Description

Three flavors of authentic tube tremolo, at your feet. Evolved from the flagship Astra Modulation Machine, Flow Vintage Tremolo gives you three flavors of tube-driven wiggle and shake — from old school to modern — in a dapper, compact package.

Immerse yourself in the chewy throb of early 60s American brown amps, and add a syrupy mix of volume fluctuation and phase shifting — far beyond the original circuit — that s perfect for vintage soul, surf, and even Uni-Vibe textures.

Play through an exhaustive end-to-end emulation of a classic 1965 American tube amp s optical tremolo circuit, and get the pulsating shimmer of the most famous vibrato ever created. Sounds just like your favorite old record!

Built from the ground up using UA s own virtual optical photocell, get the rippling beauty of square waveforms and dive into rhythmic trem effects that enhance any genre, from modern pop and R&B to blues and indie rock.
