I've had 4 issues with pedals I've sold over the last few years: one guy mentioned after sending it back he'd "accidentally" plugged in a 48v AC power supply. one guy was adamant the wah I sent him was "noisy" despite me testing it at 4 different venues under a range of gear. After a lot of...

If you use an electro, follow that. If you use film, ignore it as it's irrelevant. Easy

If it was to JUST buffer - absolutely. That's also what that MOSFET is doing right at the start. I can guarantee there's a lot happening to the frequency response/harmonics from combining out of phase signals that go beyond just buffering though.

Probably imperceptible unless you were scoping for it.

Which version is this for? I'm just looking at a v3 and it's miles out from all the dimensions I can grab from the build docs.

Is your kill switch grounding the signal or just disconnecting the hot?

Seems to be a situation of they look cool and are available in large quantities for pretty cheap.

Honestly, it's not super important unless you're drawing a high proportion of the total device output - the difference in a few of the models I just compared was 1% voltage variation from 0-100% current draw for regulated vs 10% for unregulated (and the same from min to max input voltage). You...

If you've got voltage to spare (which you do), you can't beat a single Schottky diode for simplicity and minimal drop; 1N5819s cost nothing, drop minimal voltage and will withstand 40v continuous reversed all day. IMO, reliant on a RC filter these days on the power rail isn't that useful for...

Op-amps get biased to roughly half the supply rail - so you want the voltage divider to have two equal(ish) resistors for R1/R2 so the middle of these will be ~4.5v.

I use them exclusively for the workshops I run for beginners. A buck and a minute to solder is massively cheaper/easier than trying to get new solderers to cut/strip/tin/solder multiple cables :ROFLMAO:

The easiest way is (IMO) make things modular as well as bullet proof - separate the sections of the pedal that will see the most abose (jacks, switch, pot) into daughterboards and connect them to everything else with JST-XH's or ribbon cables. If something breaks, swap them over in under a...

If you have 3D models attached to your PCB, export it as a .step file and import to your CAD program of choice. From there it's trivial to create a drill plan. If you don't have 3D models attached, then your best bet is exporting it as a vector image into your vector software of choice and...

That is exactly what I am trying to avoid...
