Furch Spectra Plus ER Siena Amber

A bold splash of color for players who express their individuality through striking aesthetics and remarkable tone. Spectra Plus ER Siena Amber combines a visually captivating design with a distinct acoustic character, crafted for those who want to stand out not only through sound, but also through style.

Built to meet the growing demand for guitars that look as unique as they sound, every Spectra Plus model offers a choice of eight beautifully vibrant top colors, applied using our Full-Pore High Gloss Finish. This radiant gloss is complemented by the natural feel of the back and sides, enhanced with our Open-Pore Finish, which leaves the wood’s surface structure visible.

The Spectra Plus ER Siena Amber pairs an individually voiced solid Engelmann spruce top with solid Indian rosewood back and sides, delivering a versatile, articulate tone with excellent resonance and a balanced acoustic response — the perfect sonic match to its bold appearance.

Designed for players who express their individuality as much through striking aesthetics as through standout tone, the Spectra Plus series offers eight stunning top color options, finished in our Full-Pore High-Gloss Finish. Each vibrant top is beautifully complemented by Open-Pore back and sides, creating a dynamic visual and tactile contrast. A bold look, for a bold sound.

Furch’s unique voicing process fine-tunes each soundboard to perfection, resulting in guitars that deliver crystal-clear, harmonically rich tone. This precise adjustment ensures a balanced and dynamic sound across the entire tonal range, allowing your music to truly come alive.

The Furch CNR System® Active neck design takes our original CNR System® to the next level, offering unparalleled stability and precision for players who demand consistent performance. This innovative design adapts seamlessly to changes in humidity while maintaining perfect playability, ensuring your guitar feels and plays the way you want it to—every time you pick it up. Featuring a dual-action truss rod encased in a rigid carbon structure, the system is further enhanced by a solid-wood expansion element that automatically adjusts the neck angle to maintain consistent string action over time. It minimizes the need for costly, time-consuming neck resets and eliminates maintenance concerns, giving you the freedom to adjust your setup quickly and easily and allowing you to immerse yourself fully in the joy of playing—because that’s what truly matters.

Every Furch guitar features our uniquely developed ultra-thin lacquer that not only protects, but also enhances your instrument’s natural resonance, creating a richer, fuller sound that brings out the true character of each note.

The Spectra Plus ER Siena Amber comes with a Full-Pore High-Gloss Finish on the top soundboard and a Open-Pore Finish on the back and sides, a combination that enhances both tonal response and beauty of the instrument.

The ebony fretboard of the guitar is equipped with special shortened frets which deliberately do not extend to the edge of the fretboard. This prevents them from protruding due to fretboard shrinkage at lower humidity. The resulting area contains a flexible ebony-colored filler, which can perfectly absorb any changes.
