The RV-3 is a combination digital reverb and delay pedal well-regarded for its studio-quality sound, featuring four distinct reverb modes and three delay modes. Musicians can achieve delay times of up to 2,000ms, providing versatility for various soundscapes. It allows for a simultaneous operation of both delay and reverb effects with settings for Room 1/2, Hall, and Plate types. Control is intuitive via dedicated knobs for Balance, Tone, Reverb Time, and Mode, making it user-friendly for live setups. Although now discontinued, it remains a favorite for professionals who appreciate its quality and reliability.
