A guitar amplifier is an electronic device which is used to amplify the signal produced by a guitar. The amplifier converts the electronic signal from the musical instrument into a more powerful electronic signal. We can use the amplifiers to modify the instruments tone by adding electronic effects. Guitar amplifiers can be classified into two groups: simple and combination amplifiers. A simple amplifier consists of a wood or metal cabinet which contains only the amplifier circuits, while the ‘combo’ amplifier contains both the amplifier and one or more speakers. Usually, guitar amplifiers have two amplifying circuit stages, and some others have electric circuits used for tone-shaping.
There are four types of guitar amplifiers: solid state, tube, hybrids and modeling. Solid state amps (analog amps), use transistors for their power sections. They are reliable and rarely need repairs.
Tube amps have a warm, fat tone distortion. They usually sound louder than solid state amps of the same wattage. In this type of amps, tubes need changing occasionally.
The modelling amps, or digital amps, use digital processors to simulate the sound of old-fashioned tube technology. Modeling amps are programmable and they put the sound of various amps in one box. The last type of amplifiers, the hybrid amp, combines the best of each type of amp into one package.
The first amplifiers for electric instrument were not adapted for use with electric guitars. The earliest examples of guitar amplifiers appeared in the early 1930s. From the beginning, guitar amplifiers were used to amplify only acoustic guitar. Then, during the 1940s, electronic amplification of guitar was widely popularised and used by many.
