I have a fairly new MIA Jazz bass with stock pickups and have been soloing the neck pickup and dialing the bridge pickup back (or cutting it out altogether sometimes). So, I'm obviously dealing with the 60 cycle hum thing, which sends shudders down our soundman's spine... I love the jazz bass sound, but have considered putting a set of hum-cancelling pickups in to eliminate this problem. My question is how drastically would it change the tone? I talked with Mike Lull just now and he recommended Lindy Fralin hum-cancelling pickups. He admits they change the tone somewhat, but says they are so close to the single coils that most people could not tell the difference (although he could hear the difference himself). Would you JBass players recommend going hum-cancelling or just going with a really top notch single coil (like SD AntiquityII or Vintage SBJ-1, etc) and living with the 60 cycle hum? As I was searching older threads, I saw the reviews of these and others (from SMASH) and seems like there are benefits to going this route as well.
