Yes but that's multi-scale. Different than something like this

I just finished a multiscale. Not nearly as well executed as his but it plays very nice.

But yeah that has limited effect on intonation. For me I don't think I'll do it again, not worth the trouble. My spread is not as radical as his was.

@paulmcevoy75 Damn, that's a pretty back. And the grain on the neck, nice! What are those woods?

Thanks! Back is Chechen, neck is Douglas fir, headstock is Wenge and rosewood.

Multiscale works well on extended range instruments to keep string tension from getting wonky one way or the other. You usually see it used on guitars with a 7th string (or more) because the low strings can be pretty low tension without using huge gauges that can compromise intonation. It doesn't really affect general intonation though like true temperament frets (the staggered system pictured above) attempt to do.

I haven't seen a SelMac guitar built with TT frets. With the way chords are voiced and melodic lines are typically played in GJ I'm not sure it would really make much of a difference. Neat concept though, I'd love to try a SelMac built with them just to see what it would be like.
