So I've been working on my solo vocal/guitar set. I'm a singer first and not the greatest guitarist so when I go to do a guitar solo it sounds empty. I got the RC-3 so I can kick it on for a rhythm accompaniment during guitar solos. I've played with it for a couple hours. It has a bit of a learning curve but nothing too difficult. I think I want a second footswitch for added functionality. Anybody have some tips on getting the most out of one of these?
