## Summary description

UNIVERSAL UA - UAFX Flow Vintage Tremolo is a guitar effects tremolo pedal designed to shape amplitude modulation for electric guitar and other instruments.

## Long description

The UNIVERSAL UA - UAFX Flow Vintage Tremolo is a guitar effects pedal engineered to produce classic vintage tremolo tones for electric guitar and other instruments. It shapes amplitude modulation with intuitive controls to achieve subtle shimmer or pronounced pulsation while preserving signal integrity through true-bypass switching. The pedal suits studio sessions, live performance and pedalboard configurations where reliable tremolo dynamics and straightforward operation are required.
Advantages
The Flow Vintage Tremolo delivers a wide range of tremolo textures from smooth, slow waves to tight, rhythmic pulses using dedicated depth and speed controls. True-bypass switching maintains the original signal when the effect is disengaged, ensuring clarity and low noise. Compact form and simple control layout make it easy to integrate into pedalboards and to adjust quickly during performance or recording.
Suitable for
 Electric guitarists seeking classic vintage tremolo tones
 Session musicians and producers needing reliable amplitude modulation
 Live performers who require onstage switching and low-noise operation
 Pedalboard rigs where compact, compatible effects are needed
Key specifications
 Effect type: amplitude modulation (tremolo)
 Controls: depth and speed (rate)
 Switching: true-bypass switching for uncolored bypass signal
 Form factor: compact stompbox design suitable for pedalboards
 Power: designed for standard pedal power supply (centre-negative, commonly 9V) — verify compatibility with your power source
How to use
Connect the instrument to the pedal input and run the output to an amplifier or the next device in your signal chain. Use the speed control to set the tremolo rate and the depth control to adjust the intensity of the amplitude modulation. Engage or disengage the effect with the footswitch; when disengaged, true-bypass switching preserves your dry signal. Start with moderate settings and refine speed and depth to match the song’s tempo and desired texture.
Usage recommendations
For recording, experiment with lower depth settings to add subtle movement without masking the original tone; for rhythmic parts, synch the speed to the tempo of the track or use an external tap tempo if available elsewhere in your rig. Ensure a stable, appropriate power supply and place the pedal where it is easily accessible on your board for quick adjustments during performance.
