UAFX Flow Vintage Tremolo Guitar Pedal

Three flavors of authentic tube tremolo, at your feet.The UAFX Flow Vintage Tremolo was developed from the flagship Astra Modulation Machine to give you three flavors of tube-driven wobble and shake — from old school to modern — in a sleek, compact package. Enjoy the pulse of early '60s American "brown" amps, and add a syrupy mix of volume fluctuation and phase shifting — much more than 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 and sounds just like your favourite old record. Built from scratch using a 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.

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. Made for years of reliable performance, Flow Vintage Tremolo gives you switchable true/trails bypass, tap tempo, and "make up gain" Volume control to ensure your tremolo effects are heard loud and proud for years to come.
