I've had several DiMarzio P-90 HB's in the drawer for years, probably over 10-15 years.
So I had a project in mind for one or two which might involve coil splitting so I decided to ohm them out.
I have three of what I 'think' are DP164 DLX90's (discontinued) that all ohm out right around 10k.
They all have hex-head adjustable poles.
One coil is slightly over 5k, the other slightly under 5k, like ~4.5k and ~5.5k, for all three of them.
So there's that for a reference toehold in the sand.
I also have two DP162's, which are the DLX+ Necks.
Advertised resistance is 13.8k.
These had slightly unbalanced coils, ~7.6k and ~5.8k, both of them.
Then, this is the surprise and why I posted this thread, simply because there's very little info out there on them.
The DP154, the DLX+ bridge, gave me quite a surprise.
Advertised resistance is 17.28k.
It measured 12.2k (red/black/north) and 5.6k (white/green/south).
Wowza, what a difference.
Could you imagine someone coil tapping this thing with no idea what coil was doing what?
I don't know the whole line, or if there are others with this big of a coil differential.
Just thought I would post my findings, as I know these aren't very popular items and so very little info out there on them.
I would assume they were going for a more narrow sensing window (primary coil)
With the secondary coil doing nothing except acting as a 'shadow coil' to allow the HB'ing effect.
Or something...just guessing really.
