Models included a bass version as well as a PA system. Designed by Bob Crooks of Standel fame and manufactured by CMI ELectronics (Chicago Musical Instruments - former parent of Gibson - later to become Norlin Music) in Crooks' old plant in El Monte, CA. SG Systems amps had a hybrid tube power section and solid-state preamp with two extremely rare RCA 8417 power tubes and an RCA 12AX7A (the latter is possibly a phase inverter, driving the two power tubes, similar to the early MusicMan amps, which had a 12AX7 phase inverter between the solid-state preamp and the power sections). 100 watts, two original 12" speakers.Asking $200 obo Email or text if interested. Has original Maestro footswitch phaser pedal. In good condition, rolls, its heavy about 80 pounds. The Phaser effetct was built into these amps and the Maestro pedal would control it. This one is actually one of the smaller versions of this amp - it only weighs 80lbs (?!) - they have another version that has 3 spekaers that clocks in over 130 lbs!! Some of these use the 8417 output tubes which are sort of Industrial KT88's - I am told they take very high plate voltages and can run hot for long periods. I've posted these CMI amps before - they are really sort of "over the top" in design which gives them a rather mad scientist / Industrial design look. ![]()
