The Electro Harmonix Deluxe Big Muff Pedal takes the iconic Big Muff pedal and expands on its capabilities for even more versatility. It features the familiar sustain, tone and volume controls from the original device to shape your overall distortion tone and it adds in new mid-controls alongside a gate to remove unwanted hum.
The expression pedal input also gives you the ability, with the use of an external expression controller, to remotely sweep your mid-frequencies and gain new wah-like effects. The attack control adds definition to chords and riffs while the gate can be used in new ways to provide blasts of fuzz when you play and silence when you don't.
This takes the original Big Muff Pedal and gives it a whole new lease of life, delivering greatly expanded sonic capabilities to experiment with and find your new signature tone.
