The only "feature" of the Hendrix wah is a lowered frequency range. If you listen to Jimi's wah stuff, it sounds like he turned the pot a little lower than normal.Hendrix never used any of the features that are in "his" Wah. He used a Crybaby.
Apparently the only difference between the Hendrix wah and a stock CryBaby is a capacitor changed in value to produce more bass response.
