• Back & Sides: Highest-quality, premium solid Brazilian Rosewood with dramatic, dark, straight figuring.
• Top: Masterfully aged, tight-grained solid German Spruce that has matured over 50 years to produce a massive, expressive voice.
• Acoustic Lineage: Hand-built under the direction of master luthier Toshihiro Kato using the traditional Spanish construction blueprints, internal bracing profiles, and voicing techniques introduced by Ferrer. [1, 2, 3, 4]

Specs & Perfected PlayabilityUnlike typical vintage Grand Concerts that suffer from high action or neck bowing, this example plays flawlessly like a modern concert instrument.

• Action: Professionally optimized and set perfectly straight at a low, ultra-comfortable 3.0mm at the 12th fret on both the bass and treble E strings.
• Nut Width: 52mm [1]
• Scale Length: 660mm [1]
• Fretboard & Neck: Brand new, upgraded high-grade ebony fretboard expertly installed by Alfredo Velázquez to correct the straightness for premium, buzz-free concert playability. (Velázquez restoration is a minor structural upgrade that preserves the historic voice while giving it contemporary, elite action).

Concert VoiceThe sound is rich, bold, and overflowing with deep Spanish flavor. It projects crystalline, singing trebles and the dark, thunderous, complex bass signature that can only be extracted from premium, decades-aged solid Brazilian rosewood. Its response is immediate and perfectly balanced across all registers. [1]What’s Included
