    Are you wanting to simply have both guitars connected to the same preamp, possibly to expedite swapping between them in a live scenario?
    If that is the case, I would suggest one of these little "A/B" switch boxes on the market. Many companies offer versions of this in a convenient floor stomp box format. Proco, Whirlwind, Morely, ART, etc all offer their version of this box. While they are primarily designed to take a single input and switch it out to 1 of 2 outputs (like "Clean" and "Dirty" amps), these boxes are also able to do the reverse of that: take 2 sources and switch between them to go to a single output, in this case, your preamp.
    The operating impedances of most of these "A/B" boxes is such that it shouldn't load the pick-ups down. And the "active" versions won't "thump" or "pop" when switched.
    If, on the otherhand, you want to mix 2 guitars into a single preamp so that 2 players are able to perform simultaneously, you are running into multiple issues. You will have significant tone and level changes due to the improper impedance oading of the pick-ups. What you CAN do is get each guitar its' own prwamp and then mix them through a small (think Mackie 1202 VLZ) mixer. But you already knew that, didn't you?
