The Korena take
UAFX Flow Vintage Tremolo is a compact orange guitar pedal with three tube-driven tremolo voices, tap tempo, an emulated preamp circuit, and a volume control for make-up gain. Dharma blends volume fluctuation with phase shifting; 65 recreates an optical tremolo circuit; Square delivers square-wave tremolo textures. Selectable true or trails bypass lets you choose the bypass behavior. It connects through single 1/4-inch TS input and output jacks and needs an isolated 9VDC supply.
Strong match
Who this is for
- Setting tremolo rate with tap tempo while retaining a dedicated make-up gain control.
- Choosing between harmonic, optical, and square-wave tremolo textures in one compact pedal.
