Hi. How much do you know this schematic? Did you listen some demo?
I emulated it, and it sounds very bright. I'd say it need some treble cut somewhere, or at least leave out the 3.9k resistor in the tone to tame a bit more highs.
Perhaps change the tone, I don't like too much that configuration. My personal opinion.
But if you heard this circuit sounds and you like it just like this, then fine.
Tell me if I forgot something or there's something wrong.
The LED wiring in this pedal is not as we used to do usually. And I wired as we usually do. You can see the 4.7k resistor between the 9v and the LED+. The standard method.
Don't forget to update us about this building, if you're building it soon. I found some demo of this pedal, and it sounds cool.
(You can jumper the 3.9k if you find it too much bright, or just to try it. Or, maybe, you can add a small cap, 50-100pF, between K9 and M9 to cut some treble.)
