I have a crybaby wah, it's 3-4 years old and it started making a crunch noise mid-step. It first did that after I hadn't played with it for a few months. It was alright at first but now the crunch is just annoying. What could the problem with it be?
the sound comes from the amp, it's not a physical crunch in the pedal.
You have to open the pedal. There is probably hair and lint in crap on the gear that turns the tone pot. Clean it off. While you in there spray some contact cleaner in the pot. Presto!
