So a couple of buddies and myself are getting together next Saturday to have a Marshall A, B, C test. represeted will be 3 nice circuit examples of Marshall's history. #1 a Rocky Top JTM45 clone (early tube rectifier circuit) #2 a 50wt Plexi clone built by DaBeck in Richardson Texas. #3 an actual 1978 JMP 50wt head. we will try them in different cabinets (we have a 4x12 and a 2x12 Avatar with greens, also a 2x12 with some Eminence Red Coat speakers) We will have a few Les Pauls, Strats, SG and a Tele.... not to mention plenty of beer and BBQ! I will let you know what I find!
