A 24.75" scale bass? Heresy, I say!
I've never done such a thing, nor ever felt a desire to do so. Am in the opposite camp of ridiculousness, my Epiphone Les Paul Standard bass is a full 34" scale neck grafted onto a regular, Les Paul body. Small body, daft long neck vibes. First fret is about an inch further away relative to where a P bass et al would be as a result. Feels very "rock" when playing at the first fret with that little bit extra reach required.
