MOSKY BROWN High-quality Distortion Guitar Effect Pedal Full Metal Shell True Bypass

Features:
High-quality distortion guitar effect pedal with true bypass.
2 switches: Vintage/Modern Switch & Boost Switch;
--Vintage/Modern Switch: for setting the overall voicing of the pedal's frequencies, to be either darker with a classic tonality or brighter and more modern.
--Boost Switch: for altering the internal gain structure of the pedal to bring much more drive, heavier and more aggressive distortion.
4 control knobs: Tone, Contour, Volume and Gain;
--Tone: for adjusting the frequency emphasis on the highs. It interacts substantially with the Contour knob and Vint./Modern switch.
--Contour: for adjusting the frequency emphasis overall. It interacts substantially with the Tone knob, and is affected by the Vint./Modern switch as well.
--Volume: for adjusting the output level. There's plenty of volume on tap in either standard or Boost mode.
--Gain: This control, in conjunction with the Boost switch, lets you dial in anything from a classic, almost laid back early rock tone all the way to modern high-gain.
With LED light for indicating effects or bypass status.
Compact size with full metal shell, portable and durable.
