And you are all set
I have an old Larrivee 6 string and I can handle about as many chords. I'm working on that finger picking thing and atr the risk of sounding like a braggart I will say I was blessed with a pretty good singing voice so there are evenings when I tune 'er up, stoke the fireplace, fill a glass, and whack away at it. I'm a John Prine fan so "please don't bury me, down in that cold, cold ground" is one of the tunes I start off with.
