Ibanez GE-601 Graphic Equalizer
The famous '0' series , which gave us the Tube Screamer and the AD-80 was made from '79-'81 thanks to Mr. S. Tamura a senior engineer at Nisshin Onpa (Maxon). These pedals used electronic FET switching and had a solid square switch.
This is a six bands graphic equalizer plus volume +-12db
