Flow models three tube amp tremolo circuits, from the soft pulse of an opto tremolo to the swirling harmonic tremolo, along with the tube preamp stage the effect ran through. Tap tempo keeps the pulse with the band, and the Volume control can act as a boost.
It brings back the tremolo players miss from vintage amps, or adds one to an amp that never had it. For tremolo alongside chorus and flanging, the Astra covers it in stereo.
