Just finished up putting a set into a P with Jazz neck. Went the extra mile and lined the cavity with copper shielding. New pots and capacitor.
Not sure what pick-ups were in the bass before, but im a new believer in the P again. These pickups are GREAT. Used the .047 capacitor from warmoth as well as the CTS pots. The tone is exactly what lollar said it would be.
They wind these bad boys to early 60's spec. This bass sounds incredibly full now. Ive got a set of SDQP's in my other P-bass. They are quite mid-rangey in comparison to the lollars, which are considerably more balanced, punchy when you want, gritty if you want, mellow if you want. They do it all.
I was really impressed with the clarity playing at both the bridge and the neck with a pick or fingers.
Very reasonably priced set of magnets. Fit and finish are quite impressive. This company is proud of its work and you can tell.
