The electric guitar’s body wood is a toneful heart and soul resonating under those strings. Alder or mahogany, maple or ash – luthiers have used them all. Yet the perennial debate remains, which builds the best sounding plank?
This epic tonewood clash examines the stories, science and sound behind two all-time classics – mahogany and alder. Lives have been lived for the guitar. These great woods gave those lives voice.
So strap in, turn up, and get ready to obsess. We’re going on a tonal odyssey.
A Brief History of Mahogany and Alder Guitars
Before rock’n’roll, mahogany and alder had long lives. The history of these timbers tells stories of guitars yet to come.
Mahogany – Timber of Empire
Indigenous to Mexico, Central America and the West Indies, mahogany fueled colonial expansion. Its strength, workability and luster made perfect ship masts.
Europe’s 17th century naval powers – Spain, France, England – established West Indies colonies to feed their mahogany appetite. The wood built empires upon the sea.
Mahogany’s shipbuilding days ended as steel hulls replaced timber. But a new empire emerged – the guitar.
Orville Gibson chose mahogany to launch his instruments in 1902. Lloyd Loar expanded its use for Gibson’s early archtops of the 1920s. The association of mahogany with Gibson guitars continues today.
From mast to soundboard, mahogany’s resonance and beauty transferred seamlessly to guitars. Its empire expanded from the sea to the stage.
Alder – Punk of the Pacific Northwest
Alder trees thrive along North America’s Pacific coast – from Alaska to Baja California. Native Americans traditionally used alder for everything from dwellings to dugout canoes.
Yet alder remained obscure until electric guitars adopted it. Fender pioneered alder plank bodies in the 1950s. Its light weight and snappy tone boosted Fender’s rock and roll-friendly image.
Alder came into its own during the 1980s punk explosion. Indie guitarists prized its snarling punch and defiant lack of figured beauty.
Grunge superstars like Kurt Cobain continued alder’s punky pedigree into the 1990s. Fender’s mass adoption branded it a workingman’s rock wood.
While mahogany sailed with Spanish Conquistadors, alder hung out with skate punks. The woods’ contrasting histories echo through their divergent tones.
Physical Properties – Density Defines Tone
Mahogany and alder woods have distinct physical properties that influence their sound. Science reveals truths behind the tone.
Mahogany – Dense and Rigid
- Species – True mahoganies belong to the Swietenia genus. Khaya wood is often sold as African mahogany.
- Density – Ranges from 550-850 kg/m3 when dried. Denser than alder.
- Color – Varies from pale pink to dark red shades. Reddish-brown is most common.
- Grain – Typically straight or interlocked. Rarely figured patterns.
- Weight – Moderately heavy and rigid due to density. Stabilizes guitar tuning and intonation.
Mahogany’s density adds sustain and richness. Its rigidity enhances attack and playability. The result is a balanced, responsive tone.
Alder – Lightweight Resonance
- Species – Red alder (Alnus rubra) dominates, also known as Pacific Coast alder.
- Density – Ranges from 290-450 kg/m3 when dried. Lower density than mahogany.
- Color – Reddish-brown to pale tan. Occasional mineral streaks.
- Grain – Fairly straight grain with a porous look. Prone to knots.
- Weight – Very lightweight and resonant when dried. Comfortable for playing over long gigs.
Alder’s lower density aids vibration and resonance. This enhances projection and volume. The wood also remains light on the player’s shoulders.
The Sound of Tonewoods – Science Meets Art
The molecular structure of wood defines its sound at microscopic levels. But subjective qualities like clarity or bloom take on an artistic, poetic nature.
Decoding Mahogany’s Tone
- Warm and rounded tone – Mahogany’s density adds bass and compressed mids.
- Natural compression – Evens the EQ response across lows, mids, and highs.
- Complex overtones – Strong fundamental tones seasoned with harmonics.
- Singing sustain – Rigidity carries notes with a slow, even decay.
- Quick attack – Fundamentals sound tight before opening up.
- Mid-range focus – Distinct spike around 350-500 Hz range.
To fans, mahogany feels soulful and versatile. The classic Les Paul owes much of its mojo to tuned mahogany.
Describing Alder’s Character
- Bright and crisp – Alder’s resonance accentuates treble snap and cut.
- Scooped mids – Mid-range takes a backseat to extended highs and lows.
