Ok, guys, I’ve been googling up a storm tonight, and I want to try to get to the bottom of this issue about why we need such higher tension on longer scale instruments, and what to do about it. So, consider that bass strings have tensions in the 30-40 lbs range. And they STILL flop around against the frets more than a 11 lbs high E string on a strat. Now, I understand that the sheer length requires substantially higher tension. But can we not figure out an equation to help determine what that tension should be? We now stiffness goes down with the cube of the length, so that’s a HUGE drop in stiffness for a small increase in length. But we don’t have an equation to help pick a string thickness. Then, there’s the core thickness (hex or heavy core) that makes the string less flexible, allowing for a smaller diameter string. But wouldn’t that inherently increase inharmonicity? As a practice issue, I have a 30” guitar tuned to G#0, with a .142” Kalium. And it STILL feels too floppy. And I have an instrument at 32” that I want to tune to G#0, but I am not sure if the increase in scale length will make that .142” feel tighter, due to the stretching the extra 2”, or if it will feel looser, for that increased length. I’m looking at piano stuff online, because clearly that has been figured out (based on scale length issues and string diameter). But it’s heady stuff, and it’s not easy to slog through. Anyway, give me your thoughts. And @ixlramp @bostjan @Winspear get in here!
