Re: Agile Multi Scale Guitar
It's more to do with keeping an even tension across all of the strings, as well as more accurate intonation. On my Septor the higher strings are very tight compared to the low B and F#. I could sort this out with different gauge strings, but a fan of say 25.5"-27" would do a similar job and carry more benefits. E.g the shorter scale length on the treble side makes for easier soloing.
I haven't tried it myself, but from what I hear anything under a 2" fan doesn't really feel much different to a normal fretboard. Plus it looks so damn cool
