Hey y’all, I’m new here and just have a silly question- why all of the film caps?
I’m kind of new to guitar pedals, I’ve built about 3 pedals over the past decade but in the past 2 months I’ve built 4 from PedalPCB; I’ve got to say I’m hooked! Since 2016 I’ve built about 150 eurorack modules from panel/PCBs and have a relatively large stockpile of components.
The wisdom I’ve interpreted from the eurorack world is to use MLCCs for bypassing and film for any timing/oscillators/audio path stuff. If you have to use an MLCC for any typically film cap application then get a C0G/NP0 MLCC.
What has really spurred my question is that I’m building a low tide mini at the moment and the LFO/random board seems to call for film caps (after consulting the low tide documentation) for power bypass purposes. 100nF film caps between power and ground near an opamp, microcontroller , PLL, etc. Why not just use MLCCs for that application? After noticing this and looking back at my previous builds I noticed that some of the 100nF caps I had used were just power decoupling caps and nothing in the audio path. In any eurorack module I would just used a decent ceramic cap, probably something with an X7R dielectric.
Any and all wisdom is appreciated and thanks in advance!
