The invention of the first guitar amp is attributed to Antonio Paris in 1794. This is the birth of the concept of what we know today as the amplifier. A guitar amp is a special electronic device or machine that amplifies the low, mid, and high tones of a guitar or bass guitar so they can make sound via one or many loudspeakers, which are usually housed in an aluminum enclosure.
There are three types of guitar amplifiers to choose from, including solid-state (SS) designs, tube, and power amp units. Which one you use will depend on the type of guitar playing you're planning to accomplish. For instance, SS designs are recommended for the best beginner guitar amps because they are easier to operate and maintain than their tubes counterparts. On the other hand, tubes are the best choice for getting higher wattage output, but they tend to produce annoying feedback that makes it hard to achieve great guitar playing without excessive noise. As for poweramp units, these are usually recommended for professional guitar players who need extra power and volume from their equipment.
A 12ax7 guitar amp will usually consist of several components, including the pickup, the speaker, and the preamp. Pickups are used to locate the tones that are desired from the amplifier. The tone control functions can be set to enhance or dampen the sounds of the instrument. Most guitar amps have a volume control knob so that the tonal range of the sound can be adjusted individually.
A common design in modern day tube amps is the PA system, or "PA." The PA system is basically a built-in modular guitar amp that is often mounted on the floor. Tube amps are also sometimes called "stompboxes" because they function by serving as the basis for a "stomping music stand," which is commonly seen in churches and other worship centers. Although most guitarists prefer using solid state or "tube" guitar amps, there are some famous guitarists who still prefer to use the old-fashioned pa system, which was a solid state unit that included a cabinet that contained a speaker and a foot pedal.

Guitarists who are used to playing with a band can very well get along with the volume and clanging of each speaker. But if one guitarist is listening to a totally different sound than the rest, it will create an illusion that makes it seem like the band is practicing in a different place. This is why there are guitar amp simulation pedals, which will simulate different amp voices based on what the guitar player currently has set. The simulation gives the user a great way of mixing and matching different sounds and voices to produce a specific guitar tone that one may want.
If one wants to experiment with different speaker combinations and cabinet styles, they can purchase separate cabinet knobs that allow them to alter the tone of each speaker independently. Some guitar amps have onboard speakers that allow the user to change the balance of the bass and treble. This allows a variety of combination's that can be changed to achieve a particular sound. It is important, however, to make sure that the cabinet is not designed for amplification because it may not have enough wattage to handle all the amp voices.
