The tone control is based on the Big Muff design and can be changed to tase accordingly.
STOCK RESPONSE
The pedal has a bit of a mid hump, which can work, or you can adjust to suit your taste.
Change 470pf to 10n
This is reasonably flat; best to try it using the online tool, breadboard, then commit to solder if you have that option.
