What's your "Bass of Doom?"
After playing for 35 years, and doing multiple recent fretless builds, it occurred to me, I have one virtually perfect fretless; A fender alder body P-Bass with a USACG thicker-than usual lined Indian Rosewood board, and a Fralin P-bass PuP. Tomorrow, I'll pick it up with the new 5% overwound Fralin J in the 60s position. I hope this PuP lives up to what the P does...Nothing really explains in total, why this fretless is more alive and stable and playable.
But when I really rip on it, I become a more expressive player. I almost become wild with it, with techniques and melodies I never attempt on other axes.
Have you got one of those, and what is it?
