I made some inroads towards tracing the PS-001 Distortion.

Turns out it is more than an MXR Distortion+ with a Muff tone control. Structurally it's more like a Boss DS-1.
(Given the similarity of the Guyatone PS-005 Overdrive to the Boss OD-1 it's not surprising there is some similarity to the Boss DS-1.)

Unfortunately there's some ambiguity regarding the tone control caps. (The two polyester caps on the middle-edge of the PCB where the wires are).
