From the vendor
A de-gooped Lovepedal Eternity, which the post shows is a modified version of Jack Orman's Son of a Screamer: a minimal Tube Screamer with one op-amp half as the clipping gain stage (four diodes, two in series each way, in the feedback loop) and the other half as a buffer after a passive tone control. The author built it on perfboard as his 'Lovestuff Ecstasy Overdrive', with Drive, Level and Glass (a standard tone control) on the panel.
The vero layout notes the gain pot is 500k, sometimes 1M.

Check before you build · 2 values the reader of this schematic was not sure of
- The schematic says the IC1 type is unknown; the vero layout gives an LM1458N.
- The vero layout by Lovepedal Detective (image 14) uses different values and numbering from the schematic (e.g. C4 47n where the schematic has 150n for the filter cap, no 20k in series with the Drive pot); rows follow the schematic.
