Stuff you wanted to know but were afraid to ask

C11 is going to get 18v, so 16v won't be enough. C22 is going to get 15v, but I still wouldn't stick a 16v cap there. I usually use 35v rated electrolytics in the power section even if I'm not planning on running higher than 9v, just in case I (or anyone) uses a 18v power supply on accident.

On the octave fuzz I'm guessing that the R6 and C4 are filtering out high frequency noise. Using a larger cap might make it sound like it's got a blanket over it. Someone else may have a better answer.

If it were me I would just order the correct components and wait to finish them as annoying as that may be. It's better than getting it done later and wondering if it sounds right.

While you're at it, be sure to buy spares because chances are good you'll use them sometime soon. Most vendors offer quantity breaks and there's the cost of shipping, so buying extras is a no-brainer.

on the octave fuzz r6 and c4 form a RC Filter ... so you can use a different cap if you compensate with a different resistor too otherwise you are going to be playing with the tonality of the pedal for good or bad

on the electrovibe, keep in mind that the values there provide filtering for the 18 and 15v supplies ... you don't want to go lower (noise potential) and I don't have a good handle on what the upper limit should be on going larger at 2AM on a Monday morning. you could probably get away with 220uf but I wouldn't be surprised that there be monsters I didn't consider

okay thank you, what your saying makes perfect sense on the octave fuzz. i'm breadboarding it as i type this, so perfect time to screw around.
Yeah on the electrovibe I was kinda guessing that so i got 50 of them coming at 25v to backstock. thank you!
