Since I've been practicing a lot lately, and getting much better than ever (for me anyways) I noticed that I've got some buzz going on that I think has to do with me picking too hard... For example, I'm playing Tennessee Whiskey, chording away, no buzz or anything. Move up the neck to do the solo part, and I've got some buzz going on. If I lightly pick, no buzz, if I play the way I "normally" would, I get buzz. Is this me picking too hard? Is there an adjustment to the guitar I need to do such as neck relief/string height? Thanks!
