My son is turing 15 and he wants to add a wah to his pedalboard. He plays through a SG Standard (He bought it mowing lawns.. took him more than a year.) He plays hard Rock, Judas Priest, Avenged Sevenfold, Dio.. I would like to get him a decent wah (under 150 dollars) that is not noisy. I own a Budda Budwah .. which i like and I don't really know anything about other wah's. Which direction do I go? Dunlop Crybaby? Which one?
