Universal Audio UAFX Flow | Recreating Classic Tube Amp Vintage Tremolo Pedal

Three Legendary Amp Tremolos, All in One Compact Pedal

The Universal Audio UAFX Flow is a vintage tremolo effect pedal from Universal Audio, featuring advanced digital algorithms derived from the Astra Modulation Machine, offering three classic tube tremolo effects. This compact stompbox utilizes an intuitive three-knob design, allowing guitarists to easily dial in various tremolo textures, from gentle pulses to dramatic chops, while also featuring Tap Tempo for precise synchronization with song tempo.

Compared to other digital tremolo pedals on the market, the unique aspect of UAFX Flow lies in its precise simulation of the warm tone and harmonic richness of tube preamps. It not only recreates classic amp tremolo circuits but also captures the fullness and dynamics of pushed preamp tubes, delivering a more authentic amp tremolo effect.

Universal Audio UAFX Flow Core Technologies and Features

Three Classic Tube Tremolos: Offers three meticulously modeled tremolo algorithms, recreating the most iconic tube amp tremolo effects in history, covering a tonal range from subtle to aggressive.
Dharma Harmonic Tremolo: Inspired by brown-panel amps from the late 50s to early 60s, its unique combination of volume fluctuations and phase shifts creates a chewy, soulful rhythmic feel, perfect for classic R&B and Swamp Rock tones.
'65 Optical Tremolo: Directly from the acclaimed UAFX Astra pedal, this mode recreates the iconic optical tremolo of classic black-panel amps from the mid-60s, delivering a crisp, choppy effect that is widely recognized as the industry-standard tremolo tone.
Square Wave Tremolo: Built from the ground up by the Universal Audio team, utilizing virtual optical photocell technology, it delivers a sharp-edged, rhythmically intense square wave tremolo, suitable for modern music styles that demand strong rhythmic dynamics.
Built-in Tube Preamp Emulation: More than just effect simulation, UAFX Flow also features built-in tube preamp emulation circuitry, adding warmth, rich harmonics, and natural compression to the overall tone.
Intuitive Three-Knob Control: Adopting a classic stompbox design, the Depth, Speed, and Volume knobs allow for quick and intuitive adjustment of tremolo depth, speed, and output level.
Tap Tempo Function: Supports footswitch-controlled Tap Tempo, allowing musicians to instantly and precisely synchronize tremolo speed with the band or backing tracks.
Switchable Bypass Modes: Offers True Bypass and Buffered Bypass options, allowing users to choose the mode that best maintains signal integrity based on their pedalboard setup and cable length.

Dharma Mode: Brown-Panel Harmonic Tremolo

Recreates the unique tremolo effect of classic brown-panel amps from the late 1950s.
Combines volume fluctuations with phase shifts to produce a "chewier," more musical rhythmic feel than traditional tremolo.
Ideal for vintage R&B, soul music, and blues that requires subtle dynamics.

'65 Mode: Black-Panel Optical Tremolo

Derived from the classic algorithm of the UAFX Astra pedal, simulating the optical tremolo of mid-1960s black-panel amps.
The tone is crisp and choppy, considered by many guitarists to be the standard tremolo sound.
Versatile, suitable for almost all genres requiring clear tremolo, from surf rock to country music.

Square Mode: Modern Square Wave Tremolo

A tremolo mode exclusively developed by Universal Audio using virtual optical technology.
Delivers a hard, sharp-edged square wave tone, creating a highly impactful and rhythmic sound.
Suitable for modern pop music, electronic music, or any musical creation requiring strong, mechanical rhythmic dynamics.
