If playing a wah-wah is important you probably know about automatic wahs that are available in stomp boxes or multi-effect boxes.Not the same thing but not bad (I've got one in a Digitech processor).I haven't had to deal with gout for 15 years but at the time I did I was prescribed naprosen sodium which is available over the counter nowadays as Aleve. It cleared up in a few days and hasn't come back since.I was advised to cut back on organ meats, like liver and kidney (which wasn't an issue for me) and dried legumes because they both contain purines and also to cut back on my alcohol intake, which I did. Good luck.
