This is a relic of the past, where acoustic instruments had the max amount of tension applied to them for the sake of loudness. And somehow the same tension got applied to electric instruments, and solidbodies obviously can handle more tension, but it's totally unnecessary, and negatively affects the sound IMO. I have an old hofner bass, short scale, with TI flats, and tuned down a half step. So there is almost nothing wanting to pull the neck into a bow, and the truss rod is completely loose, with the perfect amount of relief. While this may not be realistic for most, the instrument just feels much better than almost any bass I have ever played, actually I will say better than every bass I have played. While the average bassist would call my strings loose, I don't see it that way. i see them as perfect, and everything else is needlessly tense. While I didn't necessarily knowingly choose this particular tension, other factors and luck got me to it, and I love it. I play other instruments, so I can't practice bass all the time, but when i pick it up, even after days of not playing it, no warm up is needed, I can play absurdly fast without getting tired. And I push it to it's limit, so i am still feeling the same amount of impediment/tension that most people feel, I am just able to go far past what I could do normally. And the hof being a small thin almost acoustic instrument, the decreased tension is perfect for it, and I would recommend lower tension tenfold for acoustic instruments, which are always being incapacitated because of issues often due to the tremendous unnatural amount of tension on them. I have been watching videos on baroque instruments, such as baroque viola, cello, violin, and they all just sound better to me, other than the gut strings, just more open, mellower, and more pleasing to the ear, because of the decreased tension. Instruments with too much tension sound choked and harsh.
