Ultimate Drive Effect Pedal for Electric Guitars with True Bypass Portable Single Guitar Pedal DC 9V Black (Standard)

Feature:
Ultimate Drive Effect Pedal gives you rich, bordering-on-distortion overdrive, surpassing what a diode tube amp can provide.
Open it up and you can find the kind of response and spacious harmonics of a big overdriven tube amp.
Three knobs are separately used to adjust the volume of the sound(Gain Knob), adjust the degree of distortion (Level Knob), and adjust the intensity of the tone (Tone Knob).
With the True Bypass design, which minimizes tone loss, to realize the original sound of your guitar.
Mode Button: the mode high has higher frequency than the mode low; LED can visually indicate the working status of the guitar pedal; powered by DC 9V adapter, convenient to use. (Power adapter is not included.)
