If you’ve ordered up our JDM Pedals “NPN Germanium Transistor Kit” (or have your own selection), then you’re ready to build some KILLER pedals. For the Tonebender Mk2, try lower gain (60-80 Hfe) in Q1 and Q2, and an AC130 in Q3 (they have a bit more leakage, which is good in this position) with the higher gain range (Hfe 90-120).

Here’s the layout as a PDF: tonemaster_mk2_layout
