The BM-90C, crafted by K.Yairi's master luthier, Akinobu Michimae, is a special instrument brimming with the craftsman's dedication and passion. For this model, Mr. Michimae personally selects the wood and oversees every step of the manufacturing process. Reflecting his experience, skill, and keen sensitivity to sound, this guitar boasts a level of perfection truly worthy of being called a "work of art."
The tonewoods used for the top, back, and sides are all meticulously selected. Only wood meeting Michimae's exacting standards in dryness, density, and the beauty of its grain is used. The result is a guitar with exceptional resonance, delivering a remarkably rich body tone and profound depth of sound. These are truly "chosen" materials, combining visual beauty with acoustic superiority.
The BM-90C's signature is a delicate yet focused sound. It responds readily to even the lightest touch, faithfully expressing complex chords and subtle nuances without compromise.The mid-to-low frequencies possess warmth and substance, ensuring the guitar maintains a distinct presence even during chord strumming. Conversely, the high frequencies are clear and project well, delivering a beautiful, well-defined sound image for fingerstyle and arpeggios. This tonal quality, which draws out the player's expressiveness, is precisely what defines a guitar crafted by master artisans.
Above all, the appeal of the K.Yairi Custom Shop lies in its meticulous craftsmanship. Every detail—from the neck angle and fret edge finishing to the lacquer thickness and balance—is carefully considered to enhance playability. It remains comfortable even during extended performances, with no compromise on attack or sustain. The high quality of the handcrafted work poured into each instrument will deepen your trust and affection the more you play it.
This BM-90C is a guitar that can become a "trustworthy partner" for every guitarist who takes their music seriously. We invite you to experience the sound and form born from the hands of master luthier Akinobu Michimae.
