| Mahogany | When used as a top, mahogany  has a relatively low velocity of sound (compared to other top woods),  considerable density and a low overtone content producing a solid tone,  and responds best at the upper end of the dynamic range. Mahogany-topped  guitars have a strong "punchy" tone that is well suited to country  blues playing. When considered for back and sides, mahogany has relatively high velocity of sound, which contributes much overtone coloration. While rosewood guitars may be thought of has having a metallic sound, mahogany guitars sound more wood-like. The harder, denser examples of these woods can take also on the characteristics of the rosewoods. Mahogany back and sides tends to emphasize the bass and the treble. Mahogany necks help to create a warmer, more "woody" tonal range. The same holds true when mahogany is used as bridge material.  |                                  
| Koa | Koa has been used for  soundboards since the1920s. This hardwood has a relatively low velocity  of sound, considerable density and a low overtone content. Therefore, it  tends to produce a solid tone that responds best at the upper end of  the dynamic range. Koa has a somewhat more "midrangey" tone that works  well for playing rhythm and truly shines in guitars made for  Hawaiian-style slide playing. For back and sides, Koa tends to behave much like mahogany in terms of adding tonal coloration, but its emphasis is again more in the midrange.  |                                  
| Brazilian Rosewood | All the rosewoods contribute to  tonal coloration. Brazilian rosewood is known for its high sound  velocity and broad range of overtones, and is also characterized by  strength and complexity in the bottom end and an overall darkness of  tone in the rest of the range. Strong mids and highs also contribute a  richness of tone to the upper registers. Rosewood guitars also have a  pronounced reverberant-like tone quality, caused by audible delays in  the onset of certain harmonics. Brazilian rosewood has tremendous  clarity in the bottom end and sparkle in the top.  When used for necks, Brazilian rosewood adds sparkle and ring.  |                                  
| Indian Rosewood | Indian rosewood is  also known for high sound velocity and broad range of overtones,  strength and complexity in the bottom end and an overall darkness of  tone in the rest of the range. Strong mids and highs also contribute a  richness of tone to the upper registers. Indian rosewood has a thicker,  more midrange overall coloration. When used for necks, Indian rosewood can help fatten up the midrange.  |                                  
| Sitka Spruce | Spruce is the standard material  for soundboards, the most commonly used species being Sitka. Its high  stiffness combined with the lightweight characteristics of most  softwoods, makes it a natural for high velocity of sound. A strong  fundamental-to-overtone ratio gives Sitka spruce a powerful direct tone  capable of retaining its clarity when played forcefully. This makes  Sitka an excellent choice for top wood for players whose style demands a  wide dynamic response and a robust, meaty tone. On the other hand, the  lack of complex overtones in Sitka can produce a somewhat thin sound  when played with a light touch - of course, depending upon the design of  the guitar and the other choices of wood in its construction. |                                  
| Red Spruce | Red spruce is relatively heavy,  has a high velocity of sound, and the highest stiffness across and along  the grain of all the top woods. Like Sitka, is has a strong  fundamental, but also a more complex overtone content. Tops produce the  highest volume, yet they also have a rich fullness of tone that retains  clarity at all dynamic levels. In short, red spruce may well be the Holy  Grail of top woods for acoustic steel-string guitars. |                                  
| Maple | Maple, as a result of its  greater weight and lower sound velocity, can be downright flat sounding,  a blessing in disguise when a guitar is amplified at high sound  pressure levels. This is why maple is the wood of choice for electric  guitar tops. West coast big leaf maple is the softest and lightest of  the maple family, with a wood grain that resembles waves. Aside from a  visually breathtaking pattern, the wavy fibers of "curly" maple reduce  the long grain stiffness and vibrate more freely. (This is the secret to  the bright, clear powerful sound of the Parker Fly, a solid-body guitar  made with a curly maple body.) In acoustic guitar use, different species of maple, such as big leaf, sugar, and bearclaw tend to be more acoustically transparent due to their lower velocity of sound and high degree of internal damping. This allows the tonal characteristic of the top to be heard without the addition of significant tonal coloration. Maple necks can impart a bright "poppy" tone that can do much to reinforce the top end of a large-bodied guitar.  |                                  
| Alder | Alder is a lightweight wood that  is highly resonant, producing a full rich tone. When used for solid-body  construction, alder provides a very good low end and midrange with the  best performance in the lower mid range. Alder also exhibits good  high-end characteristics and sustain. |                                  
| Poplar | Poplar is a stringy, dense, yet lightweight hardwood that is unusually resonant. Poplar, when used in solid-body electric guitars, has an exceptionally crisp sound, often described as "spirited" and "bouncy" - even "funky." Poplar guitars are ideal choices for players who favor single-coil snap and clean sound. | 
| Basswood | Basswood is light, stiff, and  stable, which makes it particularly effective for necks and bass  instruments thanks to its excellent low- end response. |                                  
| Ebony | Ebony, the traditional material found on the necks of violins, classical guitars, and high-end steel strings, has the lowest velocity of sound of all the woods commonly used and has definite damping characteristics. While not a problem for large-bodied guitars made of red spruce or Brazilian rosewood, it may be something to consider when designing smaller guitars, particularly those using less resonant tonewoods for tops and backs. |

ACOUSTIC GUITAR'S WOODS
THE LES PAUL.... GUITAR STORY

 During the 1930s, inventive individuals experimented with guitar                 bodies made from a solid piece of wood rather than soundboards                 over a hollow chamber—partly for ease of fabrication, partly                 to prevent feedback. 
