Independent shopping perspective
The Electro-Harmonix Deluxe Bass Big Muff Pi is a bass distortion pedal with controls for shaping how clean and processed signals work together. Its blend control mixes dry bass with distortion, while the footswitchable crossover separates filtering duties: a variable low-pass filter handles the dry signal and a variable high-pass filter handles the distorted signal. Switchable 0 dB and –10 dB input settings accommodate passive and active pickups. A built-in noise gate and separate Effect, Direct, and XLR D.I. outputs give you multiple routing choices.
