What absurd, useless bass ideas dwell in the back of your mind? If I had money to burn I'd get a doubleneck bass with two two-string necks, both of them fretless and trem-equipped. Each neck would have three pickups with a separate volume knob for each. Pointy body, of course. And outriggers to keep the necks from flapping in the breeze. I know I'd only use one neck, one pickup and would never use the trem. Having no frets ensures the trem is even more unnecessary. And yet... I want this bass! So... how would YOU out-Spinal-Tap Spinal Tap?
