Title: Bluesbucker vs Fantom P90
Post by: gregr on February 16, 2023, 09:00:09 PM: I’m not a fan of split humbuckers but will tolerate them when one coil is shunted by a resistor or in some cases a pair of resistors and a capacitor.

Assuming I would use one wired in series most of the time, why wouldn’t I want to buy a Fantom P90 instead and use a treble-peaker in order to get more of a Strat-style single coil tone out of it?

I recently saw a video on YouTube where the guy noticed a significant loss in output when splitting the Bluesbucker:

This doesn’t seem to be in line with what I’ve read about the pickup. Is he splitting to the wrong coil by mistake?

Post by: gregr on February 21, 2023, 07:45:16 PM: I read some replies and the guy said that he split to the screw coil. Is this the correct one?

I’m curious so that I can add that to the comment section in the event that he got it wrong. However, I’m really just bumping this because I changed the topic title.

I imagine this problem happens quite a bit since this is normally how people spit a humbucker. Hopefully the manual is clear about it,

Post by: darkbluemurder on February 23, 2023, 04:10:41 AM: This is what DiMarzio published for the Bluesbucker: https://d2emr0qhzqfj88.cloudfront.net/s3fs-public/diagrams/bluesbucker_0.pdf

Red/Black is the screw coil. If you connect black/white to red (assuming red is connected to hot) you would short the screw coil. If you use red as hot you need to connect black/white to ground.

If you use green as hot (e.g. because the BB is out of phase with the other pickup on the guitar and the phase cannot be reversed with that pickup) you need to connect black/white to red, which may not be possible with all wirings. Instead you can also connect black to hot, white to ground and red/green to ground as well.

Good luck,
Stephan

I take it the screw coil is also north in polarity?

Post by: darkbluemurder on February 24, 2023, 06:18:29 AM: I would have to check that. All I can say is that I never flipped the magnet in mine.

Post by: gregr on February 24, 2023, 10:23:04 AM: If it’s south then the wire colors on each bobbin would have to be swapped internally relative to the wind direction in order for the pickup to be in phase with DiMarzio’s standard wire colors.

Either way they do it (polarity or phase) really doesn’t matter, I’m just curious.
