EMG 25K Pot Good for Spin-A-Split, Yeah?

I'm working up a new pickguard for a new build.
I'm going to use a Spin-A-Split on the neck pickup (Fred).
The bridge is going to be a Gravity Storm bridge.
I read an older post by Clint 55 that recommended a much lower value for a better tapering effect.

The pickguard will have a master volume and tone and the S-A-S pot.

I have some EMG pots at 25K laying around.
Would that be a good recommended value for a good Spin-A-Split taper effect?

Yes sir. You must convert it to a no load pot tho. Otherwise the pickup will never be in full series. 25k no load pots will get you right into split-ish souding tones as soon as you turn it down. While 50k no load I have found to give the most gradual taper from full series to full split.
 
If you're doing it that way make sure it's wired as a rheostat and not a voltage divider, otherwise the low resistance to ground will just cut off most of the signal from one of the coils. I use hard wired partial splits between 2.3k and 6.8k, so I'd actually recommend using a lower value pot, somewhere in the 10k range.

How exactly will the guitar be wired in terms of potentiometers and switching? In general I find having a spin-a-split on a guitar is much more useable, especially with lower pot values, if you use a switch and a pot in tandem.

I figured it was just easier since I have the 25K's lying in a drawer already. Can I add a resistor to it to 'make it' a 50K?
Thanks for the No Load reminder.

Neck Pickup > S-A-S > switch > Master volume/tone
Bridge Pickup > switch > Master volume/tone

Probably using a Schaller 'E' model megaswitch wired for 2 HB's.
I have both 'E' and 'P' megaswitches here.

I use hard wired partial splits between 2.3k and 6.8k

You mean you use two resistors (those values) hard-wired to a mini-switch to give you two pre-set 'points'?

Yeah. I just take a pot and play around with it until I find the spot that sounds the best, measure it, and then find a resistor closest to that value. Having a potentiometer to control a split is a fun thing to play around with and makes the instrument more versatile, but I generally find that there's one setting that sounds the best and after I find it I don't usually adjust it all that much
