Dimarzio pickup ID please

[ashbass]

I just picked up a '90 540Radius with HH setup and can't determine what the neck pickup is.

Both the neck and bridge are not stock (the bridge is a Fred) and both have 'Dimarzio' embossed on the bottom right corner of the top of one coil. The Fred is obvious from its model number, but the neck pickup has "S1" in the model number location. Other than that, it has the typical "Dimarzio Pickups - Made in USA" stamp. It also has a round faded sticker with an 'R' on it in ballpoint pen.

Has anyone seen this model before?

Here is the answer I got from Dimarzio customer service:

"S1 is the part number for the version of the PAF Pro (DP151) that is in
the neck position of an Ibanez JS1000. The only difference is the
chrome polepieces. "

Very sweet for me then
I got a 1990 Ruby Red 540R setup like a JS1000 for $240 shipped. It has the Paf Pro, Fred, coil-tap push-pull pot, treble-bleed push-pull pot, and a super clean black Edge trem.

Ebay has been very good to me.
