Coil Cut Mod for 1 HB Only

[vandyman]

Hi all. New member, I am.

Doing some mods to fix a defective 'Push-Pull' pot, or may have been a wiring mod gone wrong from my local guitar tech.

Here's the goods: ;D

89 Vandenberg (pro mod for 2 HB)
Bridge P/U: Seymour Duncan JB
Neck P/U: Dimarzio PAF Pro

1 Tone Pot (push pull) / 1 Vol Pot

What I'd like to do is to install an SPST switch to accommodate a coil-cut on the PAF Pro (neck P/U). I'd like to run the two coils in series when the switch is closed. However, when the switch is "open", I only want to run one coil in "series" (there is no other way right). The only schematics I've found show a coil split for two hums, and the schematic sent to me by Dimarzio tech support doesn't really match the one from their website (by the same description). I want to stay with an ON/ON switch (a 2 position) for the coil tap, and NOT a 3 position.

BTW - replacing the Push/Pull with a 500K "regular" tone pot.

Could someone provide a "link" to a previously posted schematic or explain to me the "would-be" simplicity of this modification??

Much appreciated.

Hi, and welcome to the forums.

According to the chart of color codes at....
www.ampge.com/SKGS/sk/Pickup%20color%20codes.htm

... all DiMarzio humbuckers have the colors

Blk(-)-----(North)----Red(+)
Grn(-)----(South)----Wht(+)

For a series connection Green would be ground, White and Black would be connected and Red would go to output.

The pickup could be split by a simple on-off switch connected between Wht&Blk and ground. When the switch was off it wouldn't affect anything. When it was on, the South coil would be grounded on both ends. Only the North would be active.

Another way would be to connect the switch between Wnt/Blk and Red. When it was on, only the South coil would be activated.

Hope this helps.

hi Vandyman,

i'm gonna make some corrections to your statements.

not because i want to give you a hard time.

if you use the terminology correctly, you'll be more likely to get effective responses to questions you ask in the future.


when a switch is off, we refer to that as open (no connection is made).

when a switch is on, we refer to that as closed (connection made).

when you have only one coil, it is neither in series or in parallel.

it's just a single coil.

hope that helps.

and Welcome Aboard!
