Anarchtop guitar is a hollowacoustic orsemi-acoustic guitar with a full body and a distinctive arched top, whose sound is particularly popular withjazz,blues, androckabilly players.
Typically, an archtop guitar has:

The archtop guitar is often credited toOrville Gibson,[1] whose innovative designs led to the formation of the Gibson Mandolin-Guitar Mfg. Co, Ltd in 1902. His 1898 patent for amandolin, which was also applicable to guitars according to the specifications, was intended to enhance "power and quality of tone." Among the features of this instrument were a violin-style arched top and back, each carved from a single piece of wood, and thicker in the middle than at the sides; sides carved to shape from a single block of wood; and a lack of internal "braces, splices, blocks, or bridges . . . which, if employed, would rob the instrument of much of its volume of tone."[2][3]But Gibson was not the first to apply violin design principles to the guitar. Guitar maker A. H. Merrill, for example, patented in 1896 a very modern looking instrument "of the guitar and mandolin type . . . with egg-shaped hoop or sides and a graduated convex back and top." The instrument featured a metal tailpiece and teardrop shaped "f-holes," and strongly resembled the archtop guitars of the 1930s. James S. Back obtained patent #508,858 in 1893 for a guitar (which also mentions applicability to mandolins) that among other features included an arched top, which were produced under the Howe Orme name. Another transitional design is theparlor guitar fitted with a floating bridge and tailpiece. These inexpensive instruments, manufactured by companies such asStella andHarmony, are associated with earlyblues musicians. The earliest Gibson designs (L1 to L3) introduced the arched top and increasing body sizes, but still had round or oval sound holes.
In 1922,Lloyd Loar was hired by the Gibson Company to redesign their instrument line in an effort to counter flagging sales, and in that same year theGibson L5 was released to his design. Although the new instrument models flopped commercially and Loar left Gibson after only a couple of years, Gibson instruments signed by Loar now are among the most prized and celebrated in stringed-instrument history. Perhaps the most revered instrument from this period is the F5 mandolin, but probably the more broadly influential was the L5 guitar, which remains in production to this day. The mature Gibson archtop guitar and its imitators are regarded as the quintessential "jazzbox."
Archtop guitars were subsequently made by many top American luthiers, notablyJohn D'Angelico of New York andJimmy D'Aquisto,William Wilkanowski,Charles Stromberg and Son in Boston, and by other major manufacturers, notablyGretsch andEpiphone. In Europe, companies such asFramus,Höfner,Hoyer andHagström took up the manufacture of archtops. Archtop guitars were particularly adopted by bothjazz andcountry musicians, and inbig bands andswing bands.

Gibson'sES-150 guitar is generally recognized as the world's first commercially successful Spanish-style electric guitar. TheES stands for Electric Spanish, and it was designated150 because it cost $150, along with an EH-150amplifier and a cable. After its introduction in 1936, it immediately became popular injazz orchestras of the period. Unlike the usual acoustic guitars utilized in jazz, it was loud enough to take a more prominent position in ensembles. Jazz guitaristEddie Durham is usually credited with making the first electric guitar solo, but it was ES-150 playerCharlie Christian who popularized the jazz guitar as a solo, not just a rhythm, instrument. The ES-150's top was not carved on the underside, making it unsuitable for acoustic use.
In 1951, Gibson released the L5CES, an L5 with a singlecutaway body and two electric pickups, equally playable as either anacoustic guitar or anelectric guitar. This innovation was immediately popular, and while purely acoustic archtop guitars such as theGibson L-7C remain available to this day, they have become the exception. In 1958, the L5CES was redesigned with humbucking pickups; most, but certainly not all, subsequent archtop guitars conform loosely to the pattern set by this model.[citation needed] The electric archtop was particularly popular with jazz musiciansTal Farlow,Barney Kessel andJohnny Smith.
Other manufacturers introduced electric archtop guitars, notable examples including theGretsch White Falcon and variousChet Atkins models. Some of these instruments have a distinctive "twangy" sound and were taken up bycountry music and earlyrock and roll artists such asDuane Eddy andEddie Cochran. Similar models remain popular inrockabilly.

