The Solid Metal Dual Vacuum Tube Distortion Pedal from Damage Control produces massive gobs of face-melting gain. The flexible control layout lets you dial in metal tones from the 1980s to beyond tomorrow. The unique shape of the Bass control adjusts the speaker's resonant response for the proper level of chest-thump during tight palm-muted passages, while the Scoop feature allows you to dump mids and automatically adjust speaker resonance. The Treble knob sculpts and tops off your tone to perfection. Use it in front of an amp to add an additional hot-rodded amp channel!
