Bass: I have played a Chadwick Folding Bass since 2011. It has made touring with an upright bass possible. The Folding Bass is an invention of Charlie Chadwick, in Nashville, TN.
Bow: I use a Revelation, made by CodaBow. Excellent carbon fibre bows. They are based in Winona, MN.
Strings: I used D’Addario Kaplans. D’Addario is a great company based in Long Island, NY.
Luggage (essential musician gear): Osprey Packs. Amazing. Cortez, CO.
Huge thanks to all these companies for their enduring support.
