A good quality amplifier can make a huge difference

 But one item is an absolute necessity: no electric guitar can be performed or make any decent sound without an amplifier. A good quality amplifier can make a huge difference, and if you are looking to buy an electric guitar, or perhaps move on from a basic starter model, then a good quality and flexible amplifier unit to match the guitar will make all the difference. After all, it is the guitar which produces the signal, but the amplifier which makes the sound. It would be the same as considering a choir and the conductor. Both are important, but no matter how good the conductor, it is the choir which ultimately make the sound, and have the greatest impact on the eventual quality of sound heard.
Amplifiers that were created specifically for an instrument were first developed as part of the electric guitar development, and it was these instruments which first benefited from any kind of external amplification. These early units were developed in the 1930s, and it was the advent of more advanced electrics that enabled amplification units to be built that were both economic and of good quality. Of course, the amplification of guitars had been around for much longer, but simply for acoustic guitars, with microphones set up. The combination of electronic amplification units coupled to electric guitars gave rise to a whole new sound of music, originally popularised by the steel stung sound of the Hawaiian guitar.
The first factor to consider, when shopping for such a device, is its sound field. You have to ensure that the amplifier will be able to "fill" the room with sound. Experts recommend 5.1 system models for traditional living rooms or ones with standard measurements designed for home theatres. If you have a larger room, you might want to opt for a 7.1 system model.
It is perfectly natural for you to want your home theatre amplifier to be as powerful as possible. In order to make this dream come true, you should look for a device that has over 80 watts average power per channel (W/Ch). In general, expert say that this is a good power for an average home theatre set in a traditional living room.
When considering the watt average power per channel, you should be careful not to confuse it with the peak power that the device can produce. Peak power refers to the power derived from the device's voltage, during a loud high point. In general, this is not an officially recognized measure for the power of amplifiers, as it depends a lot on the type of signal produced by the home theatre. For this reason, it is best not to rely on this measure, when buying a product.
