if you can afford it, you can't go wrong with a crybaby or a morely. I can't, so I use a
Rogue Volume/ Wah and I really can't complain. I would just avoid auto-wahs. all the reviews about it on the site complain about buzzing and static, but mine only does that when its right by the amp. maybe my double grounded sheilded cable helps... oh well, works for me.
