The CME Martin Guitar Tonewood Guide

Every Martin acoustic is a work of art, and not just because they smell like heaven when you open the case. The magic is in the wood — the grains, the density, the quirks of nature that shape the sound. Pick the right wood and your guitar will practically write the songs for you. Pick wrong… well, that’s why CME has a generous selection of “trade-ups.”

So let’s talk trees, tone, and why your next Martin might just sound more like you than you expect.

How Wood Shapes your Sound?

When you hit a string, the vibration travels through the bridge, into the body, and finally out into the air. Every square inch of wood it touches is shaping your sound. That’s why a maple Martin doesn’t sound like a rosewood Martin, and why you can’t “just EQ it later.”

Wood is organic — it grows differently depending on climate, soil, sunlight, and whether it was whispered sweet nothings by forest elves. That variation gives every guitar its own voice.

The trick is matching your voice (and playing style) with the right species.

Acoustic Guitar - Wood Back & Sides

When it comes to an acoustic guitar, the back and sides are more than just pretty panels to stare at under stage lights — they’re the framework that decides how the guitar projects, resonates, and responds to your touch. Think of them as the guitar’s lungs: the denser the wood, the longer it breathes; the lighter the wood, the quicker it exhales.

Rosewood is the big, resonant storyteller, with Brazilian rosewood delivering that legendary, complex voice and East Indian rosewood bringing deep bass and warm overtones. Cocobolo? That’s rosewood’s flashy cousin — bright, exotic, and unapologetically loud. Mahogany flips the script with a dry, punchy midrange that records beautifully without muddying the mix, while Sapele keeps things in the same family but adds a ribbon-like shimmer. Maple gives you clarity and focus, projecting your sound like a spotlight, while Koa offers a gorgeous balance between rosewood’s depth and mahogany’s punch, with Hawaiian flair to spare. Walnut starts bright and grows warmer with age (like fine whiskey), and Sycamore, with its subtle streaks, mellows the highs and lows for a smooth, understated vibe.

In short? The back and sides are your guitar’s personality. Pick wisely — they’ll either whisper your secrets or shout your truths.

  • Brazilian Rosewood

    Brazilian rosewood is one of the most coveted tonewoods, celebrated for its striking beauty and exceptional sound. Its dark brown hues, accented by black lines and touches of orange, create a luxurious, exotic look. Renowned for its tonal complexity, it offers rich overtones, deep resonance, and long sustain, balancing warmth and clarity. With powerful bass and articulate treble, Brazilian rosewood delivers a rare blend of elegance and depth, making every instrument truly extraordinary.

  • East Indian Rosewood

    East Indian rosewood is one of the most popular and reliable tonewoods, known for its durability, beauty, and versatile sound. Visually, it features a more understated grain pattern compared to Brazilian rosewood, with colors that range from dark brown to deep red and subtle purples. Tonally, East Indian rosewood is prized for its strong bass response, clear mids, and shimmering overtones, producing a rich, full-bodied sound.

  • Cocobolo

    Cocobolo is a dense, tropical hardwood prized for both its striking looks and tonal character. Known for its vivid colors and dramatic grain, it brings an exotic elegance to high-end guitars. Its hardness gives it a bright, reflective tone with pronounced treble and crisp articulation, making it especially effective for guitar backs and sides. Balanced with warmth and clarity, Cocobolo offers players a unique blend of visual beauty and brilliant sound.

  • Genuine Mahogany

    Genuine mahogany is a classic tonewood known for its warm, focused sound and balanced projection. Compared to rosewood, it is lighter in weight and density, with a lighter brown appearance and a clear, natural aesthetic. Tonally, mahogany emphasizes punchy midrange and bright treble, with a controlled bass response that makes it especially well-suited for studio recording. Its clarity and balance give mahogany guitars a versatile, articulate voice that appeals to both performers and recording artists.

  • Sapele

    Sapele is an African tonewood often compared to genuine mahogany, sharing a similar rich and warm tonal character. While it delivers a comparable sound, Sapele is known for its distinctive grain, which can feature a beautiful ribbon-like pattern with varying shades of light and dark. Tonally, it provides a powerful midrange with excellent punch, along with bright, airy trebles. This combination of classic tone and unique aesthetic makes it a popular choice for guitar builders and players.

  • Maple

    Maple is a highly popular tonewood, prized for both its striking appearance and bright, clear tone. As a guitar back and side material, it often features dramatic figured grain patterns, from flame to quilt, that create a stunning aesthetic. Its high density provides excellent sustain and a focused, articulate sound. Unlike other woods, maple produces fewer complex overtones, resulting in a direct, punchy, and transparent voice that allows the natural tone of the guitar's top wood to shine through.

  • Koa

    Straight from Hawaii, koa looks like fire trapped in wood. Tonally it’s the perfect middle ground: mahogany’s midrange, rosewood’s sustain, plus a shimmer on top. Balanced, smooth, and fingerstyle-friendly.

  • Walnut

    Walnut is a dense and resonant tonewood with a unique tonal profile. Sonically, it offers a strong midrange with a brilliant top end, much like koa, but with more emphasis in the mids. Over time, its tone tends to soften and warm up, resulting in a more prominent low-end response. Visually, walnut is celebrated for its deep, rich brown hues and distinctive grain patterns, which give guitars a natural, rugged, and elegant appearance.

