I bought a used Fender Squier guitar to convert to microtonal and talked myself into stopping for a while at *fretless*. Surprisingly some fingering was pretty easy - as you can hear some octaves and fifths as well as the smooth, smooth slides and inflections.
Since the fretboard was a dark rosewood and the plastic wood I used to fill the grooves a bit lighter I have the normal 12 equal fret placements marked out for me - familiar territory as a stepping off point for microtonalism.
Caution - this is just noodling and not too far from 12 equal. This baby is only a couple hours old....
