Worth checking.
You might also want to look into a good noise gate while you are at it, if you don't already have one! Apparently the one I've got (ISP Decimator G-String) handles the 60 cycle hum of single coils pretty well. I dare say the hotter you go the more noises you have to deal with, especially if you have a 'metal' amp. It cuts out pretty much all of the awful hiss and other noises that my Peavey makes without it, with the dial set around 11.30-noon
