resophonic 1What is a resophonic guitar?

The “resophonic guitar” was born in the mid-20’s, starting from the search for a greater volume in the traditional guitar, an instrument that lacking amplification means, passed almost unnoticed before the others. This artifact has left a deep imprint in styles such as blues, country, bluegrass or hawaiian music, but has gone almost unnoticed in other styles such as swing or jazz (I recommend listening to Oscar Alemán). Its boom was brief as approximately 10 years later began to commercialize with success the first electric guitars and their amplifiers…
At present they are, and we are, many musicians who have been captivated by the sound and uniqueness of an instrument without equal that can not be forgotten…

resophonic 2And… how it differs from “conventional guitar”?

Unlike a normal acoustic guitar, its body can be made of metal or wood (there are also some old models of bakelite) and has a mechanical amplification system consisting of a metal cone located inside the body exercising speaker.
There are several types:

SINGLE CONE: This class has a single cone that can be concave or convex and are called, referring to the type of bridge that communicates the strings with the cone, “spider bridge” and “biscuit bridge” respectively.

TRICONE: three convex cones. The ropes rest on a bridge that communicates to the three cones called “t bridge”.

Finally, another feature in these instruments is the mast that can be curved “round neck” as in conventional guitar or square neck, used to play with the guitar “back”, leaning on the legs, generally with a “slide” (western swing, country and hawaiian music).
