modeling amplifiers , the amplifiers market segment best-selling or most popular technology used for solid-state amplified sounds ; feel as traditional tube amplifiers offer many advantages for almost any application.

There are also hybrids , which have generated output transistors and a tube preamplifier that produces a basic tone .
3. digital modeling

It is possible to obtain maximum sound quality of a tube amp without having to be in the old school. digital modeling amplifiers simulate the sound through software, so you can get the sound from a variety of amplifiers at once. They also come with built-in digital effects such as tremolo , chorus , etc. . and a foot switch that lets you switch between tones .
4. Manufacture

The material which is made the amplifier can affect the quality of their sound. Because a thinner material may cause the speaker to vibrate and become loose , we recommend a thickness of at least 1 / 2 ” .

An amplifier with a closed back bass produce a better quality of a speaker.

In others, you have the ability to adjust the frequency, giving it control . Most preamps have three knobs on , some have five and some have even more.
8. Controls

Search the tone controls , those that include EQ Low, medium , high , presence , gain and resonance. And make sure the controls are a useful function and which are not only for the eyes.
9. Sound

Different amps have different sounds , so try an amplifier is essential to get the sound you want. It is also important to consider the genre that will probably touch. Does musical tastes , or planning to play softer rock? Often, some brands can adapt to a style rather than to others.
