I'm thinking of changing my stock Music Man pickup with a Bartolini. I was wondering if I could get some input from others who have done the same. Which model did you use? MMC, MME, MMX, etc.. I'm looking to add more growl, and to even out the volume over the strings. My E and A strings are considerably louder than the D and G strings. Way louder. Have any of you had this same problem? Did the Bartolini help?
