You have a Martin guitar, the action is high and not fun to play. You can restore the  playability and volume by having a neck reset performed. We are Cf Martin Certified and we do a lot of neck resets on Vintage and newer Martin guitars with great results. The neck will be steamed off, angle will be changed and in most casses a new taller bone saddle will need to be installed. This will bring new life into your guitar and you will notice more volume and improved comfortable action while you are playing.
