Ibanez AAM50-OPN Advanced Auditorium - Open Pore

Acoustic western guitar, Advanced Auditorium

The Ibanez AAM50-OPN is a western guitar in the Advanced Auditorium series with an open pore finish. It is designed for high playability and balanced tone in both studio and stage settings, suitable for solo and ensemble performance. The construction emphasizes detailed craftsmanship, focusing on tone and design.

Tone and construction

The body has a solid Sitka spruce top with sapele back and sides, providing a warm and clear tone with long sustain. The specially designed X-M bracing enhances tone projection and balance across bass and treble.

Sound port

The AAM50 features an A.I.R. Port (Acoustic-Information-Response) positioned toward the player for improved monitoring. Angled wooden blocks direct the sound out of the port, providing clearer feedback without affecting the acoustic tone.

Neck and playability

The neck is made of okoume with a low oval grip and a purpleheart fingerboard and bridge. It is designed for comfort and control, with a 43 mm nut width and a 634 mm scale. Jumbo frets allow flexibility for fingerstyle and pick playing.

Body and design

The Advanced Auditorium body offers a balanced playing position. Rounded body edge binding, chrome die-cast tuners with 18:1 gear ratio, and Ibanez Advantage bridge pins complete the instrument. Strings are D’Addario Coated Phosphor Bronze (012-053). Included gigbag: IAB540-BK.
