I am thinking of buying a second instrument and could use some advice. I mainly play British Isles music or American music with Appalachian or country feel. I've been using an alternate tuning on my guitar and instead of constantly retuning, I've decided to splurge on a new toy. Does anyone have any comment on whether to go with another guitar, a bouzouki, or a cittern. I'm interested mainly in song accompaniment, with a little picking when no one's around. Thanks, John
