Actually, I'm kinda with you. However, I see conversations all the time (not on THIS site, of course..:)...), that suggest that many bassist can hear the tiniest of differences. Just wondering how they do that....
For the record...this was my MPV5, 50/50 on the pickups, Flat on the tone, light gauge Elixer Nanoweb nickel rounds, played over the 24th fret: Trace GP12SMX/400SMX set "seagull" EQ, no pre-shape and the bass compression at 50% 60/40 tube preamp. 4x10 cabinet.
