Allparts Push/Push Poti 500K

I used this with a set of 4-wire humbuckers as a coil split. They were wired with a 500k pot of the same shaft diameter by default.

Pros:
Quite easy to solder to the tabs
Reliable (the pot didn't gradually get noisy)

Cons:
The fully extended pot sticks out quite far from the body of the guitar
The locking washer is easily shaken loose.
Relatively expensive

Overall it's a good solution if you want to be able to activate the switch without having to grip the pot itself (as with a push-pull equivalent). It's fairly pricey for what it is, but there are few options for push-push pots.

I usually use push pull's on my guitars, but opted for this on my own personal guitar.

This is far faster than push pull, but sometimes a quick push can turn the pot a little, but I'm getting the hang of it.

My next P-P pot will be a boost instead of having foot pedals.

Its time I tried one, works a treat, OK, you cannot see (by looking) if it on or off, but I got all that sorted now simply by listening. Sometime I have to go & listen at my amp, but if we're doing a gig w'out the drummer I can hear my sound from the Mic position and it works well.
