Yes,
I’ve done this a couple of times…
I start with 320 grit wet-dry sandpaper (dry) and carefully go up and down the edge, smoothing the fretboard edge and knocking down the fret ends simultaneously…once I got the shape (doesn’t take much at all), I then go over it a little with 800 grit…
That’s it…done…takes about 10 minutes…
If you want, you can protect your frets & fretboard by laying down some masking tape first, lengthwise parallel to the edge…I haven’t bothered.
The effect I work towards is a "worn" edge not a "rolled" edge per say...
and yes it does make it nice and comfy
