Gear for Guitar is a quality guitar podcast with excellent interviews, good discussions and thought provoking ideas. The hosts do a great job. My only criticism is that I can't find an email address for these guys anywhere. I'd love to send them some feedback.
I am one of 'couple of idiots' from that other guitar podcast the previous reviewer referrenced, so I know the work that goes into putting out a guitar-focused show. These guys are doing a great job. We need more guitar podcasts, especially good ones like Gear for Guitar, so let's all show them our support!
