(Used) Boss BD-2 Blues Driver

Key Features:

• Level: Controls the overall output volume of the pedal, letting you match your bypassed signal or boost the front end of your amplifier.
• Tone: Shapes the high-end frequency response, adding brightness and cut as you turn it clockwise.
• Gain: Adjusts the amount of saturation, moving from a transparent, touch-sensitive edge-of-breakup to a thick, fuzzy distortion at maximum settings.
• Power: Operates on a standard 9V battery or a 9V DC negative-center power supply (such as the Roland PSA-120S) drawing roughly 13–20 mA
