The SwirlPool is a two-speed synchronized Tremolo/Vibe similar to circuits common in vintage 60’s amplifiers.

The new SwirlPool Tremolo/Vibe pedal is Amptweaker’s first dive into non-distortion pedals, and was the most commonly requested pedal by consumers on Amptweaker’s website. Reminiscent of the synchronized Tremolo and Vibrato circuits common in some vintage 60’s amplifiers, this analog pedal can duplicate many different types of modulation tones….as well as invent a few new ones.

The two footswitch buttons provide bypass and speed control, allowing the user to switch between two different Speed and Vibe settings while sharing a common Tremolo control. If a Vibe knob is turned down, then the sound will be only tremolo, and can be tweaked from smooth to ‘Jerky’….but as the Vibe is added, the resulting combination can provide a subtle vocal quality or a dramatic pitch shift.
