ROLAND DJ Effects Processor EF-303 GROOVE EFFECTS Purchased new and used for several years, then stored in its original box. It has built-in effects with punch, such as a ring modulator and filter. Among them, the VOICE effect produces a sound similar to a vocoder, making it a versatile effect that can be used on its own. The cutoff and resonance knobs allow for synthesizer-like sound changes, making it easy to use intuitively, even for non-DJs. Developed for DJs, it's equipped with effects that seem to fit dance music sounds, and the effects are intense, making it a fun piece of equipment for those who want to create a strong effect. Operation has been confirmed with no noise or crackling. Overall, it's in good condition, but there are scratches near the Roland logo and next to the tap button. The film cover is still attached to the BPM/VALUE display. Includes adapter. Will be shipped in its original box. I am also listing vintage effects processors from 20-30 years ago. #ef304 #roland #ローランド #エフェクター #シンセサイザー
