I bought these pickups as I already had experience of them when I had a Fender USA '62 Reissue Jazz Bass.
The units come with a pair of vintage style brass pickup shielding plates, which is a nice touch. The shielding plates have earthing wires attached, and have foam strips on the brass plate to allow for easy height adjustment.
The pickups themselves come with black covers, which are nice and smooth to the touch, unlike some sharper edged items. The pickup polepieces featured bevelled edges. These sit proud of the pickup covers. So, if you want the polepieces to be flush with the pickup covers, you'll need to insert a thin shim between the pickup tops and the pickuo covers. It's a very simple job, just use a thin piece of card.
As for the sound of the pivkups, they're really great. Very wide and open tonal range, with the classic "bark and bite" of the old Jazz Basses. As I menyioned previously, I have used these units begore onnother basses, and I was so pleased with them that I have bought this new set to use on another instrument.
The neck pickup is woody, with a throaty bark which, on its own, is almost like a P-Bass. The bridge pickup hasat bite which cuts through in a band setting. Both pickips together sound very warm, but still with loads of definition.
Grest price, nice touch getting the cavity shields, and the pickups themselves sound fantastic.
