So I have an EPI ES 339 P90 that I enjoy and just bought a set of the new Mojotone Quiet Coil P90`s. I am going to make it a master V and master T layout---that leaves me with two unused holes--- any useable ideas for other two holes. Was thinking maybe two more volume knobs so I can blend in the other pickups when either in neck or bridge position.
Any other ideas......

Use one of the holes for a phase switch, and plug the 4th hole with a Nylon panel plug.

Or simply install a dummy push-button switch instead of a plug. That way if you clam on a solo, you can exclaim, "Sorry mates, I accidentally hit the 'suck' switch on that break." Then click the button and count in the next tune.

I once plugged an extraneous "pot hole" in a pickguard using a large stainless steel cup washer; stainless steel countersunk flathead machine screw; lock washer & nut.

That may be a difficult task in a hollow-body though.
Beyond that, I got nothin'...

How about a combination of your idea and Peegoo's. One hole could be a blender pot for balancing the pickups in the middle position, and the other could be a phase switch.

I'd see if I could use a push-pull for the phase switch to keep the knob and the original looks, I'm not a fan of switches on guitars.

So what are the two tones like with a phase switch---
I guess explain the in phase and out of phase sounds?
Also on this guitar which I got for a steal of a price--in pelham blue----has the very common neck issue of very slight crack at each side of the nut---really slight and hard to see but it is there----how can I get glue into such a tight crack?

Way beyond my skillset, but maybe some kind of secondary under the bridge acoustic pickup?

That would be a good option--something like the Ghost set bridge--that gives you a fairly convincing acoustic tone.

Scroll down, then shop around.

Telewired, is the crack where the binding attaches to the fingerboard? If it's not major, I wouldn't immediately glue it as you don't want glue getting onto the back of the nut, it makes it more difficult to remove. I'd watch it for a while, and only glue it if it looked to be getting worse.

Here's a good youtube video about in phase vs. out of phase with P90's. The last comparison lick he plays starts to get close to the classic Peter Green out of phase tone, which is the main reason I'd do the mod.

Youtube video; short, clear, concise, good sound quality and no talking!

If your new pickups don't separate the negative from the shield, doing a phase switch will mean installing new pickup leads. Something to think about.

Blends and so forth load down the pickups a bit differently, so I'd stay away from them.

You could have a separate tone control for each pickup, too. That can let you use slightly different values for the pots if you so wished.

You can buy drop in Varitone switches that would probably fit. I'm not sure how they sound with P-90s though - I've only ever heard them with humbuckers, and variations in Strats.

so the project is done----I kept it super simple--just like me----one volume and one tone and a 3way----and I LOVE it.
