This is the MORLEY Maverick wah pedal. As a guitar effects pedal, it produces a unique wah sound. Operation has been confirmed with a 9V battery, and the exterior has no noticeable scratches or dirt, and is in relatively clean condition.

[Overview] The MAVERICK WAH is one of the pedal lineups proposed by Morley (USA), which has been loved by renowned musicians including Steve Vai. By using a light sensor (optical method) instead of a gear pot for wah variation, scratch noise is completely eliminated, and a powerful effect can be obtained without sound degradation. It is equipped with a switchless function that enables outstanding operability, with no on/off switch; it automatically turns on when stepped on, and the pedal returns to OFF with spring force when the foot is removed, providing excellent operability. Compared to the STEVE VAI BAD HORSIE, it is one size smaller, so it fits well on a pedalboard. It sounds good even with a clean tone, but I think it will be even more effective when combined with overdrive or distortion, etc.
