The Cornish ST-2 was originally designed for David Gilmour, and released as a standalone pedal in 2007. David is notably associated with the Colorsound Overdriver and so it was suspected that the ST-2 was Pete's take on the Overdriver, although some ST-2 owners of course swore it had to be a completely different circuit.
So you know what that means: it's a cue to get in there and do what we do.
Schematic:
Verdict: yep, it's based on the Overdriver, but with the usual Cornish spice - several different component values, input buffer, gain stage.
