'Partial' coil tap/split experience..

Re: 'Partial' coil tap/split experience..

You could just use a blend pot, which works exactly the same as what you are trying to do.

Thanx, but i already have a spare 25k pot that i want to use. Still not sure if i should cut the carbon ring inside the pot on the grounding side or the spare lug side to get no load so that the bucker is at full strength...

Re: 'Partial' coil tap/split experience..

If you can't switch it in and out then you'll likely want to go no-load.

G&L F100s do this with a toggle.

The spare lug side

The spare lug side

Thanks! I wasnt sure because when the wiper is on that side, i seem to getting the single coil only. As the wiper moves to the grounded side, it seems to go to full bucker. Maybe I just need to switch the wiring around. Ill try!

Re: 'Partial' coil tap/split experience..

If you're looking down at the resistive strip and you cut the left side, it'll go to no load at 10.

Then you wire it up like this:

Thanx! So you also agree that the cut is made on the spare lug side (left and right are interchangable depending on how you look at the pot)

No prob! Yep, that's how I do it to split as it turns down

Re: 'Partial' coil tap/split experience..

Has anyone tried using a Resistor or spin-a-split on the P90 coil of a P-Rail, to make the series humbucker mode less dark? I like the P and Strat modes, but the full humbucker is way too dark, especially in the neck.

I just want to thank you and everyone who helped with this. For the record, I used some left over 25k emg pots, one linear one log, and wired it up as mentioned above. I did the no load mod to both. It sounds amazing, and the 25k gives me an entire useful range. I would say that the linear seems a little easier to use but both are great. Much better than a 250k pot i used in another project. Note that the current spin o split diagram on the seymour site is missing a wire from neck volume pot to neck split pot (ground to ground).

Thanks again everyone!

Nice going! Yeah regular value pots don't work haha.

Re: 'Partial' coil tap/split experience..

reversed respect of "standard" (that is, shorting to hot, instead of ground, in an attempt to avoid some of the overall loudness being derived to ground)

Can anyone expand on this concept? What are the advantages of shorting hot instead of ground and why doesn't this short the circuit?

Appreciate background and common applications.

Re: 'Partial' coil tap/split experience..

If you short the red/white to ground you cancel the coil that has two paths to ground (for this example we'll say it's the slug coil) when you send the red/white to hot, you cancel the coil with two paths to hot (in this case the screw coil). All it does is change which coil is active when you split.

Re: 'Partial' coil tap/split experience..

Oh, I do that all the time- had no idea what it was called-
Much thanks!

Sorry to bump an old thread up, but is there any electronic benefit to choosing either shorting to ground or shorting to hot? Output, noise level, reliability, or anything?

Re: 'Partial' coil tap/split experience..

Shorting the red/white connection to ground (on an SD model) will leave the slug coil active, whereas if you send the red/white connection to hot it will leave the screw coil active. So the only difference it makes is which coil you split to.

I hope this helps someone. Particle split using newer style cts pots....Also included how to change volume pot to a 250 in the pulled up position. The value of r1 and r2 can be played with to tune to your own liking.

 

[Chistopher]

Crazy how when this thread was made I thought partial splits were the neatest thing ever because they made humbuckers sound like actual single coils.

Now I don't even like real single coils.

Still a pretty cool trick to have for people who want that option.

I decided to try the newer style cts pots. While I was looking for a diagram of the pot and also looking into different splitting methods I ran across this old thread. Seems there's alot of people wanting to do this but couldn't figure out how. I think it could be the layout of the new pot that some find confusing. No matter, plenty of people have shared with me on this site and others unknowingly in the past. Couldn't find a complete diagram anywhere for doing this so I made us one. My contribution to the community...Long live rock&roll

As of the end November 2022 I have just finished a rebuild of my Ibanez AH-20 Allan Holdsworth model. It was originally an HH configuration. The pots were dead and it needed some work. It already had an SD Allan Holdsworth in the bridge position (signed JBJ, from 1987 or so), so I got a brand new Jazz for the neck position to have a full pair of Duncans. Basically followed various diagrams to figure out how to split both humbuckers using new push/pulls, but the single coil sound was a bit thin. So went back in and added the resistors in order to make them 'partial' splits.

Now, this old battle axe has eight pickup configurations (up five from the old three configs).

1. Neck Humbucker
2. Bridge HB
3. Both HB

New:
4. Neck Single Coil
5. Bridge SC
6. Both SC
7. Neck HB, Bridge SC
8. Neck SC, Bridge HB

And they sound beautiful. Most interesting of course is when you use either pickup as a full humbucker and split the other one. Those combos add some spice and flavor to your playing. The new Jazz is such a clear and lovely pickup, and still heats up nicely when you want to blues shred a bit. As a bonus, I appreciate the original three pickup configurations more now.

Here's a sample of config #8 https://on.soundcloud.com/duL5B
