I picked this guitar out because it wasn't a low end or cheap guitar. I wanted something with a little quality and the Martin's were just a bit out of my price range. I put brand new strings on it and ever since day one, I can rarely get through one song and have to re-tune. It seems to almost always be the 'G' and/or 'B' and sometimes 'E' strings that always go out of tune. I'm using strings made for acoustic guitars. Thanks,
Mat
