Fly Pickups (Gen 1, Gen 2, and Other)

[Jayrod99]

Anyone know what size hex wrench fits the adjustment screws on the Seymour Duncan pickups on a Fly Mojo?

[rmora88]

Looks like a T5? Hex? I could be totally wrong...

Do the Duncan’s have a hex screw?!

Mine have a flathead slot:

Are you referring to the DiMarzio pickups?

+1 to VJ’s question. Only the two generations of Dimarzios had hex pole pieces; and they’re imperial 3/32” (same as other hex Dimarzios). The Duncans had either one or two rows of fillister flathead screws, depending on era of production. Note that it is simple to swap screw types between pickups if desired; as the bobbins aren’t threaded.

Will do—I have this info in a spreadsheet for each of my Flys, so I’ll get back to you soon.

Did you ever post your preferred height? I've got a Deluxe with Gen 2 Dimarzio and I'm trying to balance the bassy-ness of the neck pickup with the thinnesss of the bridge pickup. There is such a large tonal difference and volume difference that it is difficult to switch back and forth.

Ta da!

I've recently discovered that my '97 Fly Deluxe's bridge pickup is kaput and, in the process of trying to figure this out (thx again to all here who provided such valuable input), got some detail from Dimarzio that I had never heard before (and subsequent Google searches haven't really turned up these details):

• Dimarzio's code for the Gen1 bridge pickup is PHWB1 - note that this can be confusing as the Gen2's bridge pickup is PHWP2

• Dimarzio tech support tells me that the meter reads for Gen1 bridge pickups should be "The red/black coil should measure approx. 8.4Kohms and the green/white coil approx. 9.2 Kohms"

• As of this writing a replacement PHWB1 can be ordered from Dimarzio for $80 (before shipping)

I have an inquiry out to Dimarzio requesting the meter reads for the neck pickup (presumably the PHWB2) and will post them here if/when I get them!

This is great, @chrisjscott! Very helpful info! Thank you!

I had a brain fart in the other thread concerning the model numbers but, FWIW, the Gen 1 neck is/was "PHWN1." Each pickup has either an "N1" or "B1" position designation on the baseplate which is often hidden by the thin piece of mounting foam. I've also mistakenly referred to the Gen 2s by "B" and "N" designations when, in reality, it's as you said; with PHWP1 and 2 being neck and bridge.

I updated the original post with the following:

DiMarzio's internal code for the Gen 1 neck pickup is PHWN1 and PHWB1 for the Gen 1 bridge pickup. DiMarzio's internal code for the Gen 2 neck pickup is PHWP1 and PHWP2 for the Gen 2 bridge pickup.

Thanks @chrisjscott and @mmmguitar for making this thread more helpful!

Cost $80 + shipping; took about a 8 days to arrive.

Two things to note, for those of you who may find yourselves going down this route someday:

• The face features the current Dimarzio logo design, not the block one used on the original pickups (this is detailed somewhere around here. I actually THOUGHT, after placing my order, that I should've offered to ship the broken pickup to them so they could re-purpose the face so that my pickups match but "Eh. Not the biggest issue in the world."

• The replacement pickup doesn't include any neoprene foam underneath, so be prepared to re-purpose the foam from the original (or order more on Amazon - look for 1/8" thickness)...

Next up: soldering it back in without demolishing my ribbon cabling!
