This is an original overdrive pedal from SIRVERZ EFFECT, a well-known Japanese handmade effects pedal manufacturer. Based on a wide gain range, it's possible to achieve a broad range of distortion with two types of clipping modes. Used only indoors, there are some minor scratches on the bottom. (I am selling this one because I own two.) 【Specifications】 ・True Bypass ・Controls: VOL, GAIN, TONE, Clipping Switch ・Dimming Trimmer (on internal circuit board) ・Power: DC 9~18V (center negative), 9V battery ・Current Consumption: Approximately 10mA (when powered by 9V) ・Included: Instruction manual ・Power adapter and box not included ・Marble color
