So I'm thinking about slapping a pair of these in my Peavey Grind NTB pretty soon. They're the kind that switch between dual coil humbucking mode and single coil "jazz bass" mode. http://www.emginc.com/displayproducts.asp?section=Bass&categoryid=27&catalogid=116 Anyone have any experience with these? Or know an online store where I can purchase them? Or do you have to call EMG up and special order them? These would be perfect for the kind of sounds I want, like 2 basses in one.
