I'm proud papa of a new G&L JB-2 (jazz style) Tribute. While I like the stock pickups, I don't like hum. I've narrowed my choices to the Dimarzio Model J and the Bill Lawrence J-45. While there are plenty of soundclips of the Model J, there is hardly any of the J-45. Does ANYBODY have experience with each to tell me the difference between the two (output, tone, etc) and give a recommendation? I appreciate and thank you for your feedback in advance.
