I have a MIM Jazz with Dimarzio Ultra Jazz pups. It has plenty of highs and lows, but the mids could be fuller. I have Rotosound Swingbass 66s on it now. They sound good, but I'm still looking to improve matters. So far: Slowounds are too bassy and Sunbeams are too transparent, for lack of a better term. Fat Beams? XLs? Nickel Lo-Riders?