- Strong projection – Low density propagates volume and breathing room.
- Quick decay – Notes have a short, lively sustain before fading out.
- Percussive attack – Emphasizes transients for rhythmic chunk.
- Clarity and note separation – Each string articulates individually.
Alder wins praise for its shimmering glassy tones. Fender’s seedling Stratocasters grew strong on resonant alder roots.
Put to the Test – Electric Guitar Models
While specs tell part of the story, great guitar tones take flight fully built. Let’s examine key guitar models to hear mahogany and alder in action.
Mahogany Guitars – Thick, Singing Tone
The mahogany family tree sprouts many diverse species of guitar. From Gibson to PRS, mahogany represents a versatile vintage tonewood.
Gibson Les Paul Standard
The Les Paul Standard sets a gold standard for mahogany tone. With humbuckers, mahogany’s thick midrange and sustain give the Les Paul its legendary mojo.
The SG offsets Les Paul girth with a lighter dose of mahogany. Angled mahogany wings retain thickness while improving playability and comfort.
PRS Custom 24
For many players, PRS perfects the mahogany recipe. Carlos Santana’s signature model uses patterned mahogany for a sweetly singing lead voice.
Alder Guitars – Bright, Punky Snarl
Alder forms the foundation for many classic Fender guitars. When twang and spank are the need, alder delivers the goods.
An alder plank shaped a timeless electric guitar icon. The Stratocaster’s punchy bark and bell-like bite come courtesy of resonant alder.
Twangy, snarling country tones drive the Tele’s alder body. Focused bridge pickups and snappy decay give Tele riffs their signature snap.
Jangly indie rock finds its voice through the Jazzmaster’s transparent alder sustain. From surf to shoegaze, alder dresses the part.
Durability and Sustainability
Beyond sound, a guitar’s tonewood must withstand string tension and routine playing. Environmental issues matter too.
Mahogany Holds Fast
- Density adds strength – Mahogany stands up well to routine dings. Few wood grains exceed its stability under string tension.
- Cracking resistance – Rigidity makes solid mahogany guitars less prone to finish checking.
- Neck joint stability – Works well for both bolt-on and set mahogany necks.
- Rot resistance – Natural oils repel fungus and hold tuning in humid climates.
Mahogany sets the stage for sustainable harvesting and reforestation efforts. Initiatives like the FSC seek to balance use with ecological needs.
Alder Hangs Tough
- Softness risks dings – Alder’s low density doesn’t resist dings as well as denser woods. Its finishes require more care.
- Lightness resists cracking – Flexibility of low-density alder minimizes finish checking issues.
- Stable under tension – Grain strength handles string tension despite its softness.
- Prone to knotting – Knots and grain irregularities more common than in mahogany.
Alder is plentiful across western North American forests. Yet its softness can’t equal mahogany for flawless aging.
Sound, Science and Soul
Tonewoods mix science and sentiment in a sonic stew. Beyond density curves lie mojo, myth and inspiration.
Mahogany – Soul Power
For many, mahogany hits a tonal sweet spot. Its balanced sound layers rock muscle with vintage warmth Mahogany gives the Gibson Les Paul its deep roar, while PRS models sing with sustain. Slash, Santana, Jimmy Page – mahogany carries the torch of tone.
Yet science tells only part of mahogany’s story. Mystique and lore spin darker tales, from voodoo spells to haunted tone. Some believe a guitar’s wood absorbs energy from players past. Mahogany’s rich history makes those myths resonate.
Like the best mojo, mahogany mixes truth and tall tales. Science and soul give the wood’s tone life.
Alder – Bright and Light
Fender stamped alder’s sonic signature across surf, country, and punk. The Strat, Tele and Jaguar owe alder their jangly spirit.
With density low, alder vibrates freely as a lively, resonant tonewood. Its twangy cluck and shimmering sustain beam out punchy, articulate tone.
Yet alder’s punky vibe also comes from its everyman roots. It lacks mahogany’s mystique or figured beauty. Alder keeps honest company with working musicians seeking truth, not frills.
That stripped, honest sound seeded alder’s rise from lumber barges to rock and roll fame. Its resonance rings out across genres without pretension. If mahogany sings the blues, alder calls square dances with raw exuberance.
Alder’s lightness in weight and spirit strums a timeless sound. Its tuneful timber builds guitars to play loud and proud.
