Successor to the Q1027, the Yamaha GQ1031 is a 31-band (20Hz to 20KHz) graphic equalizer that fits in a 1U rack. It can be used as a mono equalizer or as a single channel one when paired with another similar unit. For convenience, Yamaha also sold two of them in a single box with a couple more features as the Yamaha Q2031. An upgraded version, the GQ1031B, was released in 1987, followed by the GQ1031BII in 1988.

With a retail price of 200£, it joins a long list of yamaha affordable yet high quality products for home musicians. The sliders are fairly short but the circuitry is very quiet and everything works smoothly as expected.
