After years of trying different jazz pickups I finally tried Dimarzio Model J. I put them low on my list having read they were too dark and you had to use 500k pots. I've found them to have quite a bit of brightness even with 250K pots and wired in series. They are bright enough that it caused me to double check the wiring thinking I might have wired them parallel by accident. Tons of grunt and heft yet with plenty of top end definition. I now get the same smile as when playing a Stingray. Maybe they are a particularly good match for my bass but I wish I had started there.
