look like the lower strings are a longer scale length than the higher stirngs probably to tune them lower or have them feel tighter for ryth playing

ahh now its start making sense .thanks
How do they even figure out how to make those things? Like, whoever designed the first fan fretted neck must have gone through a lot of trial and error to get the final result.

Of course, I'm totally naive and I don't even know how they figure out the fret spacing/scale length on a normal fretboard.
