This pedal is a copy of a ProCo Rat.
A distortion sound which copies a Rat with the LM308 chip, yes it also has one.
Has controls for Level, Tone and Filter, on top of this it also has a switch for Vintage or Turbo mode.
The switch allows it to change to a regular Rat or the Turbo Rat version with more gain.
Perfect to see if you would want to get yourself a Pro Co Rat or even this copy of the pedal.
This is a true bypass pedal.
As its a mini pedal it should be easy to fit on a pedal board. But is also means it does not take a 9V battery.
Powered by a DC 9V power supply with a negative centre.
