i've had a 00-21 style made a few years ago.
really nice sounding guitar, great player, but
don't know why, had the neck width made 1 7/8, with a relatively low profile neck shape.
always felt it was too wide too handle and after coming back to it after a year or so, definitely feel it's too wide, by up to an 1/8th.
it's unbound.
how invasive is making it narrower?
last thing we want is to wreck it....
