I got the NP5 from Carey about a week ago. Very cool looking with the angled pole pieces. I took apart my Geddy Vee, Routed for the P pickup and made a new pickguard for it JUST to try the p/u out. I compared it to the NP4 in my Blue P bass. Both basses have the same wood selections (Swamp Ash body with maple/maple necks) so I was able to get a good comparison. The NP4 is a lot brighter and much more aggressive. The NP5 is nice and warm but not at all muddy. A few months ago, I sent the Blue P to 2 TBers for a review and they both started that the bass was very bright. If the NP4 sounded like the NP5, I think I would of gotten rave reviews on the sound of the bass. I brought the Geddy Vee to work and I compared it to a Sadowsky P5 bass. This time, the Sadowsky bass had an Alder body w/ Rosewood board. The Sad. p/u had a bit more emphasis on the high mids where the NP5 was slightly deeper sounding with a little less out put. My over all impressions are that the p/u is AWESOME!!!! I'm going to build 2 basses with the p/u right away (Both PJ5's), one for a customer and one for Stock. I thought to myself, it doesn't matter what I thought of the pickup. I called Carey and offered to ship my bass to him so he can give a listen to the pickup and make any tweaks he may feel it needs. After all, he has to be happy with it before me. I personally wouldn't change a thing.
