One easy upgrade you can do to your Dunlop Crybaby Wah Pedals is replace the old Potentiometer with a new improved Hot Potz II. We will be using a Hot Potz II ECB24B super long life edition rated at 100K. Dunlop states you get about one million cycles before it goes bad, it's also sealed from dust and has a low noise operation which is a plus. The ECB24B is compatible with all Dunlop Crybaby wahs including the Hendrix wahs.
