I've bought a number of wahs including a Dunlop Crybaby 535Q, then had the pedal modified by Stuart Castledine (wah-wah.co.uk) then bought a Boss V-Wah PW-10 and also used my Korg Ax-30 G wah. I sold them all and finaly settled on a Teese wah, which I liked the best - a bit more vintage styled than the rest. I would go for the Picture wah or they also do a custom one called a Wheels of Fire wah, which I ended up getting. If you're on a budget, there's always the Dunlop Crybaby Original, which I heard a guy playing last night at the beer festival in Belfast!
