The Irvin Guitars SJ (Small Jumbo) - Lutz Spruce & Indian Rosewood is a visually captivating and sonically inspiring instrument, handcrafted by one of the most passionate and meticulous luthiers in the modern boutique scene—Wayne Irvin Johnson. More than just a skilled guitar maker, Wayne is a devoted performing artist and songwriter whose deep understanding of what a musician seeks in an instrument is woven into every aspect of his builds. His dedication to expressive tone, dynamic range, and lasting inspiration stems not only from years at the bench, but also from countless hours on stage and in the writing room. This dual perspective gives Irvin guitars a rare musical soul—built for the player, by a player.

The SJ model is Wayne’s take on a refined small jumbo, offering an ideal balance of clarity, headroom, and warmth. The Sonic Graded Lutz Spruce top, sourced from the revered Pacific Rim Tonewoods, delivers the strength and tonal complexity of Sitka with a touch of the sweetness found in Engelmann. It’s the perfect match for the Indian Rosewood back and sides, which provide rich low-end, glassy trebles, and the wide dynamic range essential for both fingerstyle nuance and strumming authority.

Visually, the guitar is nothing short of elegant. The Florentine cutaway adds a dramatic aesthetic flourish while offering improved upper fret access. The 5-piece laminated neck, composed of mahogany, curly maple, and padauk, is both beautiful and stable, while its tactile feel invites hours of effortless play. Ebony bindings trace the guitar’s silhouette with subtle refinement, complemented by top purfling in black/maple/black – rosewood – black/maple/black, a sophisticated touch that rewards close inspection.

The appointments continue with a rosewood and paua rosette, and ebony bridge pins that sparkle with brass rings and paua dots—small yet meaningful details that reflect Wayne’s obsessive eye for both beauty and balance. The upper bout sound port adds dimension and immediacy to the player’s experience, creating a surround-sound sensation that makes the guitar feel alive in your hands.

Hardware is top-tier and dialed in for stability and performance, including a bone nut and saddle, and Gotoh 510 tuning machines in black chrome for smooth, accurate tuning. The ebony bridge and fingerboard, along with the ebony headstock veneer and Indian rosewood backstrap, complete the aesthetic with a sense of visual unity and elevated craftsmanship.

With a 25.5” scale length, 1 3/4” nut width, and 2 1/4” bridge spacing, the SJ plays with perfect comfort and response. The body’s elegant dimensions—11” upper bout, 15 1/2” lower bout, 9 1/2” waist, and 19 1/2” body length—coupled with a depth range from 3 1/2” to 4 1/2”, give this guitar a natural acoustic projection and resonance that belies its manageable size. Weighing in at just 4 lb 7 oz, it’s featherlight in hand, yet thunderous in tone.

The Irvin SJ is not just a guitar—it’s a statement piece from a builder whose artistic vision is steeped in authenticity, devotion to music, and unwavering attention to detail. It is a masterfully built companion for serious players, collectors, and those seeking a deeply expressive voice with unmistakable style.
