I'm fickle... *grins
And I'm blessed with great guitars. Right now my #1 is my Martin XC1T. It's my pick it up and go guitar, especially in the winter.
My other two acoustics qualify as vintage, so I don't take them out into the howling winds and dark winter nights... I named this Martin: "Number 9."

The bass that I rely on most now is Raven, my ex-Squier "Rescue Bass" which I have rebuilt with good quality parts and gotten
set up perfectly... once again, I'm willing to take this one places that I'm not willing to take my old '66... harsh weather and
unknown venues ahead? I'll grab the Raven Bass. This one gets the job done, without fuss.

But I don't think the OP was really asking about acoustics and basses... was he?
Nobody else so far seems to have thought so. But these are just the instruments I grab when I'm headed far down the
road, to play gawd knows where, on a stage I know nothing about... These two are 'working man's guitars..." nothing fancy, no heavy
insurance policy... no pedigree, no binding, no nibs, no problem. Just excellent tone and playability, and the ability to stand up to
unknown conditions, and predictable weather tantrums. If we're going to be part of a larger program, where quick change over is
important, or if we're going to play on a small stage I've never seen, I can play a whole concert with only these two,
and my bass amp and my "acoustic' pedalboard.
But if we've got a chance to spread out a bit, and if we've got time to set up, I'll bring my beloved SG special as well, and
have three guitars onstage. This is Luna in action:

She's the Queen of my music room, and the best guitar of any kind I've ever played.
I dally with other guitars, but she's my number one. Think of #9 as a Knight, and Raven
as a Bish-hopper... They venture places the Queen must not be risked.
