Samurai (Geisha Drive) Power Supply Capacitor

[Fingolfen]

I'm looking through the schematic for the Samurai (Way Huge Geisha Drive: https://www.pedalpcb.com/product/samurai/ ) and noticed something that seems a little odd. C1, which appears to be a power supply filter capacitor is 10uF on the PedalPCB board, but when I compare it to the Effects Layout version I've built before, that same capacitor is 100uF. Cross referencing with the Dirt Box Layouts version, it's once again 10uF. I've built the Effects Layouts version successfully, but I was wondering which one is technically correct...

Technically, if it’s powered by a 9v battery you don’t even need the filtering cap. 10u vs 100u wouldn’t make a real difference on the overall sound. Within the actual circuit? Possibly a huge difference depending on what that capacitor is doing in the circuit and where it’s located.

The Samurai was based on my own trace of my Geisha Drive.

10uF is what was in the original.

I don’t think that cap should affect the tone at all. It’s between Vcc and ground so it just filters noise from the power source. Since there is no signal at either Vcc or ground, it cannot affect the tone.

Technically, if it’s powered by a 9v battery you don’t even need the filtering cap.

It probably isn't even necessary if you're powering it on a DC power supply.

Any modern power supply worth more than 50 cents should have far more than enough filtering on it's outputs.

That settles it unambiguously! Thanks!!!
