EASTMAN continues to produce high quality models at reasonable prices. The skills he has cultivated over many years of making violins, cellos, and double basses are also used in guitar making. Furthermore, in recent years we have acquired the legendary acoustic brand "Beaujois Guitars," and while fully absorbing its essence, we are further improving our processing precision. This is the Gibson-like "E10SS" with round shoulders! The top is made of Adirondack spruce, and the back and sides are made of mahogany, just like the J45! This spec is amazing for the price. The sound is also fantastic, and you can really feel the benefits of Beaujois' sound-making techniques! The sound concentrated in the mid-range, combined with the torque of the Adirondack, makes this a very powerful guitar. Eastman has taken its level of excellence to the next level by partnering with Beaujois! It is of such excellent quality that you will realize "this is great" the moment you play the first note. Although it is a "high cost performance" guitar, it has the ability to make you feel that it is a "genuinely good guitar" regardless of the price.
