Early 70's Space Age look 2x12 tube guitar amp. The SG Systems amps were made at the old Standel plant in El Monte, California in 1974 when Chicago Musical Instruments (CMI) purchased Standel. Back in '74 CMI and Gibson were owned by a company called Norlin. I called Gibson customer service they emailed me the schematics for this amp (included with amp).Model SG 209. Pretty rare amp and is considered the Edsel of guitar amps (cool retro design, but largely ignored). The amp has two channels. Channel one has volume, treble and bass controls, and hi and lo inputs for guitar. There is a master volume control knob with a red pilot light between the two channels. Channel two has volume control knob, reverb (controls the spring reverb unit), treble, bass, and wave form controls, along with hi and lo guitar inputs. To the far right there is a built in notch shift dial, a mid knob, and an accent knob, with “Dynamic Voicing” printed under this. On the back there is an on/off toggle switch, a standby toggle switch, a reset button, a 200w plug-in, and the power cord. There are also jacks labeled Waveform/Reverb, External Speaker, and Signal Line. It has a handle on the top and casters on the bottom. This amp is HEAVY. Everything works and you can dial in some great retro rock sounds.Not as loud as I think it should be based on its size, but great for bedroom volumes (too dang heavy to be hauling to gigs anyway).
From a non-smoking home. Let me know if you have questions. Local pickup only. I can meet in TC Metro area for delivery.
