This is the Ray Drive overdrive pedal from HMPF Handmade Pedal Works. I am selling it to organize my equipment. I used it on my pedalboard, but it has no noticeable scratches or stains, and it works perfectly. Overview: An overdrive pedal made with reference to the circuit diagram of the VEMURAM JanRay. A distortion pedal with a wide range of tone adjustments with Bass/Treble and Saturation. Equipped with a saturation knob. The op-amp uses the optimal one compared to the actual machine. Current consumption is about 3mA. [Condition] No noticeable scratches or stains [Supported Voltage] 9-18V Thank you.
