Seicorde

The Seicorde is a crossover nylon-string guitar, reimagined with innovative features to enhance playability and tonal richness.

Sharing the elegant design principles of the Orchestra model, the Seicorde boasts an Overhang Neck with a 30″ radiused fretboard and the body joining at the 13th fret, and a carefully sculpted 52mm nut. Additionally, the External Tuning Slot system, a unique innovation, keeps the main resonances always between the notes, minimizing wolf notes for a harmonious sound, great sustain, and coherence across the neck.

The bracing system adopts an original T-Fan scheme, that makes for a very low equivalent mass of the soundboard (around 40 grams), and an exceptional mobility value of 22 (s/Kg³), offering a responsive and expressive sound.

Whether you’re a classical guitarist seeking a modern instrument with enhanced playability or a discerning player looking to expand your sonic palette, the Seicorde offers a captivating blend of tradition and innovation. Its rich, resonant voice and effortless response make it an ideal companion for both intimate performances and expressive explorations of the nylon-string guitar’s vast repertoire.

A little bossa-nova gem played by Alex is an original improvisation, on the Seicorde nylon string crossover prototype that Alex is playing in the latest months.

Overhang neck

The neck, crafted from a single, perfectly quarter-sawn billet of wood, is inserted directly into the gently radiused upper bout of the soundboard.

This eliminates the need for a traditional heel block, significantly enhancing the guitar body’s structural strength and elevating the soundboard.

This innovative design results in unparalleled playability, effortless access to the highest frets, and simplified maintenance.

Drop Port

The asymmetric upper port is maximizing the radiating surface of the soundboard’s monopole, to increase dynamic, responsiveness and expressivity.

The Drop Port also enhance the power at the low end without the typical muddy signature of the standard sound holes, and simplifies positioning of microphones in studio environnment.

External Tuning Slot

An innovation unique on the market, the ETS system tunes the main resonances perfectly between the notes, minimizing wolf notes.

The result is a coherent, harmonic and juicy sound, plenty of sustain and balance across the whole fretboard.

Each Seicorde includes an individual specification sheet with a frequency response report. This data helps you track the instrument’s evolution and aging, and the ETS system allows for fine-tuning the main resonances to maintain peak acoustic performance.

T-Fan Bracing

The original bracing scheme of the Seicorde model optimizes the strength-to-weight ratio, for a very low equivalent mass of the soundboard (around 40 grams), and an exceptional mobility value of 22 (s/Kg). The guitar is highly responsive, rich and expressive, while ensuring long-term reliability.

The fan-shaped bracing pattern also enhances the amplitude of dipoles and tripoles, resulting in an exceptionally rich spectrum of overtones.

Each instrument is meticulously tuned using a proprietary process, to avoid wolf tones on all main resonance modes. To offer a consistent sound all over the fretboard and an exceptional sustain at all frequencies.
