I was wondering if there's a way of find out the "optimal" scale length. 650mm seems to be the most common length used, but let's say I'm getting a bespoke suit - how would one go about finding out the scale length that best fits me? Apart from trying out different instruments with varying scale length of course
Besides influencing the sound of the instrument, what are the effects of switching/changing scale length? More space for fingers, easier fretting? Is this always a matter of personal preference or are there ergonomic and/or physiological factors common to all players?
