Vintage 1971 Marshall model 1961 "Bluesbreaker" 4x10 combo, 50 watts with tremolo. This amp is super rare and super cool. The condition is very good. The grill looks great, with a few scuffs. The speakers are original with an offset 4x10 configuration. The tolex is fine and looks good. It works great, and it really sounds amazing. Eric Clapton used a four 10" model in the earliest days of John Mayall. A must have for the Marshall enthusiast!
