Oates (Rono Strings)
Based in Boulder, Colorado, Ron has built electric mandolins for members of two of Boulder's best-known "jam bands": for Leftover Salmon's Drew Emmitt, a pair of standard 8-string mandolins; and for the String Cheese Incident's Michael Kang, three 5-strings (one standard, one octave, and one baritone). Other Rono players include Lewin Barringer, formerly of Standing Wave, and Carter Gravatt of Carbon Leaf.
On the left are three of Ron's standard-sized mandolins: two 8-strings and a 5-string designed for Kang. On the right is a baritone-sized "resolectric." Ron is reportedly no longer taking orders.
