Yellow Squash Sound Labs Iron Fist compressor

The IronFist is a 4-knob compressor/sustainer pedal with a built-in noise gate.

    The pedal works by making loud notes quieter (the compression circuit), and quiet notes louder (added sustain) with minimal altering of your original tone.

   
    There is no added distortion that is audible.

The most notable feature is the noise gate circuit which eliminates and audible noise that is quieter than the set threshold. 

If you are looking for sustain and something to smooth out your tone and add punch at the same time, look no further. The IronFist would make a great choice.
