One Control PERSIAN GREEN SCREAMER. This is a compact effect pedal that allows you to switch between a Tube Screamer and a transparent overdrive. It has a few minor scratches, but it's clean and still a usable effect pedal. I am unable to lower the price for a while. Thank you for your understanding. - Brand: One Control - Model Name: Barking Green - Color: Green - Number of Knobs: 3 - Switch Type: True Bypass - Input/Output Terminals: 1/4 inch jack - Product Type: Guitar Effect Pedal
