This is a 28-fret model from the Aria Pro II MAC series. It was an original model released by Mitaka Gakki in the late 90s. Sound output has been confirmed, and there is no severe noise. However, as it's been nearly 30 years, those who are concerned may need to replace the electrical components. The neck condition is straight, and fret wear is minimal, mostly in the low positions. The pickups are quite high-powered, and the rear pickup has a coil-tap function. There is paint chipping on the control panel side. The tremolo arm is not included. With 28 frets, you can cover the same range as a standard 24-fret guitar even when tuned down two steps. This is recommended for those who want to tune down but don't like 7-string guitars. Please understand that this guitar is over 25 years old and has been played quite a bit.
