The Seymour Duncan Dirty Distortion Pedal gives you all the killer tones from your favourite classic and hard rock songs. This versatile pedal gives you everything from a fat lead tone powerful crunch an open rhythm crunch and big saturated solo sustain. The Seymour Duncan Dirty Deed is designed to capture the character and responsiveness of a classic overdriven tube amplifier with elements of distortion fuzz and overdrive combined into a single versatile pedal. The distortion is thick and beefy with a sweet spot in the mid-range EQ and a strong bass response while highly responsive Treble Bass Gain and Level controls allow you to dial in your ideal sound whether youre using the Dirty Deed as your sole source of grit or youre adding some extra dirt to an already-overdriven amp. For maximum flexibility the Dirty Deed incorporates an active EQ for 12dB of treble and bass boost/cut. A pair of MOSFET transistors evoke the tube-like harmonics and lush sustain that only comes from dangerously pushed amplifiers. The pedal runs on standard 9v to 18v DC power supplies. At 18v the Dirty Deed enhances overall saturation and compression.
