Marshall designed overdrive and distortion.
Pedal works fine, no issues with it.
Has a control for: Overdrive or Distortion mode, Gain, Volume, Treble, Bass, Frequency and Contour.
The pedal is quite heavy and very sturdy. The controls are placed in such a way that activating the pedal should not touch them.
This is a true bypass pedal.
Can be powered by both 9V battery or a DC power supply with a negative centre.
Do note: if you rent this pedal it does NOT come with a battery, I wouldn't want to hand you a battery with it only for it to die right in the middle of your session/gig because the pedal has been sitting to long without use.
