I'd love to have a thinline doubleneck, seriously.
And an old Dano 6 string and bass, but the price on those has gone completely stupid.
But my '63 Dano doublecut is maybe my desert island guitar, over a Tele even.
It's that acoustic electric sound, it's unbeatable. Next up now is my 335 Dot, I just rediscovered it after 2 years in the case, and again, that acoustic tone, I really get it now after playing a lot of pure acoustic for a couple years, and it's magic. It's really great because I can beat on it (unplugged)and it won't cause a significant other to go for the headphones like a big ol boomy D35 can... I've now decided I'm not keeping any solid body electrics. Teles, Strats, LP Special, SG, double neck SG, etc, etc, etc, can all go.
