On another thread I commented that the only pedal I use other than my Atomic is a wah (Dunlop 535Q) and that was mostly because I already had it when I bought the Atomic and simply couldn't be bothered to change things. I can't buy anything here in the Falkland Islands but I will be visiting the UK at Christmas so I've decided to make the change then. It's possible I may sell the 535Q privately but for the sake of simplicity, I may just trade it in to Rich Tone Music in Sheffield as I usually call in there anyway. They have suggested either a Dunlop DVP3 or a Source Audio Soundblox Dual Expression Pedal. I was initially thinking of something a bit cheaper like a Boss EV-30 but having never even looked at expression pedals before, I'm really not sure what's good value and what isn't. Any advice would be appreciated.
