The Kepma F0-B and F0E-B Grand Auditorium guitars are the most affordable in the Solid Top Series. They are priced so anyone can afford a super high-quality guitar with exceptional tonal characteristics, plus with the addition of the AcoustiFexy K-10 Pro Pickup, Preamp &FX system, you'll experience a level of sound and inspiration that's completely alone in its class. Unbelievable value! However, other than price/value, there are quite a few innovations that separate these guitars from their competitors. Kepma is a technology focused company with the goal of combining science and art to produce some of the best instruments in the world. Judge for yourself: The top: F0-B and F0E-B Grand Auditorium guitars feature a torrefied solid top. The proprietary Kepma Torrefication Process uses a combination of controlled heat and humidity over a period of time to draw the moisture, oils and sap from the cellular structures in the wood to the surface, which is then sanded off. This process adds additional strength and stability to the tops while making them less reactive to atmospheric condition changes. Every solid Kepma top goes through this highly controlled process and it yields tops that react better to string vibration, are livelier and definitely more stable. New 4-Point Bolt-on Neck Joint: Kepma's new bolt-on neck joint is an industry first at this level. It provides stability like no other joint, plus it allows for precise and infinite adjustment should it be needed. Plus, with this design there's no pooling of guitar finish at the point of contact making future adjustment and maintenance a breeze! Ultra-thin Water-Based Finish: the precise application of the finish on a guitar is critical for both protection AND tonal properties and projection. Kepma's ultra-thin (0.042mm) water-based finish is not only environmentally friendly and durable, but also boasts exceptional gloss and hardness. When applied in an ultra-even thin layer, it virtually does not interfere with the guitar's vibration transmission, ensuring a purer, more natural sound that perfectly showcases the wood's natural tonal beauty. AcoustiFexy K10 Pro System: the Newly Upgraded AcoustiFexy K10 Pro System features an enhanced vibration pickup system, built-in Reverb, Delay &Chorus, plus bluetooth audio streaming and a companion app. You can connect your guitar to any Bluetooth source and play music or backing tracks through the guitar, both unplugged and when plugged into an amp or mixing console. Plus, the OTG interface lets you hook up to the app to enable the looping function and rhythm section for composing on the fly and improv &practice. Additionally, built-in features such as a metronome, tuner, and drum machine make practice more engaging and efficient, elevating your overall guitar learning experience. C" Shaped Fast Neck: this FAST neck design offers a smooth, natural feel that reduces hand fatigue and enhances playing fluidity, allowing players to effortlessly master various playing styles. Even during fast playing, it maintains a comfortable grip and with the satin finish coating on the back of the neck, fast playing is a a breeze!
