Manufacturers

Blackstar Amplification is a British amp maker founded by a team of ex-Marshall engineers, known for its proprietary ISF (Infinite Shape Feature) voicing control and for rapidly becoming one of the UK's most successful modern amplifier brands.

Fender's tube amplifiers are as foundational to American music as its guitars. From the tweed-covered combos of the 1950s to the blackface classics of the '60s, Fender amps defined the clean, chiming sound at the heart of rock, country, blues, and surf music.

Kemper is the German maker of the Profiler, a digital amplifier built around 'profiling' technology that captures the complete sonic and dynamic behavior of a real amplifier rather than modeling it from a static circuit description.

Marshall Amplification is the defining sound of British rock guitar amplification. Founded by Jim Marshall, the company's tube amps and stacks — from the original Plexi to the JCM800 — have powered everything from blues-rock to heavy metal for over sixty years.

Mesa/Boogie is an American boutique amp maker known for pioneering cascading-gain preamp design, letting a single amp move smoothly from clean to heavily saturated tones. Its Mark and Rectifier series have shaped the sound of everything from Santana's fusion-rock to Metallica's thrash metal.

Orange Amplification is the independent British amp maker known for its thick, creamy tube tone and distinctive orange-covered cabinets, embraced everywhere from 1970s blues-rock to modern stoner, doom, and metal.

Positive Grid is the maker of the Spark line of smart practice amps, which pair digital amp modeling with an app-driven experience — auto chord detection, backing-track jamming, and a searchable tone-matching library — aimed at practicing and songwriting rather than live gigging.

Randall Amplifiers is an American amp maker best known for its high-gain solid-state and hybrid heads, which became the backline of choice for thrash and heavy metal guitarists from the 1980s onward — most famously Pantera's Dimebag Darrell.

Two-Rock is an American boutique amplifier maker known for hand-wired, high-headroom tube amps prized as a clean, dynamic platform for pedals — closely associated with Joe Bonamassa's signature amps.

Vox is the British amp maker behind the AC30 — the chiming, jangly tone at the heart of The Beatles, The Shadows, and generations of British Invasion and indie guitarists.
