Guitar amplifier kits involve the components that go into boosting a guitar’s sound to an audience. Guitar amps require a preamp that precedes the power amplifier stage. There are a few popular ways to amplify a guitar: through solid-state guitar amps, tube guitar amps, and PA systems.
Solid-state guitar amplifier kits are the most inexpensive guitar amps. They can produce the sound of an acoustic guitar, electric guitar, or keyboard through a loudspeaker. The musician can modify the sound by using guitar pedal effects and EQ frequencies on the amp. Many of these amps also come with multiple channels for various tones.
Tube guitar amplifier kits, or tube amps, often provide superior sound to solid-state amps. They are used by most professional guitarists and touring musicians. They were also the essence of The Beatles vintage guitar tone along with many other rock legends.
These kits use vacuum tubes, which increase the power of a signal. Thus, they are far louder than solid-state amps. This amplifier has a power switch and a standby switch. It is vital to turn the power on for one or two minutes before turning off standby as the tubes need time to warm up to avoid being blown. These valve amplifiers are also used for satellite transponders, military radars, high-power radio, and UHF television transmitters.
There are two configurations for both the solid-state and tube amps. The first is a combo guitar amplifier kit, which includes an amplifier and a speaker in one unit. This is often the most portable option and includes one to four speakers.
The other option is a stack configuration; this is where the head, or amp, is separate from the cab, or speaker. The amp rests on top of the speaker and powers the unit. A half-stack refers to a setup with one speaker cab. A full stack refers to a setup with two speaker cabinets. PA systems can also work as guitar amplification kits. Though not recommended for amplifying electric guitars, they work well to amplify acoustic guitars direct or via microphone.
Outside of these traditional guitar amplifier kits, there are also custom alternatives for making portable amplification devices. Many gear lovers enjoy making their own mini guitar amplifier kits or portable amplification systems for electric guitars. Portable amps that clip on the belt can be constructed with a nine-volt battery to give the guitar a boost of sound. While these devices are insignificant for performances, some musicians use them for practice or recording.
