I've been thinking it might be good to also have a cello around. I'm not talking about becoming a real cellist, I just want to make reasonable noise for folk or rock (which is all I do on the DB or BG anyhow, though I'm comfortable with the bow and making progress in thumb position). I could use a more portable instrument, too. I think I could pick it up pretty quickly because the tuning won't throw me off - I already have a BG that's tuned an octave below cello and have also played lots of other fifths-tuned instruments from mandolin to cello banjo. All I'd really need to do is learn the French bow hold and one-finger-per note fingerings. Or am I missing something important? Any thoughts or advice would be most welcome.
