Amplifier Class XD

The Amplifier Class XD has a British patent owned by Cambridge Audio. The term XD comes from Crossover Displacement, which means this amplifier is based on a Crossover Displacement Technology. This technology removes a certain amount of distortion without collateral compromises. It first appeared, many years ago, in the Azur 840A integrated amp, and has…

Vacuum Tubes Amplifiers (Guitar)

Vacuum tube amplifiers (or valve amplifiers) are a type of electronic amplifier that uses vacuum tubes to increase the  amplitude or power of a signal. Before the solid-state semiconductors appeared, vacuum tubes were fairly common. At that time, the latter conquered the active electronic components in most instrument amplifier applications. Solid-state semiconductors, also known as transistor amps, took over since they are more affordable,…

Solid-State Guitar Amplifiers

Solid-state guitar amplifiers are based on a semiconductor or on a transistor. They are lighter, tougher, cheaper, and more reliable than the tube-based versions. In addition, they have many versions that vary in output power, size, price, and sound quality. This type of amps also vary in terms of functionality. Solid-State Guitar Amplifiers: Main Features…

Combo Guitar Amplifiers

Combo guitar amplifiers are merge all of the components of an amplification chain. These amps are a type of stack amplifier, which means their design is portable. There are many sizes, configurations, and output levels to choose from. Plus, everyone can use them, no matter if it’s the begging of their career or there are…

Hybrid Amplifiers for Guitar

Hybrid amplifiers are formed by a combination of tube and solid-state amplification. Most likely they will contain a tube power amplifier that is fed by a solid-state preamplifier circuit. In other cases, the tube preamplifier will be fed by a solid-state output stage. On the one hand, most original MusicMan amplifiers are categorized under the…

Modeling Amplifiers for Guitar

Each amplifier serves a specific purpose—and modeling amplifiers for guitar are not the exception. Modeling amplifiers mimic the sound of modern and vintage amplification gear, although physically they might look like conventional guitar amplifiers. As you might expect, the settings are different for each one. The modeling amplifier for guitar, in particular, offers diverse sounds…

Acoustic Guitar Amplifiers

Acoustic guitar amplifiers are similar to keyboard amplifiers because they tend to have a flat frequency and minimum correlation. The latter serve many purposes and diverse music genres; the most common being blues, folk, and bluegrass. This kind of amplifiers produce a clean sound that prevents unnecessary distortion. In order to obtain this clean sound,…

Amplifier Stack

An amplifier stack is a setup. There are half stacks, full-stacks, double-stalks, and plain old stalks. The term we use depends entirely on the music style we are aiming towards. So it’s not the same for retro heavy metal guitarists than for jazz guitarists. Specifically in regard to instrument amplifiers, there are two types. First,…
