Universal Audio Pedals - UAFX Flow Vintage Tremolo Pedal

Evolved from Universal Audio’s flagship Astra Modulation Machine, the Flow Vintage Tremolo packs three authentic tube‑driven tremolo voices, tap tempo, a perfectly emulated preamp circuit, volume boost, and switchable true/buffered bypass—old‑school vibe to modern chop, all in a compact stompbox.

Tremolo Voices

• Dharma – Thick harmonic trem based on early ’60s American “brown” amps, blending volume fluctuation and phase shift for vintage soul, surf, and Uni‑Vibe textures.
• 65 – Spot‑on optical tremolo emulation of a classic 1965 American combo, delivering the iconic shimmering pulse heard on countless records.
• Square – UA’s virtual optical photocell delivers modern square‑wave chop for rhythmic trem effects that suit pop, R&B, blues, and indie rock.

Authentic Tube Preamp Tone: Early‑ and mid‑’60s American combo circuitry adds warmth, depth, and dimension so every tremolo voice sits perfectly in the mix.

Road‑Ready Construction: Compact, rugged enclosure with tap tempo, trails/true bypass, and a “make‑up gain” Volume knob so your tremolo always cuts through.
