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.

Tokai Metal Driver

The Tokai Metal Driver was built in Japan in the early-mid 80s and is very similar to the Pearl OD-5 of the same era. In some ways it's basically a Tube Screamer, with the same input/output buffers, but the tone control is rather unique and the sound is apparently very different from your standard TS-9. Original units use 2SC1571 transistors with BCE pinouts, but I've drawn the layout for CBE transistors that you're more likely to have on hand. Here's one of the few demos I could find of it. Skip ahead to around 2:30.

  2. Cant see schematic man, can you attach it on here plz


  4. Thanks man I will build this sucker now

  5. Verified.

    The circuit has a filtered, stuck wah kind of sound, adjustable via the Frequency and Bright controls.

    I saw a couple of threads suggesting replacing the clipping diodes with LEDs, which improves the sound. You'll get less harshness and more volume and openness.

  6. I built the sucker, it's tone pots work great but the overdrive is a bit shitty, needs more gain and a smoother od
