Dunlop Crybaby 535Q
I couldn't be happier with this wah pedal! It comes with some instructions on how to set the pedal like different artist on different songs, i.e. Jimi Hendrix voodoo chile, so it gives you a starting point and from there it's up to you it almost feels like the skies the limit with this wah, also the boost is a great touch.
Plan on spending a lot of time exploring all of your tonal options.
