From the post
Here's a pretty interesting overdrive from Lovepedal (Hermida). The signal goes through a dual PNP silicon transistor stage (don't worry, it's still a negative ground effect), then into a op amp gain stage with soft clipping in the feedback loop, with a Rat-style tone control, followed by an output buffer. Schematic can be found on FSB for reference.
