This is a BOSS MT-2 Metal Zone. I believe I purchased it almost 10 years ago, but I've only used it for about 10 hours. It was left out, so there are some minor scratches and dirt. - Model: Metal Zone MT-2 - Brand: BOSS - Output Terminals: OUTPUT - Input Terminals: INPUT - Controls: LEVEL, EQUALIZER, DISTORTION - Equalizer Settings: HIGH, MIDDLE, LOW Thank you for looking.
