Guitar effects pedal with three types of tube-driven tremolo effects, tap tempo, perfectly emulated preamp circuit,
volume boost and true/buffered bypass, all in a compact pedal.

Three flavors of authentic tube tremolo, at your feet.
Evolved from our iconic Astra modulation machine, Flow Vintage Tremolo offers three flavors of tube-driven movement and agitation,
from old-school to modern, in a sleek and compact package.

Dharma: Experience a thick harmonic tremolo
Immerse yourself in the smooth pulse of early 1960s American "brown" amplifiers and add a syrupy blend of volume fluctuation and phase shift, going far beyond the original circuit,
which is perfect for vintage soul, surf, and even Uni-Vibe textures.*

65: Enjoy the perfect tube amp tremolo
Play through a comprehensive end-to-end emulation of the optical tremolo circuit of a classic 1965 American tube amplifier and get the pulsating brightness of the most famous "vibrato" ever created. Sounds just like your favorite old record.

Square: add modern and choppy textures
Built from scratch using our own virtual optical photocell, get the undulating beauty of square waveforms and immerse yourself in rhythmic vibration effects that enhance any genre, from modern pop and R&B to blues and indie rock.
