If you're interested in learning to play guitar, not only are you going to want the right guitar, if you want to play the electric guitar or even an acoustic guitar in some cases, your choice of guitar amplifier is probably going to be as important. There are several different types of amps that a guitarist can choose from. Here's a brief rundown of the different types of amps that are available to you.
The first option is known as a solid state amplifier. These amplifiers are generally cleaner in sound than other amps, they run at a much lower power ratings, are lighter and are typically the cheaper amplifier option. The only issues you'll find with a solid state amp is that the sound you get is pretty generic. You can't do much to shape the sound like you would with other amps. However, there are still quality amplifier manufactures that produce good quality solid state amps.
The other option is a valve state or tube amp. These amps are typically what every guitar player wants. These amps allow for bigger and warmer tone. Since the sound moves through several valve tubes, you can shape your tone in ways you never thought possible. The downside is these amps are heavier, more temperamental, and much more expensive. However, if it's an original sound you want, this is really the only amp you'll want.
The next option is the configuration of your amp. You may want to go with an amp head and a separate speaker cabinet enclosure. If you still want the control of a separate head and speaker, known as a stack, you can choose a controller and speaker in one unit known as a combo amp. These are smaller and less powerful, but they still provide the same quality as you will get in a half or full stack.
What type of amplifier you choose will have a great deal to do with your sound preference and your budget. Fortunately, there are many quality amplifier brands that make different amps for different sounds. Simply test out a few that fit into your budget and pick the one that best suits your needs and desires.
