Kenny Hill Signature 640 Spruce W/Barbera Soloist Transducer 2022 - French polish

The Kenny Hill Signature 640 Spruce is a contemporary concert classical built for players who require projection, tonal depth, and refined responsiveness. Designed with modern double-top technology and executed with traditional attention to detail, this model has become a trusted instrument among performing artists and educators.

This example pairs advanced construction with professional-level amplification and setup work performed here at Marfione Guitars.

Double-Top Construction

The soundboard is built around an ultra-light Nomex core bonded between two exceptionally thin tonewood layers:

• Outer layer: Alpine spruce (clarity, focus, projection)
• Inner layer: Red cedar (warmth, tonal complexity)
• Bracing: Lattice design for fast response and sustain

The result is a top that speaks immediately, maintains articulation at higher dynamic levels, and produces impressive headroom.

Materials & Structural Details

• Scale Length: 640mm
• Back & Sides: Indian rosewood
• Sides laminated with cypress lining
• Neck: Spanish cedar with precision V-joint
• Fingerboard: Elevated ebony
• Truss Rod: Two-way adjustable
• Tuners: Gotoh deluxe
• Finish: Hand-applied French polish

The elevated fingerboard enhances upper-register access while subtly influencing string geometry for efficient vibrational transfer.
