I am wanting to change p/u's in my wolfgang. I never play it because I'm not impressed with the tone. I changed the p/u's about a year ago with dimarzio air zone and air norton. They sound really muffled and too much low end. It doesn't do harmonics and tap harmonics really well at all. I'm looking for something with good harmonics and cuts well. Someone at SD recommended a custom and a jazz neck. Any suggestions?
