250K vs. 500K
Generally, 500K-ohm pots are used with humbuckers and 250Ks are used with single-coil pickups. You can use any value you like, but a 250K will give a slightly warmer tone than a 500K pot. The 250K pot bleeds off (attenuates) some of the high frequencies to ground.

Shaft diameter 6mm split shaft, coarse knurling
Thread M7 x 0.75
Threaded portion 3/8" (9.52mm)
Required mounting hole diameter    9/32" (7.14mm)
Flat washer and two mounting nuts included

not bad

If you need something that CTS doesn't offer then these will do. They are pretty sturdy. Make sure to clean and scrape all soldering surfaces prior to wiring for a clean signal since these come with gunk on them.

Blend Pot

I used this Blend Pot as part of a Gibson L6S Rewiring project....I put a 6-position Varitone switch in place of the troublesome L6S 6-way Pickup Selector. This left me with the choice of modifying the body for a new 3 way pick-up switch or finding a switch that would fit the tone control hole (I no longer needed the tone control with the Varitone).....the Stew Mac Blend Pot did the trick, plus now I can pan between the pickups, giving me more tone choices....also Stew Mac has a matching speed knob so no one would know that mods were made to the guitar.

250k pot.

I really liked the 250k pot I bought here. It's movement is stiff, but really quiet and smooth, like a well oiled machine. This means it'll stay where you put it. The center detente is easy to find.

Nice P/U Option

This is a really nice option on your guitar because it allows you to find the sweet spot for all your main fret work. Was a little noisy but 2 quick blasts with the electronics cleaner with swift complete rotations and all quiet with unique tones depending on the differences between your bridge and neck P/U's.

Which Direction?

When you install these I had to guess which way they go, and I got it wrong. so here it is.
As noted in the wiring diagram, source A is full on clockwise rotation, and source B is full on counterclockwise rotation. I hope that helps somebody.
Oh and they sound great, I used one with active emg pickups, and they work perfectly, once you get them the right way round.
