Did a search and didn't see this addressed head-on so... I'm thinking of trying new pickups in a KSD fretless 5 (the stock ones sound great, but I'd like to try some hum-cancellers). I love the UltraJazz in my '71 Jazz, but I'd like to see about other pups for this fretless. They gotta be hum-cancelling (preferrably in-line, like the DiMarzios) and fit in a Jazz case. Any thoughts?