One of the most prominent innovators was Les Paul. He made this                 guitar by taking a 4x4-inch solid block of pine, fitting it with                 two homemade electronic pickups, and then gluing on the halves                 of a hollow-body guitar to make it look slightly more conventional. 
 Around 1946, Paul took his "log" idea to Gibson.                 Although the company did not use his design as a prototype, it                 did work with him and use his name to promote its first line                 of solid-body guitars in the 1950s
THE STORY OF THE BLACK STRAT (DAVID GILMOUR
History of David Gilmour’s Black Fender Stratocaster
The  black Strat as it looked in 1976 following Gilmour's substitution of  the black DiMarzio FS-1 pickup. He added the neck with rosewood  fretboard in June 1972, replacing the original maple neck.
The  history of Pink Floyd has been told many times but never in the way  that Phil Taylor tells it. His book, Pink Floyd, The Black Strat, A  History of David Gilmour’s Black Fender Stratocaster, is a real-life rock and roll  story filled with color and excitement, told through the vicissitudes  and fortunes of a single musical instrument. The instrument in this  instance is a black Fender Stratocaster belonging to David Gilmour, and the story is one of the greatest in the annals of classic rock:  the Floyd’s meteoric rise to popularity in the Seventies, their  enduring appeal over the decades and historic reunion in 2006 to perform  at the Live 8 benefit concert in London’s Hyde Park.
The black Strat was Gilmour’s main ax for the four blockbuster albums that form the zenith of Pink Floyd’s career: The Dark Side of the Moon, Wish You Were Here, Animals and The Wall. Gilmour played the instrument at countless Floyd concerts down through the years, including Live 8, and it has figured on the guitarist’s three solo albums to date.
Phil  Taylor got to witness all of this from a privileged perspective. He has  been Gilmour’s guitar tech since 1974, also serving as Pink Floyd’s  general equipment manager at various periods. These days, Taylor also  manages Gilmour’s recording studio, Astoria, located in a houseboat on  the River Thames, and Pink Floyd’s vast equipment warehouse. Along with  all this, he served as production director for Gilmour’s last solo tour  and Live 8.
Taylor had never planned to become an author, but when the Fender Custom Shop  set about creating a replica signature model of Gilmour’s black Strat,  Taylor began to research the instrument’s history to help Fender put  together some documentation to go with the signature model. That  research eventually grew into a book.
“A friend of mine [Langley  Iddins] who is a very good book designer suggested I turn it into a book  and he offered to lay it out for me,” Taylor explains. “Which hadn’t  occurred to me. I thought, ‘Too much effort. I haven’t got the time to  do that.’ But to cut a long story short, he talked me into it.”
Longtime Pink Floyd art director Storm Thorgerson, the man responsible for the iconic cover art for discs like Dark Side, Wish You Were Here and Animals,  volunteered to design the cover for Taylor’s book, in which the black  Strat is seen on a northern Arizona cliffside, amid sweeping contours  carved in the reddish stone by wind erosion. In all, it’s a handsome  coffee table paperback. But the one person initially reluctant to get  behind the idea was David Gilmour himself.
“He said, ‘Why do a book on that?’ It’s only an ordinary guitar  I bought at Manny’s,’” Taylor says, referring to the famed New York  City guitar shop. “And that’s the way he’s always treated it.”
