The Swirl Pool is reminiscent of the unique modulation of tremolo and vibrato found on amps of the 1960s.  Swirl Pool creates a myriad of modulations based on that tone.

The two foot switches switch the effect ON / OFF and mode, respectively.  The two modes have the same Level and Tremolo controls, but you can set the Speed ​​and Vibe controls respectively and switch instantly with the foot switch.  This makes it possible to set each effect, and mode 1 can be used as a tremolo and mode 2 can be used as a vibrato.

The tremolo control creates a tremolo that gently shakes and turns on the Tremolo switch to
create a violently cramping tremolo. If you combine this with the Vibe control, you can create a radical tone that repeats a violent pitch shift
from a pleasant vibrato like singing. Features – True bypass specification – Pre / post switchable effect loop (Universal Loop) – Effect loop active only in mode 2 (Speed ​​2 Loop)
