I have them in my MIM Fender Jazz.
The biggest noticeable changes will be:
More tonal control: I.e a larger change in tone when adjusting pickup and tones knobs. More sensitivity.
Growl: You will get Growl, oh yes, you will get growl.
Output: A considerably higher amount of output. Not extremely hot, but certainly a nitceable amount compared to stock pick-ups
More Midrange character: Hence the growl
I say get em! I love mine ! Chuck a badass bridge on too, they are wicked as well
