re-Fret your guitar . . . . . the sky is the limit!
Try adding a few frets to your regular guitar to 'taste' these new flavors, or refret an entire blank fingerboard — your choice. AND, they're removable (the adhesive is on the back) , so you don't have to commit to a single system or tuning.
If we can hear over 400 notes in the octave, why in the world would you only want 12 frets? And why make them equally spaced? There is so much more melodic & harmonic color waiting to be explored.....
Pluckers have been moving their frets for over 500 years, but it has only been in the past few centuries that they were hammered in for good, and not necessarily in the best place, either!
