Here's a video of Brendon Bayliss of Umphrey's McGee talking about the Korg PC-1 Pitchclip Guitar Tuner. This easy-to-read, clip-on tuner features a bright LED -- not LCD -- display that can angle up for clear visibility. The display contents can be reversed (or flipped) so that everything is still properly oriented when mounted on the back of the headstock, so as not to distract the audience from your performance.
Umphrey’s McGee may be the only nationally touring act deserving of the title "prog-rock jam band." A staple of the jam scene for more than half a decade, the band has made a name for itself by combining bold improvisation and a guitar-heavy “progressive aggressive” approach into their incendiary live sets.
