Whats wrong with my Jim Dunlop Crybaby Wah?

When I turn it on it doesnt sweep with the pedal it just produces one tone like its stuck in one position?

Remove bottom panel and inspect linkage to control shaft.
If the shaft is turning check wire connections to terminals of control.
If shaft is slipping and linkage needs to be tightened be sure that control will not be forced to turn beyond either extreme when linkage is aligned with and secured to shaft.

If control is frozen and and electronic lubricating spray does not help, a replacement control should be obtainable. Use only electronic solder to reconnect the same leads to a new control.

What's the model#?

It sounds like when you press your finger against the lead when its plugged in.
