How about a set of bluegrass instrument accessories? You could consider getting your friend picks for various instruments or a new capo. Alternatively, you could get them a collection of bluegrass records, or one from their favorite artist. If they're musically inclined themselves, a bluegrass songbook for guitar, banjo, or mandolin would be a thoughtful and useful present. Lastly, if you want to go all out, you could check for local bluegrass performances and surprise them with tickets to a show!
