An original Marshall 1960A<\/strong> from 1973<\/strong> is one of the most sought-after guitar cabinets ever, especially if it\u2019s still equipped with the rare Celestion G12M \u201cGreyback\u201d T1511 55 Hz<\/strong> speakers. The 55-Hz version delivers the coveted deep, woody bass, warm mids, and pleasant highs familiar from countless rock productions of the early ’70s.
\nThis cabinet is equipped with four original Celestion G12M 25-watt T1511<\/strong> speakers. The data codes 3x LF and 1x MF<\/strong> confirm that it was manufactured in 1973. Over the course of its more than 50-year history, a number of practical modifications have been made: The checkerboard wiring<\/strong> was replaced, the internal wiring was updated, two additional holes were drilled in the rear panel for optional speaker terminals (currently non-functional), and one speaker was recoiled. Some corner protectors have been replaced, and one of the four rollers is black instead of gold.
