The Irvin Guitars SB Signature Baby – Lutz Spruce & Koa is a dazzling showcase of sonic elegance and intimate craftsmanship from boutique luthier Wayne Irvin Johnson, whose instruments continue to gain admiration for their blend of fine artistry, musical sensitivity, and unmistakable character. Wayne’s dual life as both a master builder and a performing songwriter informs every detail of his guitars—each one not just a refined tool, but an expressive companion that invites deep musical exploration.

At the heart of the SB Signature Baby lies a sonic-graded Lutz spruce top, carefully sourced from the renowned Pacific Rim Tonewoods. This select tonewood brings together the dynamic power of Sitka and the sweetness of Engelmann, delivering a voice that is responsive, clear, and richly nuanced—perfect for fingerstyle players and light strummers seeking expressive touch sensitivity. Paired with figured koa back and sides, the tone is warm, glowing, and articulate, with a golden shimmer in the midrange and crystalline clarity across the treble spectrum.

Though compact in size, the SB Baby is brimming with thoughtful design and exquisite appointments. The 12-fret body, featuring a 9 15/16" upper bout, 14" lower bout, and a 24.9” scale length, makes for a supremely comfortable playing experience. The guitar’s depth—3" at the heel and 4" at the tail—contributes to a surprisingly full low-end response given its diminutive proportions. Weighing in at just 3 lb 13 oz, it is lightweight yet resonant, with an upper bout sound port offering a stereophonic dimension that brings the guitar’s voice closer to the player’s ear in a wonderfully immersive way.

Wayne’s eye for aesthetic harmony shines throughout. Ebony bindings provide a sleek visual frame, while the top is adorned with striking black/maple – koa – maple/black purfling, adding both contrast and elegance. The koa and paua rosette, koa backstrap, and koa-button Gotoh 510 mini tuners tie the visual palette together with natural richness and subtle iridescence. An ebony fingerboard and bridge, maple fingerboard purfling, and an ebony headstock veneer underscore the instrument’s refined material selection and attention to line and contour.

Functional touches meet luxurious detail: a bone nut and saddle, ebony bridge pins with brass rings and paua dots, and 1 3/4" nut width with 2 1/4" bridge spacing give the player modern comfort and control. The feel is buttery and responsive, and the voice is instantly inspiring—airy and articulate, with a refined sweetness that only a small-body guitar of this caliber can deliver.

The SB Signature Baby is a heartfelt expression of Wayne Irvin Johnson’s ethos as a luthier: to build guitars that speak with grace, beauty, and musical honesty. Housed in a Cross Rock case, it’s ready for the road, the writing room, or the stage. More than an instrument, it’s a personal statement—compact in form, infinite in expression.