Gibson's last innovation in archtop design was the creation, in 1955, of "thinline" models with a reduced body depth.[4] Notable thinline models include the successfulGibson ES-335, introduced in 1958, as well as theEpiphone Casino, introduced after Epiphone was acquired in 1957 by CMI, Gibson's parent company.[5] These were more feedback resistant, comfortable to hold and easier to play standing up. The first thinlines were hollow bodies. Later thinlines such as the ES-335,ES-345 and ES-355 were semi-hollow. Thinlines can be classed assemiacoustic guitars, although not all semiacoustic guitars have an arched top. Thinlines became popular with mainstream pop and rock artists during the 1960s. The ES-335 and similar guitars were taken up by, and remain steadfastly popular with, electric blues players;B. B. King's various "Lucilles" are based on the ES-335.
The 1970s and 1980s were a low point of interest in archtops, with many rock and pop (and some jazz and blues) players switching tosolid body guitars. One manufacturer for this period wasRobert Benedetto.
Interest in archtops was revived in the 1990s. Archtops had long been expensive instruments, with a level of finish and ornament to match. Boutique luthiers such asRoger Borys andBob Benedetto brought the aesthetics of the instrument to even greater heights, making them attractive to collectors, and also continuing to innovate in technical design. The Benedetto style of acoustic/electric archtop has itself been copied by luthiers such asDale Unger andDana Bourgeois. Most of the accessories (pickguard, bridge, tuner buttons, knobs, etc.) are made of wood (ebony or rosewood) instead of metal and have a clean acoustic look. It is estimated there are nearly 100archtop guitar luthiers in North America alone.[6]
Contrastingly, mass-market archtop guitars became more affordable in the late 20th century, due to a combination of low labor costs in Asian countries andcomputer numerically controlled manufacture.[7] Most major guitar marques include at least a couple of archtops in their range, albeit not necessarily manufactured at their own facilities.Ibanez sells an extensive range of archtops under theArtcore marque. TheSamick corporation sells archtops under its own name besides manufacturing for other companies. Gibson sells inexpensive Asian-made archtops under itsEpiphone brand, such as theEpiphone Dot.[8]
Renewed interest in acoustic music has also led to the revival of purely acoustic archtops, such as theGibson L-7C,The Loar Lh-600,Godin 5th Avenue and theEpiphone Century Series.
Recent technical innovations includeKen Parker's use of carbon fibre in high-end acoustic archtops, and the Godin Montrealhybrid guitar.

Archtops usually have three-a-sidepegheads and necks similar in width to a steel-string acoustic rather than an electric. High-end models traditionally have "block" or "trapezoid"position markers.
The top or belly (and often the back) of the archtop guitar is either carved out of a block of solid wood or heat-pressed using either a solid top or laminations, the latter being a less expensive construction method. The belly normally has twof-holes, the lower of these partly covered by a scratch plate raised above the belly so as not to dampen its vibration. The arching of the top and the f-holes are similar to the violin family, on which they were originally based. The contours of the arching profile are usually derived in an ad hoc fashion.[9] The tops of Gibson's archtops wereparallel braced. X-braced designs were introduced later, giving a tone closer to that of a flat-top guitar.[10]Sitka spruce,European spruce, andEngelmann spruce are most often used for the resonant tops of archtop guitars, although some guitar builders useAdirondack spruce (Red spruce), orWestern red cedar. Archtop guitars often haveCurly maple orQuilted maple backs. Full-sized archtops are among the largest guitars ever made, with the width of the lower bout in some cases approaching 19 inches (47 cm).
The original acoustic archtop guitars were designed to enhance volume, so they were constructed for use with relatively heavy strings. Even after electrification became the norm, jazz guitarists have continued to fit strings of 0.012" gauge or heavier for reasons of tone, and also preferflatwound strings. Thinline archtops generally use standard electric guitar strings.[11]
Many vibrato systems cannot be fitted to an archtop owing to the need to cut large holes in the belly to accommodate the mechanism, with the exception of theBigsby vibrato tailpiece and the long tailpiece versions of theGibson Vibrola. These vibrato systems mount on the surface of the guitar and need no body routing. Other systems have been used and trialed since this time.
Although "archtop" normally refers to ahollow-bodied, arched top instrument, some makers ofsolid-bodied guitars with carved bellies also refer to these as archtop to distinguish these fromflat top guitars. For example, Gibson refers to the standardGibson Les Paul as an archtop to distinguish it from flat top models such as theLes Paul Special andMelody Maker.
A continuum exists from purely acoustic instruments similar to the original Orville Gibson design, to solid-body designs:
Archtop 4-stringbass guitars have been manufactured since the use of electricpickups became popular. The most famous example is theHöfnerviolin bass used byPaul McCartney.Warwick makes a range of archtop 4-, 5-, and 6-stringbass guitars.Framus also makes a range of archtopbass guitars.
4-string (tenor),7-string,9-string, and12-string archtops have been manufactured.
A few luthiers[12] offer archtoppedMaccaferri guitars.
TheMohan veena is a cross between an archtop and an Indianveena.
Some electric archtops also havepiezoelectric pickups, making themhybrid guitars.
A relatively small number of ukulele makers offer instruments with flat tops but arched backs, generally of heat-pressed laminate construction with high-quality veneer; that design concentrates the uke body's internal resonance upward toward the sound hole, "like a parabolic mirror," according to the German seller RISA, whose Koki'o brand line of ukuleles all feature arched backs.
