Guitar World Verdict

This is one very busy bee. It’s capable of a range of powerful conventional tones, but its main function could be as your pedalboard’s wildcard with its staggering array of off-the-wall effects, perhaps making an instant impact using the Momentary switch to bring things in and out. We might need a sit-down.


  • +

    Solid build quality.

  • +

    A wide and quirky range of sounds.

  • +

    Onboard presets.


  • -

    Steep learning curve.

  • -

    Low octave can get unwieldy.

The latest from Beetronix, the Zzombee, is described as a ‘Filtremulator’. This is a one-of-a-kind analogue multi-effect pedal featuring Filter, Wah, LFO, Randomized Filter, Tremolo, Swells, Overdrive, Fuzz and Low-Octave, plus a unique effect called Cross Tremolo where the tremolo pulse alternates between root note and low octave.

The pedal has a set of controls that combines the effects for some very unusual sounds, but it may take some time to get your head around the four three-way toggle switches, three knobs and two multi-function footswitches.
