I recently bought a Seagull S6 and have started playing the guitar again after many years. My right arm and shoulder are in an awkward position when I play and I am having a lot of shoulder pain. Has anyone else experienced this? Does anyone have any solutions?

One person suggested that I try a smaller guitar. When I played his Martin 00, it was much more comfortable. He suggested that any type of parlor guitar might work for me. I would like advice on which parlor guitars might be comfortable and have a sound maybe similar to my Seagull. I am hoping not to spend more than $500.
