Universal Audio Flow Vintage Tremolo Pedal with Stompbox Design and Dharma, 65, and Square Modes

Evolved from the flagship Astra Modulation Machine, the Universal Audio Flow Vintage Tremolo Pedal gives you three flavors of tube-driven wiggle and shake from old school to modern in a dapper, compact package.
Dharma - Experience Thick Harmonic Tremolo
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.
65 - Indulge in Perfect Tube Amp Tremolo
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.
Square - Add Modern, Choppy Textures
Built from the ground up using the 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.
Get the Authentic Tone of a Tube Preamp
Flow gives you the warm, complex sounds of a tube preamp - in this case from early and mid-'60s American combos - so your tremolo effects are more present, three-dimensional, and musical.
Paint The Town with a Rugged, Compact Stompbox
Built for years of trustworthy performance, Flow Vintage Tremolo gives you switchable true/trails bypass, tap tempo, and ‘makeup gain’ Volume control to ensure your tremolo effects are heard loud and proud for years to come.
