Just a note, when I take the guitar to the sessions I don't use it to accompany songs. I use it to accompany the tunes, which of course are reels, jigs, slip jigs, for the most part. I think everyone has to find their own "voice" for their instrument - life would be dull if we all just imitated what famous people do. Some players can use the guitar mainly as percussion, but that's not what I do. My instrument is a classical Martin, so it has a deep warmth but is more harplike and fits an accompaniment style that follows the rhythm but is not another percussion drive - I leave that to the drums. There is more than one way to add a guitar to the session sound. It's a matter of taste in how well it works out.
