Hard to find, Akai G-Drive (D2G 'equalised distortion') from their Professional series for trade. Swap for other drive pedals or a nice compressor perhaps?

Has two banks of 6-band graphic EQs one is pre gain the other post gain, the idea being you can boost/cut certain frequencies before the distortion to give it different characters, then shape the overall tone at the output with the 2nd EQ.

Its in good condition, just a few paint scrapes at the edges, but then they are built like a tank. Foot pads are non original. Pics show size compared to a regular Boss pedal.
