Joyo R-01 Tauren Overdrive Guitar Effects Pedal nails the classic emulation of a sought after low to medium gain overdrive guitar pedal at a great price. The Joyo R-01 overdrive pedal produces a warm transparent overdrive that adds dynamic gain to your signal without altering the tone of the guitar. It's a great pedal especially for a clean boost, transparent overdrive or a warmer more effected overdrive/distortion.
