Built to summon the same searing overdrive and distortion tones as a certain pedal of a similar color but with improved headroom and stackability throughout the chain for a combination of effects and sounds, the Mad Professor Little Green Wonder Overdrive Pedal brings simplicity and fidelity together in one pedal. Whether you're looking for a little bump in your gain to get that perfect blues tone or want to beef up a delay or flanger for big '80s sounds, the LGW may be small in stature, but it's enormous in its sonic mark.
