Electro-Harmonix Deluxe Bass Big Muff Pi review

The Bass Big Muff Pi from Electro-Harmonix has been loved by players for years, but this latest Deluxe incarnation takes bass distortion to a whole new level.

The sustain and tone controls are retained from the original Big Muff, but here we have a bigger and more complex unit with many enhancements.

Sounds

The blend control mixes the distorted sound with the dry signal, while the Crossover section has its own dedicated footswitch, and features a low- pass filter added to the dry signal, plus a hi-pass filter positioned in the circuit ahead of the distorted sound.

This is particularly impressive, because it not only smooths the distorted sound, but it adds something like funky parametric tone-shaping, and is worthy of being a pedal in its own right.

The low pass is also great, since it tightens your tone and fattens the selected area of operation. The Gate function is used to eliminate any hum that might be generated by mains, lighting or simply by close proximity to high-gain amps.

With a Pad switch on the input signal for passive and active basses, plus an expanded output section with clean direct out and two effected outputs (balanced DI and standard jack socket), this pedal has got it all.
