Edit: For some reason the buzzing sound I'm talking about is only coming through when I play this from my phone speakers, not on my computer.

Deleted previous post to reupload using a pick instead of my thumb. For a while now my low E string has sounded dull and I have been hearing a buzz that sounds like it's coming from underneath the saddle as opposed to buzzing on the frets. I don't think the action is the issue, although it's not perfect. I just changed the strings, Elixir Polyweb Custom Light 11-52. It is an acoustic/electric Martin GPCPA5K with an onboard tuner.

Sorry for the duplicate post, just realized the commenter was right and I should try using a pick. The buzzing is much more noticeable with a pick.
