Duke GA-PF Jumbogitar

Grand Auditorium Acoustic Guitar with Solid Spruce Top and Rosewood Body

The Duke GA-PF is an elegant Grand Auditorium acoustic guitar designed for advanced players who want one instrument for strumming, fingerstyle and accompaniment. A solid Swiss alpine spruce top paired with a laminated East Indian rosewood body delivers balanced, loud sound with deep bass and brilliant overtones. The traditional body without a cutaway keeps the focus on a full, even acoustic voice.

What Sets the GA-PF Apart

Like every Duke, the GA-PF is finalized by guitar builders in Tübingen, Germany. It leaves the workshop with newly dressed and polished frets and a play-ready string action, so it plays comfortably from the first chord. Selected materials such as a bone saddle and an ebony fingerboard are part of the standard equipment, together with an Elixir Nanoweb string set.

Tonewoods and Body — Spruce Clarity, Rosewood Depth

The spruce top gives the guitar clarity and headroom, while the East Indian rosewood back and sides add deep bass and rich overtones.

• Top: Solid Swiss alpine spruce — clear, dynamic response with strong projection
• Back & Sides: East Indian rosewood — deep bass and brilliant overtones
• Body: Grand Auditorium, no cutaway — balanced voice for many playing styles
• Binding: East Indian rosewood — elegant frame for the body

Neck and Playability — Stable and Easy to Adjust

The neck combines a Spanish cedar shaft with a dual-action truss rod and an ebony fingerboard for a stable, smooth playing surface.

• Neck: Spanish cedar (cedro) with dual-action truss rod — light, stable and precisely adjustable
• Fingerboard: Ebony — dense, smooth surface for clear note definition
• Scale Length: 650 mm — full scale and familiar string tension
• Nut Width: 45 mm — comfortable spacing for chords and fingerstyle

Hardware and Finish — Bone, Ebony and High Gloss

The hardware is chosen for efficient string-to-body transfer and reliable tuning.

• Nut & Saddle: Bone — efficient transfer of string vibration
• Bridge: Ebony — dense anchor for the strings
• Machineheads: Closed, chrome — smooth tuning action and stable tuning
• Finish: High gloss — protects the tonewoods and shows off the grain
• Strings: Elixir Nanoweb 80/20 Bronze .012–.053 — coated for long tone life

Who the GA-PF Is Built For

The GA-PF is the right choice for advanced players who want a balanced, loud acoustic guitar with the clarity of spruce and the depth of rosewood. Singer-songwriters will appreciate how the Grand Auditorium body supports a voice, while fingerstyle players benefit from its even response across the strings. Right-handed players get a guitar that is set up and ready to play straight out of the box.
