Another unique pedal from EQD - the Hummingbird. It's essentially a great square wave tremolo pedal with a touch of delay. It you can add just a touch of tremolo to all out experimental while using the Rate knob to modify the waveform. The touch of delay (sometimes bordering on reverb) is great for thickening out the tone of the whole pedal and adding a nice slice of ambience. The 3 modes cycle slow, medium and fast tremolo.
