what exactly are hipshot tuners? i've read adverts on them, and all i know is that they are supposed to tune the strings more precisely...other than that, i'm clueless on what the point of these tuners are. edit: oops. i guess this should be moved to setup and repair... edit2: after doing some more research, i'm guessing that hipshot is just a brand....but, what the hell are hipshot extenders?
From the site. It's a switch on your E string tuner that can be "flicked" to lower your E string or "un-flicked" to go back to E.
