The Jazz Guitar Amp And Guitar

By Leticia Jensen


Jazz guitars were conceived in the early 1930s due to the need to use amplification in order to increase the volume of conventional acoustic guitars in a live setting so it can be heard more clearly. Very few instruments have had a greater influence on the evolution of music since the start of the 20th century. The earliest forms of jazz guitars were acoustic but by the 1940s, musicians were playing with either a hollow body acoustic or electric guitars along with a jazz guitar amp.

Probably the most recognisable type of guitars used for this type of music is the archtop. It has a large hollow sound box, magnetic pickups, floating bridge and violin style f shaped sound holes. These guitars are also known as hollow body guitars and have been available to purchase since the 1950s from famous manufacturers.

Jazz guitar involved several playing styles, the most common being blowing, comping and soloing. Blowing refers to improvising over the top of a chord progression with phrases and ornaments. Comping is the playing of extended chords while another musician solos or plays a melody. Walking basslines often have walking basslines and improvisation will make use of modes, scales and arpeggios.

Jazz can be performed on of the world'd most popular guitars but the hollowbody or archtop is the one most associated with jazz. It has the classic "warm", jazzy tone that people recognise instantly. Leading manufacturers, such as Epiphone, Gibson, Stromberg and D'Angelico manufacture hollowbody guitars to very high quality standards and they are also very popular for rock and pop music. The hollow body has a spruce top and maple back. The sides are made of one piece of wood form into an arch giving the instrument its name "archtop."

The beautifully jazzy tone is best produced with a hollowbody archtop, due to its magnetic pickups and hollow body. Although, the desired "warm tone" from these guitars is best combined with a good amplifier that has been designed specifically for this kind of music.

Tube amps may have have a great tone and a far more musical overdriven sound compared to solid state amps, but they are very heavy and they are difficult to maintain. They also suffer from more noise than solid state amps and are more expensive.

The Roland JC-120 Chorus is one of the more popular amps. It was first released in 1975 and was one the first that came with effects built in. Many of the great guitarists used the Roland, including George Benson, Pat Martino, Larry Coryell and many other legends in this type of music.

There are several excellent amps produced by Fender. These include: The Fender King, Fender Hot Rod Deluxe, Fender Blues JR and the very popular Fender Jazzmaster stack with amplifier head. Each one of these amps does a fantastic job of creating a beautiful and jazzy tone, especially when combined with a classic archtop or hollowbody.
