp resistors.
