LOL at the Pyramid. WAYYYYYYY back in the day, I had:
Pyramid PB700 Gold (Gold Series 1100 watts x 1 I think)(best amp I ever had back then, it was huge, popped several alternators!)
Pyramid Super Blue 250 i think (was good for being so small....)
Pyramid PB100 I think it was, I am not sure, it was small, black, funny looking, had push type (red/black, like your PB1100) speaker connectors and power connectors, and while it was playing music, if you played it without the speakers hooked up you could hear the music playing through the coils inside, was hilarious, little, dinky cheap amp...
Also cannot forget the Roadmaster 300 watt EQ's! Lit up NICE! And the old Sparkomatic EQ's, Pyramid EQ's and the pimp old Kenwood EQs (the long one and the short one, I loved the short one I had was like 5-7 band or so, was pimp...)...
Will post some pics of some old school crap at my shop....
