probably yeah, the loss happens from the fundamental design of a coil over a coil; the bottom coil "fights" the top coil and robs much of its output.
I agree totally. Yes, that is why I got rid of it then and now use a DiMarzio UltraJazz split coil instead on the same instrument - my custom fanned fret P-style bass.
On a similar note, I had a set of DiMarzio Model J's in a real '75 light ash bodied RW fret board J-bass in the early 80's that still had "patent applied for" stickers on the underside. Not because I wanted to, but at that point, the pickups had died a horrible death as mid-70's J-pickups are prone to do, and there was no way to get a replacement pickup out of Fender, and no reputable re-winders in my part of the country. (And the "money" frets were worn out and nobody regionally to re-fret the bass properly - so I sold it. I know where it is if I want to play it.) The Model J was about all the aftermarket that was available as a replacement pickup. Much ballsier than a stack. I liked them then, and I still have a set in another Franken-J now.
But on this bass, the reverse-P-pickup is a little farther upstream then "Fender Standard," and so is the J-bridge pickup, even proportionally a little bit north of the "60's" position. So the "polite" stack will have a little more string excursion to work with, and may fit tonally with the Nordstrand Mustang. Yes, the bridge I have put on it has a 2 1/16" string spread at the bridge; 2" over the J-bridge pickup, and 1 15/16" over the reverse P-pickup. Too bad I'm not an EB-3 fan: that would be perfect for an EB-3 setup! But that would entail a bunch of routing out and customizing pickup surrounds to cover the P & J routs. But I did think about it.
Thanks for all your comments.