  • Sycamore

    Sycamore is a lightweight tonewood that gives guitars a soft, warm voice. Its lower density absorbs some of the sound energy, resulting in a balanced tone that gently rolls off the extreme highs and lows. Aesthetically, Sycamore is noted for its beautiful, creamy white to light brown color, often featuring stunning streaks of pink, brown, or red. This combination of a mellow tone and unique, elegant appearance makes it a distinctive choice for instruments.

Acoustic Guitar - Top Woods

If the back and sides are the lungs, the top is the vocal cord — it’s where most of your guitar’s tone comes from. Strum a chord, and the top decides whether you’re singing opera or whispering a lullaby.

Spruce is the undisputed champ here. Sitka spruce is the all-rounder, capable of everything from delicate fingerpicking to full-tilt bluegrass flatpicking. Adirondack (a.k.a. Red Spruce) ups the volume and complexity, perfect if your right hand tends to get enthusiastic. Engelmann is the sensitive poet — softer, sweeter, and ideal for nuance — while European spruce adds brilliant trebles and big projection, the same species that once made Stradivarius violins sing.

If spruce is the gold standard, cedar is its moody, romantic cousin. With a darker hue and richer overtones, cedar tops are fantastic for fingerstyle players chasing intimacy over horsepower. Mahogany tops? They’re all about earthy mids and a vintage, woody vibe, while koa steals the show visually and sonically, compressing the tone just enough to add shimmer and balance.

At the end of the day, the top is your guitar’s voice. Spruce shouts, cedar sighs, mahogany growls, and koa… well, koa makes everything a little prettier.

Spruce Tops

  • Spruce

    Spruce is considered the industry standard for acoustic guitar tops, celebrated for its broad dynamic range and versatile tone. This lightweight yet durable tonewood produces a crisp, articulate sound with exceptional clarity. Visually, it has a classic look with a fine, straight grain over a creamy white or pinkish background. While some may see its balanced, straightforward tone as lacking unique character, this quality makes it a perfect, all-around choice for a variety of musical genres and playing styles.

  • Sitka Spruce

    Sitka spruce is the most common and versatile tonewood used for guitar soundboards, essentially serving as the industry standard. It’s highly sought after for its balanced and transparent tonal character. Sitka spruce tops handle a wide dynamic range with ease, responding well to both aggressive strumming and gentle fingerpicking. This dependable tonal profile, combined with its classic appearance and excellent durability, makes it an ideal choice for a variety of musical genres and playing styles.

  • Lutz

    Lutz spruce is a naturally occurring hybrid of Sitka and white spruce, offering a unique blend of their best characteristics. Tonal properties are similar to Sitka, providing a strong, broad dynamic range, but with a slight boost in harmonic richness. This makes Lutz spruce a great choice for both aggressive strumming and nuanced fingerstyle playing. Its standout feature is its remarkable consistency, ensuring a reliable and vibrant tone from guitar to guitar.

  • Eastern Red Spruce

    Eastern red spruce, often called Adirondack spruce, is a legendary tonewood known for its stiffness and high resonant quality. It is slightly heavier than Sitka spruce, which allows it to be driven harder, producing greater volume and dynamic range. This wood also provides a rich, complex tone with a strong fundamental and exceptional clarity. These characteristics make Eastern red spruce a top choice for players with a more aggressive attack and for those who seek powerful, responsive projection.

  • Engelmann Spruce

    Engelmann spruce is a softer, lighter tonewood than Sitka or Adirondack, making it an excellent choice for a responsive guitar top. Because it's less stiff, it's best for players with a lighter touch, like fingerstyle guitarists, as aggressive playing can over-compress the sound. Engelmann's tone is warm and rich, with a mature, lush quality right from the start. Its appearance is a classic creamy white, often with a consistent, straight grain pattern.

  • European Spruce

    European spruce, often called Alpine or Moon spruce, is a revered tonewood, the same species used in legendary Stradivarius violins. Sourced from various parts of Europe, it's known for its exceptional dynamic range and quick response. Tonally, it produces bright, clear trebles and a rich, warm bass, offering incredible projection. Its appearance is typically whiter than Sitka spruce, and a select variety, harvested during specific moon phases, is prized for its consistent and vibrant sound.

Other Wood Tops

  • Cedar

    Warm, dark, overtone-rich. Less headroom than spruce but dreamy for fingerstyle. If spruce is a microphone, cedar is a velvet pillow.

  • Mahogany

    Yes, you can have a mahogany top. Expect dry, warm mids and a vintage, woody vibe.

  • Koa

    Lush looks, lush mids. Koa tops add natural compression and sparkle. Think of it as tonewood Instagram filter: balanced and glowing.

Acoustic Guitar Fingerboards

These don’t shift tone quite as dramatically as the body, but you’ll notice them every time you play.

  • Rosewood: Smooth, oily, warm. A classic choice that just feels right.
  • Ebony: Dense, snappy, jet-black, with fast attack. The sports car of fretboards.
  • Richlite: Ebony’s eco-friendly doppelgänger. Consistent, sustainable, and road-tough.
  • Granadillo: Similar to rosewood, with rainbow hues in the grain. A little exotic, a lot gorgeous.
  • Katalox: Purple-tinged, dense, and bright. Ebony vibes with extra character.
