Thank you for viewing. This is a product that combines a MORLEY wah and volume pedal. I was using it fixed to a sub-effects board, but I am selling it due to the reconfiguration of the sub-board. It saves space on the board and was also useful for home recording, etc. It has been used very little and there are no operational problems. It is a sensor type, so there is no scratchiness, and the wah volume is also variable, which is convenient. Thank you.
