Hi I want to buy a wah pedal that i can mod to give me volume control when i push a switch and also add some extr controls to? Can anyone suggest some pedals worth getting? I have been recommended a morley classic wah, is this a good starting point?

Wahs are a personal choice thing.  I like the Dunlop JH-1.  Nice tone.  Easily converted to a volume pedal.

I'd use an old Dunlop Crybaby or Vox. Certainly not a Dunlop 535 or whatever, as the pcb is full already. The recent Morleys don't have much room in the enclosure IMO.
