Engelmann spruce / Indian rosewood
Eclipse Anniversary Koa Gc-ER a
The Eclipse Anniversary Koa Gc-ER a is a special 45th anniversary interpretation of the popular Eclipse Series, combining its sleek all-black aesthetics with exclusive commemorative design elements. Featuring a Full-Pore High-Gloss Finish in Piano Black, the guitar is elevated by premium solid koa appointments on the Bevel Duo, body binding, rosette, fretboard inlay, and headstock detailing. The warm character of koa creates a striking contrast against the deep black body, giving the instrument a bold yet refined visual identity.
Produced in a strictly limited run of only 45 instruments, the Eclipse Anniversary Koa Gc-ER a also features a custom anniversary headstock inlay created specifically for this milestone edition. The inlay is composed of 45 miniature letter “F” shapes, with a single solid koa “F” identifying the individual production number of each guitar within the limited run. This makes every instrument not only visually distinctive, but also uniquely tied to the 45th anniversary of Furch Guitars.
At its core is an individually voiced Engelmann spruce soundboard, optimized for balanced tone, dynamic response, and harmonic richness, combined with Indian rosewood back and sides. The resonance-enhancing Full-Pore High-Gloss Finish protects the instrument while allowing the soundboard to make the most of its natural acoustic properties and projection. Long-term stability and consistent playability are ensured by the CNR System® Active neck joint, which automatically adapts to changes in ambient humidity and allows effortless string action adjustments. For stage and studio use, the Eclipse Anniversary koa comes equipped with the LR Baggs HiFi Duet pickup system as standard. The guitar also features the Bevel Duo ergonomic design, with bevels at both the forearm and rib positions. Made of solid koa, this feature increases long-term playing comfort while serving as one of the model’s most striking visual highlights.
Created to celebrate the 45th anniversary of Furch Guitars, the Eclipse Anniversary Koa Gc-ER a features an exclusive commemorative headstock inlay designed specifically for this milestone edition. The inlay is composed of 44 white pearl letters “F”, each symbolizing one year of Furch history. A single solid koa “F” identifies the individual production number of each guitar within the strictly limited run of 45 instruments, making every piece uniquely tied to this anniversary.
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 UV-polymerized lacquer, which not only protects the instrument but also enhances its natural resonance, resulting in a richer, fuller sound that brings out the true character of each note. On the Eclipse Anniversary Koa Gc-ER a, the Full-Pore High-Gloss Finish in elegant Piano Black gives the guitar a sleek, luxurious appearance while preserving its acoustic responsiveness. The deep black surface also creates a striking backdrop for the solid koa appointments, allowing their warm character to stand out beautifully.
Our unique voicing process fine-tunes each soundboard to perfection, resulting in guitars that consistently 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 fretboard of the Eclipse Anniversary Koa Gc-ER a balances stage-ready functionality with refined visual detail. Linear side position markers crafted from white mother-of-pearl ensure clear orientation in any lighting conditions, offering confident navigation across the neck. On the front of the fretboard, koa inlays echo the guitar’s exclusive anniversary appointments, creating a warm contrast against the sleek all-black aesthetic of the guitar.
Maximum protection for your instrument during transport and storage is ensured by the highly durable Furch T-Line Case. Its timeless design combines elegant lines with high-quality, reliable hardware. The thermoformed shell, reinforced with rigid polyurethane foam, offers the perfect balance of strength and light weight, while the luxurious long-feather cloth interior is precisely molded to the guitar, protecting it against impacts and changing environmental conditions.
