The RV-3 is a combination digital reverb and delay pedal designed for musicians seeking high-quality sound in a compact format. It features four high-density reverb modes, which include Room, Hall, and Plate effects, alongside three delay modes that offer delay times up to an impressive 2,000ms. Musicians can easily create a rich soundscape by combining reverb and delay effects simultaneously. An intuitive control interface allows users to adjust parameters with Balance, Tone, Reverb Time, and Mode knobs. Although the RV-3 is now discontinued, it remains known for its studio-quality sound and versatile applications in live settings.
