Resonator guitar

A resonator guitar or resophonic guitar is an acoustic guitar whose sound is produced by one or more spun metal cones (resonator

Resonator guitars were originally designed to be louder than conventional acoustic guitars which were overwhelmed by horns and percussion instruments in dance orchestras. They became prized for their distinctive sound, however, and found life with several musical styles (most notably bluegrass

 to manufacture resonator guitars under the brand name National. The first models were metal-bodied and featured three conical aluminum resonators joined by a T-shaped aluminum bar which supported the bridge, a system called the "tricone". Wooden-bodied tricone models were originally produced at the National factory in Los Angeles, California. These models were called the "Triolian", however only 12 were made and the bodies meant for tricones were changed to single cone models, but the name remained.

Dobro

In 1928, Dopyera left National to form the Dobro Manufacturing Company with his brothers Rudy, Emile, Robert and Louis, Dobro being a contraction of Dopyera Brothers' and also meaning "goodness" in their native Slovak language

. Dobro released a competing resonator guitar with a single resonator with its concave surface uppermost, often described as bowl-shaped, under a distinctive circular perforated metal cover plate with the bridge at its centre resting on an eight-legged aluminium spider. This system was cheaper to produce, and produced more volume than National's tricone.

National biscuit

National countered the Dobro with its own single resonator model, which had previously been designed by Dopyera before he left the company; while also continuing to produce the tricone design which many players preferred for its tone. Both the National single and tricone resonators remained conical with their convex surfaces uppermost; the single resonator models used a wooden biscuit at the cone apex to support the bridge. Both companies at this stage were sourcing many components, and notably the aluminium resonators themselves, from Adolph Rickenbacher

Other National instruments

After the formation of the National Dobro Corporation, the term 'National' was often used to mean an instrument with a non-inverted cone, to distinguish these designs from the inverted-cone 'Dobro'. Makers particularly used it for single-cone biscuit designs, as the relatively elaborate and expensive tricone was for some time out of production. Players and collectors also used the term for the older tricone instruments, which despite their softer volume and rarity were still preferred by some players.

In 1942, the National Dobro Corporation, which no longer produced Dobros or any other resonator instruments, was reorganized and renamed Valco

Czech Republic

In the late 90's Amistar, a Czech Republic manufacturer, began marketing tricone resonator guitars.

Australia

Wayne Acoustic Guitars produced a spider bridge resonator guitar in the '40s and '50s in Australia. They were crudely made out of what was at the time cheap Australian timber using a tone ring rather than a tone well but their biggest problems were no neck reinforcement and a very different pressed (rather than spun) cone. This is often called a pillow cone due to the shapes pressed into the face to strengthen the cone. Many examples exist today and if the neck is straight and a good cone is used can give a reasonable sound. As of 2010 Don Morrison is producing highly regarded resonators under the Donmo brand name.

Asia

Many Asian brands such as Johnson, Recording King, Republic Guitars and Rogue also produce or import a wide variety of comparatively inexpensive resonator guitars. Johnson has also produced resonator ukuleles and mandolins.

South Africa

A company called Gallotone in South Africa is also known to have produced resonator guitars in the 1950s and '60s.

Playing

Resonator guitars are popularly used in bluegrass music and in blues. Traditionally, bluegrass players used square necked Dobro-style instruments played as a steel guitar while blues players favored round-necked National-style guitars, often played with a bottleneck. However, some contemporary players disregard these stereotypes and use resonator guitars in a wide variety of musical contexts.

Styles and positions

The resonator guitar is most often played as a lap steel guitar, and the more common square necked version is limited to this playing position. Square neck instruments are always set up with the high action favored by steel guitar players, and tuned to a suitable open tuning.

The round necked version is equally capable in either lap steel or Spanish guitar position. It may be set up with a variety of action heights, ranging from the half inch favored for steel guitar (making use of the frets almost impossible) to the small fraction of an inch used by conventional guitarists. A compromise is most common, allowing use of a bottleneck on the top strings but also use of the frets as desired, with the guitar played in the conventional position.

Many different tunings are used. Some square neck tunings are not recommended for round neck resonator guitars, owing to the high string tension required, which in turn requires the stronger square neck. Slack-key guitar
Slack-key guitar
Slack-key guitar is a fingerstyle genre of guitar music that originated in Hawaii. Its name refers to its characteristic open tunings: the English term is a translation of the Hawaiian kī hōalu, which means "loosen the [tuning] key"...

Varieties of resonator guitar

Single resonator guitars with a bowl resonator and spider (Dobro style) are often heard in bluegrass music, while tricone (National style) instruments are still preferred by many blues players. Single-resonator biscuit (also sometimes called National style) instruments are also currently produced, and give a different sound again.

Many bluegrass players prefer wooden bodies, blues players either metal or wood. The early metal-bodied instruments were generally of better quality than the earliest wooden-bodied ones, but this may not be the case with more recent instruments. Metal bodies may be brass, aluminum or steel. Fiberglass has also been used as a body material, and a marble
Marble
Marble is a metamorphic rock composed of recrystallized carbonate minerals, most commonly calcite or dolomite.Geologists use the term "marble" to refer to metamorphosed limestone; however stonemasons use the term more broadly to encompass unmetamorphosed limestone.Marble is commonly used for...

 bodied resonator guitar is commercially available. Both metal and wooden bodies are often painted, or wooden bodies may be stained or lacquered, metal bodies may be plated or plain.

Bluegrass players tend to use square necks, while blues players tend to prefer round necks. Square-necked guitars give a slightly greater variety of possible tunings, while round-necked guitars give a much greater variety of playing positions.

Single resonator instruments can have round sound holes with screens, or round sound holes without screens, which many players used to remove to improve the bass response. They can also have f-holes, often with gauze screens that are also sometimes removed but have an important function in strengthening the belly particularly if the body is of wood.

An enormous number of combinations are possible, most can be found either on old or new instruments or both, and many styles of music can be played on any resonator guitar.

Electric instruments

Although the original aim of the resonator was increased volume, some modern instruments incorporate electric pickups, and players add pickups to non-electric instruments, and use the resonator purely for its distinctive tone. As the resonator is far more sensitive to audio feedback
