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.
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.
Hey man where is schematic

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