1-12" Maple Wicker Combo. In1 / In2 / Vol1 / Vol2 / Trb / Mas / Bas / Mid / Pres / Lmt / 5Graph / Haf-Ful / Stndby / Pwr. "Simulclass" logo & patent #s painted over. 1/2-fullpower switch instead. Huge magnet on speaker, no obvious brand. 2 fans. Reverb. 6-way voltage converter. Mic input. Mysterious switches w/abbreviated labels, that I'm scared to touch! "Son Of Boogie" back panel centered on top of the original back panel, lots of width on each side of it, seemingly to allow drilling custom inputs. Weighs 80 lbs. Front panel alone seems unusual,(8 knobs), since I can't find a photo of another one like it. Rumor is the 1st owner was in a Chicago band that had 'Mojo' in the name, and had another Mesa just like this one. What have I got here???
