Thinking about Otis Rush's sunburst Stratocaster we see him posed with prior to 1963. Is it a '54, 55, maybe an early '56? It has a round string tree which would indicate an earlier model. Does anyone know what happened to this particular Strat? Otis Rush probably used this Strat for the Cobra Sessions and the Chess sessions that make it onto the 1970 release Door to Door which I believe was comprised of singles recorded in '60 or '61. The Epiphone Riviera didn't exist yet(or at least the model we see him with later). The other early Otis recordings I can think of are the ones on the Chicago/The Blues/Today! Vol. 2 record. But he may have had the Riviera by then. It sounds like a Strat to me but you never can tell.
