I'm a little late to the party on this one, but there is other stuff you can still do with the push pull switch. If you're going to have it in your guitar, it might as well do something, right? Off the to of my head, you could use it to...
- switch one of your humbuckers on in any position so you have the option of using all three pickups at once or both humbuckers in parallel, a la lp middle position
-switch your hb's into series wiring for a gain boost
-switch between tone caps since you have both a single and two humbuckers in the circuit
-remove the tone or volume control out of the circuit entirely so the pickups run wide open
-phase reverse on one of the pickups
-switch in a passive distortion circuit
-master kill switch to turn your guitar off between songs
I'm sure there are a hundred other things the folks here could recommend or even a Google search might spark some ideas. Even if none of those sound useful to you now, wouldn't it feel better to not use it because you have that option, rather than not having the option? Besides, it might all of the sudden become useful just when you least expect it to. :icon_thumright:
