I scored my second Kay bass today, a 1955 Kay M-1B in terrific shape with a new ebony board and adjustable bridge. It’s a Kay boomer. Bob and Cody and the guys at the Bass Violin Shop did it up great. It has a set of Helicore pizz strings on it now and it sounds great but they have a bit too much tension for much me. I have always wanted a Kay Swingmaster but why think this will do for now.
