Product Detail
The Universal Audio Compact Flow Vintage Tremolo Guitar Pedal, inspired by the well - known Astra Modulation Machine, brings you three unique tube - driven tremolo effects. This small but mighty pedal lets guitarists dive into retro sounds, from the deep, throbbing tones of 1960s American amps to modern tremolo textures suitable for soul, surf, blues, and indie rock. By accurately mimicking the optical tremolo circuit of a classic 1965 American tube amp, it produces that amazing pulsating shimmer heard on iconic records. A proprietary virtual optical photocell allows you to explore square waveforms and rhythmic tremolo effects for various musical styles. The Flow Vintage Tremolo is built to last. Its perfectly captured tube preamp makes your tones more three - dimensional and harmonically rich. The combination of tube preamp warmth and well - tuned tremolo modes offers a wide range of sounds. Features like switchable true/trails bypass, tap tempo, and “make up gain” Volume control ensure your tremolo stands out in any mix. It's a must - have for guitarists.

Using this pedal is easy. First, connect it to your guitar and amplifier using the 1/4” TS unbalanced input and output. Make sure to use an isolated 9VDC power supply (center - negative, 250mA minimum), which you need to buy separately. Once it's powered on, you can select different tremolo modes like Dharma, 65, or Square to get the sound you want. Use the tap tempo feature to synchronize the tremolo effect precisely. Adjust the volume control to make your tremolo stand out in the mix. If you want to bypass the effect, you can switch between true and buffered bypass. When it comes to firmware updates, connect the pedal to your computer via the USB Type - C port. For maintenance, keep the pedal clean and dry. Avoid exposing it to extreme temperatures or humidity. If there are any issues, refer to the warranty registration card or the quick start guide.
