Im contemplating selling my 1950s M-1 Kay #22900 for financial reasons. The bass sounds great, is set up for orchestral performance. This bass is performance ready however, the bridge is set to my specifications so I would recommend an adjustable bridge. Have owned the bass for 14 years with absolutely no problems. The strings are brand new. It does have over 50 years of nicks mainly on the edges. It has a unique finish that always catches attention. Not sure if this is original because have not seen any like it. Now Im simply fishing for how much my bass can go for. Please shoot me an e-mail.
