Can someone please help me, my Crybaby 535Q has stopped working, when i press the button and activate the wah, u can hear that there is a change in tone, but when u rock your foot up and down, there is no wah, i dont know wat the hell is going on??? i opened it up to see if something inside (a wire or something) might have broke and everything seems fine, the only difference i notice is that there is no yellow fluid on that motor thing, there used to be yellow fluid, now it seems as tho it has faded. I dont think the batteries have anything to do with it cuz u can hear a change in tone which means its working, but when u rock ur foot it doesnt change. can any1 please help
