These first three-coned instruments were called tricones, and they immediately caught on with the Hawaiian guitarists that were very popular in this era, like Sol Hoopii. The tone of these guitars could be almost liquid, with complex overtones, a reverberating quality, and a lot of sustain. In response to the Great Depression, National introduced a less complex design that was more cost-effective to build. These more affordable guitars used one large cone, with a small bridge attached to the top of the cone, called a biscuit.
A spider bridge, as the design came to be known, produces a sweeter and more sustaining sound than a biscuit-style resonator, but not as rich as a tricone. Spider bridges found favor first with country and later with bluegrass musicians. The less popular of the three main types is the biscuit design, which uses a single resonator that is attached to the underside of the bridge via a biscuit shaped wooden disc for structural support.
Whilst there are many common practices for matching neck shape, body material and resonator design, there are many differing combinations which can be found and used for a variety of musical genres. As these music genres progress and borrow from each other, it is increasingly common to see a blues guitarist borrowing from country and playing lap steel style, or visa versa.
With the additional rise of folk inspired acts such as Mumford and Sons making their way into popular music, the trend to break these rules is sure to continue. As such we would advice to choose the style of resonator that suits the music you play and how you play it best, but also to be open to trying something different.
It certainly is confusing! Do you have these in your Lancaster store? Hi Glenn A resonator is basically an acoustic guitar which is self amplified in a different way. These are part of the large metal section of the instrument. Buyers Guides. Acoustic Guitars Bluegrass Blues Resonator. This design works especially well with metal-body guitars, like the kind the old bluesmen used to cut through the squall of noisy juke joints.
It tends to create a booming fundamental tone. The trade-off for that volume is less harmonic complexity. In wooden bodies, this design is not quite as thunderous. The tricone. Yep—this intriguing design has three cones and a T-shaped bridge that helps get the string vibrations to all of them. The saddle on a tricone straddles a leg of the T, and these cones also face downward. Since more energy gets transmitted to a more complex cone array, tricone models tend to be more harmonically complex and produce more overtones than single-cone-with-biscuit guitars.
And tricones sound really sweet for slide. Typically, this design is found in metal-body guitars. And finally, along comes the spider. In the spider bridge with single-cone design, the cone has an interior raised section.
The aluminum bridge makes contact with the cone at its edges and the apex of its raised center, which has a slot that holds a wooden saddle. More contact equals more transmission of string vibration. Oh yeah—and the cone faces forward, like the speaker in a guitar amp. Its sounds are projected out of, rather than into, the body. This design is typically employed in wood-body resonator guitars, and these guitars often have specially designed soundwells to add to the sonic projection.
Between that, the forward-facing cone, and the high-contact spider bridge, these are loud suckers. And they often have a tonal character that could be described as honking. They are the first distinctly American variation on the guitar—born in the U. And before you go off to explore resonators on your own, I would like to say that John Dopyera should be considered the Thomas Edison of the guitar industry.
His legacy includes not only resonator guitars, but the foundation on which the Valco family of products were established … and more, with connections to the Rickenbacker and Fender legacies. Not bad for an immigrant who kicked it all off by wanting his own little instrument repair shop. So maybe, in some way, the sound of the Dobro is also the sound of the American Dream. Rig Rundowns.

A resonator guitar is an acoustic guitar , and can even be similar in shape, although the shape has little to do with sound on a resonator guitar.
It lacks the traditional soundhole on an acoustic, and instead, it has a round, perforated plate cover in its place. It will feature two sound holes on each side of the fingerboard, either in round circles or f-style holes. The plate has a built-in bridge where string vibrations are carried through some form of system to be amplified by a cone or several cones, the resonators.
Resonator guitars were designed to be louder than acoustic guitars and they produce a very distinguished banjo-like sound often sought after by bluegrass, blues, folk, and country players. So, where does the dobro come in?
The dobro is an actual guitar that was created by the Dopyera Brothers, one of whom was the inventor of the resonator guitar. The string vibrations are transmitted via the center-set bridge and resonated throughout the perforations on the plate and the sound holes through the eight-legged spider system that reverberates through the inverted cone design.
