For over 50 years, the classic three - knob Big Muff Pi has been celebrated for its sweet singing tone and violin - like sustain, shaping the rock guitar sound. Now, the EHX Deluxe Big Muff Pi takes it further. It offers all the classic tones of the original NYC Big Muff Pi and more. The foot - switchable Mids section allows you to boost or cut an adjustable mids frequency, giving you added definition or massive scooped tones. You can even add an optional expression pedal to transform it into an extreme fuzzed - out wah! The Attack control keeps your pick attack sharp with an enhanced dry signal, and the Bass Boost adds a deep rumble at higher tone settings. The Gate gets rid of unwanted hiss for a more dynamic performance. This is the most versatile Big Muff yet! Features include delivering classic sounds with extra options, a foot - switchable MIDS section for better recording and live play, four - control MIDS section for midrange fine - tuning, a noise gate to eliminate noise while keeping your tone, adjustable Attack for punchy notes and chords, switchable Bass Boost, an Expression Pedal input for real - time mid sweeping, true bypass for signal integrity, and a 9V battery included. Specifications: Analog circuit, true bypass, mono audio, 9V battery (optional 9.6VDC - 200mA power adapter not included), dimensions of 5.75' x 4.75' x 2.5', 22mA current draw, and released in 2014.



Using the Electro - Harmonix Deluxe Big Muff Pi is a breeze. First, connect your guitar to the input of the pedal and your amplifier to the output. You can power it with the included 9V battery or an optional 9.6VDC - 200mA power adapter. When using the pedal, adjust the knobs to get your desired sound. The Attack control can make your single notes and chords more punchy. The Bass Boost adds more bottom end when you need it. The foot - switchable MIDS section is great for getting the right midrange in your recordings or live performances. If you have an expression pedal, connect it to the input to sweep the mids in real - time. As for the noise gate, adjust the Gate control to reduce unwanted noise and hum without losing your original tone. When it comes to maintenance, keep the pedal in a dry place. If you're using a battery, replace it regularly to ensure consistent performance. And when not in use, turn it off to save power. Also, be careful when handling the pedal to avoid any physical damage.
