Roland Aerophone Go AE-05 Digital Wind Instrument I purchased this to practice saxophone fingerings at home. I bought it in 2019 and used it for about six months, but I became busy with work and have kept it stored at home. I only used it at home, so the case is clean. A digital wind instrument that you can play anytime, anywhere An electronic instrument that produces sound just by blowing into it You can play 11 different tones, including saxophone, flute, and clarinet. Thank you for your purchase if you understand that this is a used item.
