well, while i was back in north carolina i bought a new acoustic guitar. Its an Alvarez RD8 sunburst. so far i like it and it sounds better than the other guitar i have. i paid like $220 with the hard case, Elixirs on it, and got some picks and an electric tuner thrown in. So i was just wondering if any of you guys have played one of these guitars or have any opinions on Alvarez in general. also i was wondering why it has a plce to adjust the neck. i'm not sure if you adjust the tension or what, but it came with an allen wrench and there is a place for it right inside the guitar. does anyone know what that is?
