This is a library of perfboard and single-sided PCB effect layouts for guitar and bass. I'm not an electrical engineer by any stretch of the imagination, just a DIY'er who likes drawing layouts. It is meant for the hobbyist (so commercial use of any of these layout is not allowed without permission) and as a way to give back to the online DIY community.

ThroBak Strange Master

Essentially a Rangemaster with a switch selecting the input cap (Hi/Lo) and another switch (Ge/Si) selecting between a germanium or silicon transistor. The bias pot helps to fine tune the bias (imagine that lol) differences between germanium and silicon modes. Other transistors can be used other than what's specified. Something in the 100-120 hFE range for the germanium and something around 250 hFE for the silicon. Schematic here.

  1. Built this a couple days ago and I'd say its verified. Tried a couoke of 2SD30's. One around 50 hFE, and one around 160 hFE. Preferred the 160 hFE. Sounded a little muddy until the boost knob got past 2 o'clock or so.

  2. It is possible to use a Russian MP38A in place of 2SD30?

    1. I would think so. I've built several Rangermaster clones with those.
