I read, in the January 2012 issue of Vintage Guitar Magazine, that Doug Doppler gave him the Futura. They had a great interview with Joe and pictures of 17 of his guitars. Including his 1955 Les Paul, 1948 Martin 000-21, 1964 Stratocaster and the Futura.
futuras sell for anywhere from $2100 to 4500 ,they used to be the most sought after of the korina trio ,that is until EVH passed away and now everyone wants a destroyer , all 3 play incredibly well .the rocket roll sr is the least of the 3 but no slouch . i saw a destroyer selling for 9 grand recently ,and a couple of the v's for 2500 and 3500 ,but a futura hasn't come up for sale in years it seems ,i have 2 destroyers and 2 futuras myself and i would never part with any of them ,they will have to pry them from my cold dead fingers .
