Get the facts on guitar amps with answers to ten FAQs from the experts at Premier Guitar.
What is a guitar amplifier?
An amplifier is to your electric guitar as a blast of electricity was to Frankenstein’s monster: it gives it life. In simple and traditional terms, it receives the signal created by your electric guitar’s pickups, processes and boosts that signal, and amplifies it through one or multiple speakers.
What’s the difference between an amp head and a combo amplifier?
An amp basically involves two sections. The first comprises a chassis, control panel, and circuit that process the signal, while the second comprises a speaker section which is connected to the circuit. Sometimes they’re both housed together in one box called a combo amp. Sometimes the first part is housed on its own, and can be connected to a separate speaker cabinet. That is an amp head.
What types of amps are there?
There are four main types of amps: tube (or valve, as the Brits call ’em), solid-state, hybrid (both tube and solid-state), and modeling.
What’s the most popular type of amp?
The tube amp. From the 1950s onward, tube amplifiers have dominated stages around the world, but solid-state amplifiers emerged in the 1960s as an alternative to the perceived unreliability of tube circuits. These days, loads of touring and studio guitarists are opting for modeling amps and even amp pedals.
What’s a tube amp?
Tube amplifiers are named after the glass vacuum tubes that form a key part of the amp’s circuitry. The signal is usually passed through two sections of tubes—preamp and power amp—which impart different characteristics to the resulting sound depending on how an amp’s controls are set. A lot of players describe the tube sound with words like warmth, sag, punch, and chewiness. You can check out our in-depth guide on tube amps for more info.
What’s a solid state amp?
Solid-state amps are those that don’t use any tubes at all, and instead use transistors to affect and amplify your guitar’s signal. Here’s an explainer on solid-state amp tech.
What’s a modeling or digital amp?
These are entirely digital modules that mimic or ‘model’ the function of amplifiers. They can be paired with real speaker cabinets, or with digital impulse response (IR) programs, which in turn mimic what a speaker cabinet does in various rooms. Given their size and ease of use, more touring guitarists are choosing them
What are 1x12s, 2x12s, and 4x12s?
These are shorthand terms for speaker cabinets that hook up to an amplifier. The 12 refers to the size of the speaker cone: 12 inches. The preceding number refers to the number of speakers in the cabinet. A 1x12 has one 12-inch speaker, a 2x12 has two 12-inch speakers, and so on. These are also sometimes designated as 112, 212, and 412 by manufacturers.
What type of amp is best?
You’re not gonna like this answer, but it’s the one that’s right for you. Whatever sounds best to your ears is the best amplifier for you. Don’t worry what the forum overlords and trendsetters are doing. They’re not listening to your playing, you are, so your own satisfaction comes first. Consider various factors: How often will you play through the amp? How loud or quiet do you need it to go? How big or small do you want it to be? What style of music are you playing? What’s your budget? Add ’em up, do your research, and pick what fits your style.

Metallica's M72 World Tour will be extended into a third year with 21 North American shows spanning April, May, and June 2025.
The M72 World Tour’s 2025 itinerary will continue the hallowed No Repeat Weekend tradition, with each night of the two-show stands featuring entirely different setlists and support lineups. These will include the band’s first Nashville shows in five years on May 1 and 3 at Nissan Stadium, as well as Metallica’s return to Tampa after 15 years on June 6 and 8 at Raymond James Stadium. M72 has also confirmed its much anticipated Bay Area hometown play, to take place June 20 and 22 with the band’s debut performances at Levi's Stadium in Santa Clara.
In a new twist, M72 2025 will feature several single shows bringing the tour’s full production, with its massive in-the-round stage, to venues including two college football stadiums: JMA Wireless Dome in Syracuse, New York on April 19, and Metallica's first ever visit to Blacksburg, Virginia, home of the Virginia Tech Hokies. The May 7 show at Lane Stadium will mark the culmination of 20+ years of “Enter Sandman” playing as the Hokies take the field.
In addition to playing football stadiums across the nation, the M72 World Tour’s 2025 itinerary will also include two festival headlines—the first being the opening night of the run April 12 at Sick New World at the Las Vegas Festival Grounds. May 9 and 11 will then mark a festival/No Repeat Weekend combo as Metallica plays two headline sets at Sonic Temple at Historic Crew Stadium in Columbus, Ohio.
