This is probably a total novice question, but here it is anyway. Do any of you have a recommendation for greasing/lubing the pedal of a Wah? I have an old late 70s Crybaby and it’s my absolute, bar none favorite pedal. However, the old pedal has a super tight action. It doesn’t want to move freely and smoothly anymore. Have any of you had this problem, and what did you do to fix it? Any other pedal I would just crack it open and get to work, but I’m paranoid of doing something that would hurt this particular piece of equipment. thanks everyone.
