Another guy that doesn't understand metal film/carbon film

[derpedal]

So I know that using metal film and carbon film resistors has its differences.  Different outcomes in terms of noise and sound.  What I want to know is whether I should use metal or carbon resistors in my zero point dual delay I'm working on.  Maybe someone with more experience knows what metal or carbon can do for a delay? Thanks

The higher the part count, the more important this discussion becomes. For instance, in a 4-5 resistor build (Fuzz Face) that creates a lot of distortion, it's not really important to worry about noise. However, in a delay where you're using 40 resistors, the noise starts to pile up.

The Zero Point Dual is a high resistor count build that requires a larger amount of fidelity because of the nature of the effect. In my opinion, using Metal Film will result in a cleaner delay with less noise. However, using Carbon Film for an occasional value that you can't find in Metal Film will not be a bad thing. Carbon Film resistors are quite low noise, and Metal Film has only a marginally better noise performance rating, so the difference is very small, and perhaps unnoticeable.

TL/DR: Use either, but Metal film is relatively cheap so you can get the better noise performance without breaking the bank.

I figured someone would tell me there's almost no difference but I decided to ask just to be safe. Thanks for your insight!

It's really carbon comp that you want to be wary of.

The tan ones sound better. They also taste better. But you have to make sure the leads are clipped all the way off to get rid of that metallic flavour.

Apparently my dog thinks so, because I definitely found a 10k that I had cut the legs off of in his poop. Toanz 4 days.
