Seymour Duncan JBJ P90

[nevermorefu]

I found a Seymour Duncan JBJ P90 for sale, and I'm trying to figure out if it is legit; I can't find any information about it. Has this pickup ever been manufactured? If not, could it be a custom job? Here is the back plate:

Welcome to the forum.

I read the ID sticker as 1BJ. SP90-1B, Vintage for bridge/Treble position.

In my opinion, the J looks suspiciously like it has been added, after the fact, in somebody's handwriting.

Are you lurkers trying to find info about it too?

Ok. That makes sense. Thanks for the info!

Re: Seymour Duncan JBJ P90

For what it is worth, there are several similar model names that could cause confusion.

JB Junior = Stratocaster-sized, noise cancelling, high output pickup
JBJ = Old type model ID sticker found on SH-4 JB humbuckers wound by Maricela Juarez.
JB90 = Custom Shop special order SH-4 JB, physically altered to fit under a P90-sized cover.

I figured I'd take a chance and buy it regardless. $35 for a Duncan P-90 that has to sound better than the $18 Mighty Mite and the $10 Catriona P-90s I have. It's also hotter than my current P-90 (9.6k vs 7.94k).

I got the pickup and installed it. Definitely sounds better than the cheap ones I wasted money on. Here is a better look at the sticker. It is definitely a 1B or IB with a hand written looking J. It is 9.6k; is that too hot to be vintage?

Re: Seymour Duncan JBJ P90

On original Gibson guitars, both P90s would have been identical. In practice, this would tend to make the bridge/Treble position unit seem weak compared to an identical pickup in the neck/Rhythm position. The SD SP90-1b is slightly overwound to compensate.
