M&V Guitars- NJ They ran a small ad in Vintage Guitar Magazine last month, in the back. I called and talked to them, and ordered it. Made in USA, huge .375" (3/8" !! ) AlNiCo single pole- 1 under each string. ( The link above takes you to a picture ) They were only $75, and they take PayPal. I installed it in a Fender USA 1957 P-Bass re-issue. The sound and punch are wonderful! I do not have to hit the strings as hard. They are quiet, too. ( 11K / 42 ga ) The best way to describe these- great P-Bass tone- just a lot more of it. And the volume string-to-string is REALLY well balanced. I can now hear runs up the neck on the two smaller strings with the same volume as the big strings. (!) I have had 6 sets of other well known pickups in this bass, and these are the kings. I JUST ordered another set just to have them around. I am a pro player in San Diego, and have been playing blues / rock for over 40 years. I've have never heard of these guys before, but at only $75 just took a chance, and I am flat-out impressed. ( I do not want to say which pick-ups came out- as the MFGs are friends of mine- but they don't make one like this! ) These blur the lines between passive and active pickups. Sometimes you just have to take a chance.