But  the ordinariness of the instrument is what makes the story poignant in a  populist kind of way. It could have been anyone’s guitar. It started  out as a 1969 Stratocaster, serial number 266936, which  means it’s from Fender’s CBS era—not the most desirable period in  Fender history. And indeed Gilmour purchased it at Manny’s Music in  1970, as a replacement for a Strat stolen a few weeks earlier in an  equipment heist that cleaned out Pink Floyd’s equipment truck. It was,  in essence, an emergency purchase. In the years that followed, the  guitar became Gilmour’s main workhorse. He took it on the road with him,  swapped pickups and necks, and drilled holes in the body to accommodate  various add-on devices. He once called it his “bodge-up guitar,” the  one he hacked up for experiments.
“The guitar was never treated with any reverence at all,” Taylor says. “It was just a working tool.”
Taylor’s  book lovingly details all six neck changes the guitar went through over  the years, plus numerous replacement pickups, hardware change-outs and  other modifications. We learn not only on which legendary Floyd tracks  the guitar was played but also the exact configuration of the guitar at  the time each track was recorded. In addition, Taylor elaborates on the  gigs at which the guitar was employed, detailing the dates, audience  tallies, set lists, press reviews and other train spotter trivia that  seem so endlessly fascinating to the hardcore Floyd fan base. A few  other Gilmour guitars enter the narrative at various points but  mentioned only in relation to the black Strat. Gilmour’s vast guitar  collection is the stuff of legend, but The Black Strat maintains a tight  focus on the titular instrument.
By the time Taylor joined the Pink Floyd team in 1974, the guitar had earned its keep on the Floyd albums Atom Heart Mother; Meddle, Obscured by Clouds and Dark Side of the Moon,  and at numerous live shows. Gilmour had wielded the black Strat on the  all-time favorite Floyd instrumental recording “Echoes” and used it to  play two of the three solos on the band’s Dark Side of the Moon  hit “Money.” By the time the instrument came into Taylor’s care, it had  already been heavily modified and definitely had experienced more than a  few trips around the block.
“It  was pretty chipped about, actually,” Taylor recalls. “It hadn’t been  looked after. I can remember, early on, getting a black felt-tipped pen  and just coloring in some of the chips on it, ‘cause it looked so bashed  around the edges—bare wood showing in various places. I remember just  trying to tidy it up a bit.”
For Taylor, working with the  gentlemanly, impeccably mannered Gilmour has been a dream gig. “I don’t  know if David’s ever even shouted at me,” Taylor says. “He’s very laid  back. Very restrained.”
And he knows his way around guitars. In  the earlier days, Gilmour performed all modifications to the black Strat  and his other instruments. “These days, he won’t mess about with his  guitars too much,” Taylor says, “although he will pick up a screwdriver  and alter the intonation or pickup height if needed. He’d never think  twice about doing something like that. He had done a bit of woodworking  as well, in his spare time, as a hobby. So he’s not afraid of delving in  there.”
Gilmour had a DiMarzio DF1 pickup installed in the black  Strat’s bridge position just in time for the sessions that produced  1977’s Animals album. And in 1978 he had luthier Grover Jackson  at Charvel fashion a custom maple neck for the guitar. Thanks to  Taylor’s book, we learn that Gilmour paid the not-so-princely sum of  $175 for the neck. We can even read the original purchase order and  invoice.
The  black Strat was outfitted with this neck when Gilmour laid down his  landmark guitar solo for the Floyd classic “Comfortably Numb” during  sessions for The Wall album at Super Bear studios in France. But by the time the band embarked on the legendary tour for The Wall, the guitar had morphed again and sported a new custom Seymour Duncan pickup in the bridge position.
And so it goes. A Kahler tremolo bridge was added in ‘83 and also a new 22-fret Charvel neck. Gilmour played the guitar in this configuration on his second solo album, 1984’s About Face.  Shortly afterward, however, the instrument fell out of favor. During  the 10-year period from 1986 to 1996, it was on display at various Hard  Rock Cafe locations, a humble fate for a guitar with such an esteemed  pedigree. Thanks to Guitar World for the report.
The black Strat as it appears today. The black pickguard was added in the summer of 1974 and the recessed toggle switch fitted in 1978. Other changes include a short 4 1/4-inch tremolo arm and a white Seymour Duncan SSL-1 bridge pickup. The other pickups are original. (inset) Gilmour with the black Strat 1971.

In 1976, Gilmour installed a black DiMarzio FS-1 pickup in the bridge position, replacing the original stock Fender pickup (Shown above). The guitar was used in this configuration for the recording of Animals and the subsequent tour.
