So I want to do some simple pedal modding (diode swapping) in my big muff. My knowledge of pedals is missing pockets here and there. I know where to put everything and to go anode to cathode etc but I have a few diodes kicking around and can't figure out if they are germanium or silicon. From my research silicon can be either glass or germanium correct? Could I use the small place platic style diodes and would they sound much different than glass ones? Thanks!
