Hi folks, I'm trying to branch out musically (is it evolution or devolution?) from banjo to ukulele. I have an amazing, one-of-a-kind open back banjo, half-fretless with a Tubaphone tone ring. The instrument is as beautiful as it sounds. The market value is around $1400, and I'd love to trade it for resonator uke of equal value. I'd be happy to provide photos, or sound clips.
