VINTAGE MESA MARK II
The Mesa Boogie Mark IIB appeared in August of 1980, built till May 1983 and was the likely first guitar amp to provide a tube buffered effects loop.
Hand built, production reached about a thousand amps a year, so while the sales volumes never reached the levels of companies like Fender, the Mesa Boogie Mark Series amps were extremely popular. Ultimately they were superceded by the Rectifier models. Based on the production and serial numbers, this particular amp was likely built from 1980 to 1983.
The Boogie Mark IIB is switchable between 60 and 100 watts. Four of the pots have pull functions. The Volume 1 is Pull for Bright, the Treble is Pull Shift, Lead Drive is Pull Lead (ie enable the Lead channel) and Lead Master is Pull Bright.
This amp has the optional Graphic EQ and matching 1×12″ Electro Voice loaded cabinet. Both are in very good, all-original condition.
