From the post
Today we've got the Lovepedal Hi Volt. A wide variety of tones on tap with this one. It's a cascaded JFET gain stage into an active EQ section, all powered by a 16v charge pump. Laid this out with on board pots and will fit in a 125B with top mounted jacks. Here's the schematic for reference.

Check before you build · 4 values the reader of this layout was not sure of
- 820K at columns 7, rows M-N: the populated board prints what looks like '882K', the wiring diagram prints 820K clearly; 820K taken
- 220nF at the bottom right (rows U-W, next to the vertical 1N4004): printed 220nF on both views but drawn as a large polarised electrolytic can, so it may be meant as 220uF
- 50nF under the Bass pot label: printed clearly, unusual value
- 250pF in the bottom row: printed clearly, unusual value
