This is a 1979 5200-1B PCB w/ Reticon SAD 1024A chip. It was upgraded with a barrel style power jack for use on pedalboards. A pedalboard power supply must supply 18V. The pedal also runs on 2-9 Volts batteries.
Truly on the fence for selling – for it creates a sound that no other pedal can do.
Airy, watery, flange and chorus; as heard on many classic albums.
Knobs are not original. It has some rust and wear, but works perfectly and was recently gone through by my tech to have
no problems for the foreseeable future.
