Details:

I have too much gear so am parting with this amp. Reverb and fuzz work. Both channels include separate oversized and easy-to-read volume, bass treble controls. The open-back cabinet is covered in lightly-grained black Rolex and the edges are clad aluminum angle stock with metal corner protectors giving cabinets look of an Anvil road case.

The effects channel adds Mid range tone and Accent controls, the latter being similar to an attack or presence control. A master volume knob controls the mix of both channels. Here is some info posted by a reviewer who very knowledgeable in regards to these amps. Rolex is very nice shape with one small imperfection as mentioned in the condition.

No rips in the grille cloth. Phase is currently not working. Model's included a bass version as well PA system. Great 1976 CMI Electronics Gibson SG Systems SG-212 Vintage 100 Watt Tube Amp.

Varied speaker configurations were the biggest difference between model's: 1-15, 2-12s, 4-10s, 6-10s, 2-10s 1-15. The grille cloth is black with a brushed silver and the speakers have chrome voice coils as an option, these amps could be ordered in blue denim cloth, Alec may been option. A heavy duty leather handle is installed on the top of most cabinets which roll large round casters. All model's had two channels, one clean and with effects, each inputs Hi Lo impedance.

Maybe an easy fix. SG Systems amps had a hybrid tube power section and solid-state preamps with two extremely rare RCA 8417 tubes an 12AX7A the latter is possibly phase inverter, driving the tubes, similar to early Musician amps, which 12AX7 inverter between sections. Is very clean and in fantastic shape.
