The ARION distortion pedal SDI-1 offers a wide range of sound creation possibilities. - Brand: ARION - Model Name: SDI-1 - Type: Distortion - Adjustment Knobs: LEVEL, TONE, DIST Thank you for viewing. I used to use this, but I'm selling it because I haven't been using it lately. It has been carefully stored in a dark place, but it is a used item, so there is some wear and tear. Also, I haven't been able to confirm its operation because I don't have the necessary equipment. Thank you for your understanding. Type: Electric Guitar
