Hey everyone, so I was thinking about coil splitting the other day and had the idea of just putting a volume pot on one coil. Its a pretty simple idea but I would need to do a bit to keep it sounding clean. Where as I thought I would have to find a pickup that had a click stop so I can cut out the potentiometer to stop any tone bleeding. Or I could use a push pull switch to cut the circuit out. Anything that would prevent it from being anything but full power when I want it to be full power. Any thoughts?

Not quite. That is the first step, which I have taken many times. I have coil tapped my Jackson, both my Ibanezes and my Aria. I just feel like there is something more I could unleash with the idea of coil tapping. Thanks for the link though, GuitarElectronics.com is a great site. I searched it for anything close to what I was looking for and they had nothing. I think I would need one of these. www.guitarelectronics.com/product/CPFNL11/Original-Fender-No-Load-Guitar-Tone-Pot-Split-Shaft.html Any thoughts? vF

I think a 250k audio-taper no-load pot (like in your link) would be an ideal spin-a-split control. But wire the pickup as normal, with the two coils joined (red/white if SD colours), then just use two lugs of your pot to bypass one coil, third lug disconnected. So the pot either fully shunts one coil, partly shunts it, or fully disconnects at 10 leaving full humbucker.
You can make your own no-load pot quite easily from a standard one.
Most of the tone change happens in the lower range of the pot resistance, which is why audio taper is best.
Another variation is to run the bypass through a cap, 0.022uF to 0.047uF works well. This gives the single coil highs and humbucker lows, and personally I prefer it on a bridge HB to a full split.

Yeah, that makes sense. You know of any good articles on modding a pot to be a no-load pot?
I'll probably stick to the coil volume. I have never liked what caps do to my tone.

I dont know of an article, but all you need is a full size 24mm pot. Prise the lugs up to let the back come off, and you can then remove the track. Just scrape gently across the track, at the end where the wiper is at the 10 position, until the end-to-end track resistance goes infinite (you can watch this on your multimeter, increasing scrape by scrape. Then reassemble carefully and press the lugs back down with long-nose pliers. It works fine, and is not a big risk since pots are cheap.
Instead of scraping, you can clean the track then put nail polish or super glue across one end to make an insulated section- Ive not tried that.
The cap idea is worth a test. It doesnt dull the tone, it actually brightens it compared to a humbucker.

Wow, can't believe I didn't remember how to do that. I know you or someone else on the boards had told me how to do that a few years back. Id rather have infinite resistance than 250kohms. There will definitely be a difference in signal bleed between those two values, haha.
I may give the cap idea a shot. Just install it temporarily to give it a test run.
Thanks for the ideas!

There's an easier way to make a no-load pot, most pots have an opening where the ends of the rotations are, take some clear nail polish and put it on the end of the full rotation. Let it dry and you have a no-load pot, no disassembly required. The credit for that goes to someone else on this forum, can't remember his name, the avatar shows a pic of him with a solder iron over a g'tar (iirc)

I've done two no load pots in recent months and just used a box cutter type thing. One quick slice and you're done.

Was thinking about this, if the pup cuts out at ten on the pot, would there be a volume change like going from parallel to a single pup with a pup selector switch? With a coil tap with a tone pot its different, wouldn't it better if the pup cuts out when you roll the volume pot all the way back?
Think you might need independent wiring on the two volume pots.
