Q for wiring experts, JP wiring (diagram)

[apanboll]

Hi,

I have a question for you wiring experts.
I got two Caparison Dellinger.

On the first guitar I have installed DiMarzio CrunchLab/LiquiFire wired as John Petrucci.

Wiring diagram from Dimarzio


For the other Cap I've bought a Painkiller set. (Neck is not reversed wounded.)
What do you think of this diagram, will it work?



John Petrucci wiring explained:


Thanks ;)

As long as you just exchange the colors of the wire acordingly and have the correct switch, as this wiring does require a special 3 way after all, you should be home free.

Great!

I really enjoy JP's solution..  it's so versatile with few pots :)

[Kiichi]

I do really enjoy it too on the one guitar I have it in, which is currently still a LF CL combo, but as I am starting to grow weary of it (more comparison to BKPs) I think I shall within the year exchange the PUs and keep the wiring. Right now that even is my favorite position on that guitar as it is much more lively than the others, more BKP like if you will. Nice for cleans too.
Can of course be done with a push pull pot as well, which delivers 2 additional sounds as well, but I dig this one cause it is so pragmaticly simple in a way I like (normally I dig overcomplicated tonal options).
To bad that is my only HH guitar at the time, so the only one with that wiring.

Oh one thing about PU orientation though. YouŽll want to have the screw coils be the outer coils. Or to quote Felineguitars: "Usual orientation of humbuckers is that bridge wire exits bottom right and neck one exits upper left."
Definetly check the wiring before stringing the guitar up again. Just do the basic tap test (lightly tapping on the coils with a screwdriver to see if the correct ones are on in each position).

Ops, I noticed the neck thingy as well when I mounted the pickups.
Need to make changes in my diagram =)

Haven't owned any hb bkp neck-pickup except the sinner (which I didn't like)
The neck will be upside down.

Black = red
White = green
Green = white
Red = Black

.. to get it right I believe.

So you are not quite there coming from Dimarzio yet.

Red = Red
Black => Green
White = White
Green => Black

So basecally you just gotta swap the green and black to get it right.

sorry to spoil the party but one pickup needs its magnet reversing to achieve the JP result with all positions hum cancelling

That's no true!
I've had this conversion with dimarzio

Code: [Select]

4-conductor humbuckers can be wired in a number of different ways to
produce similar results. The connections shown are the same as used on
the MuscMan JP model that was built in 2009. It produces the same
performance as our standard wiring EP1111 diagrams that are also on the
site. It is necessary for the North coil of the bridge pickup and the
South coil of the neck pickup to be on in the middle position to cancel
hum.

There is never any need to reverse the magnet with pickups that have 4-conductor wiring. Reversing the magnet would also require a different diagram.

I meant when I flip the neck the connection changes!
To get ALL postion in phase my statement should be right.. or?

It is necessary for the North coil of the bridge pickup and the South coil of the neck pickup to be on in the middle position to cancel hum.

If you want the inner coils to be the ones that are on in the middle switch position to get the strat like sound that JP uses

The screw coil of a standard BKP humbucker has south polarity.
If you arrange the pickups with the screw coils nearest the bridge and neck like on a Les Paul etc then both inner coils will be NORTH POLARITY
You wont get the desired effect without reversing the magnet in one of the two pickups as both pickups will be the same polarity and you can't get the combo of pickups' inner coils in phase and hum cancelling

What Dimarzio allude to is that you could physically turn the whole pickup around so the inner coil's magnetic polarity is reversed anyway, but you may not want your screw poles to be facing inwards.

I've built enough guitars with this switching to know it's the case

[apanboll]

What you mean is that LiquiFire or CrunchLab is flipped?
That's why it's hum-canceling?

There's no screw-coils on dimarzio's CL/LF
Enlight me =)

What do you suggest me to do? Skip the phase, just wire standard as https://bareknucklepickups.co.uk/main/downloads/schematics/general/humbuckers/2_hum_1vol_push_pull_coilsplit_tone_3_way_switch.pdf

[apanboll]

Ahh.. now I get it.

Then my first diagram will work.
I flip the neck, the screw coils will be facing down.

When splitting the coils I'll have South (neck) and North (bridge)

Are there big differens in sound when flipping the neck coils?
