I don't get the " you've already drilled out the holes " part

Who installed those tuners? They're all over the place...my OCD senses are tingling.

An effective ad to make me not want it.

how could i live without that?? :O xD

can a lefty use this?

looks like a pain in the azz :) and all those holes in the back of the headstock OMG

Cool!
