Founded in 1983 by musician Edmund Engl and electronics designer Horst Langer, ENGL is a German amplifier manufacturer based in Tittmoning, Bavaria. The company debuted at Musikmesse Frankfurt in 1984 with what is widely regarded as the world's first programmable guitar amplifier — a concept born from Edmund Engl's frustration as a working musician who wanted multiple tones accessible via footswitch. All ENGL amplifiers are built in Germany, and the company has earned a reputation as one of Europe's premier tube amp builders, particularly favored by rock and metal guitarists.

ENGL's lineup spans amp heads, combos, speaker cabinets, and effects pedals. Landmark models include the Straight (1985), which introduced massive gain and features like Lead Boost and Mid Shift switching; the four-channel Savage (1993); the Powerball, which pioneered an integrated noise gate and tube protection circuit; and the Fireball, a compact high-gain head that has become one of the brand's most recognizable products. Other notable models include the Invader, Ironball, Screamer, and the Artist Edition and Special Edition series developed with endorsed players.

ENGL's artist roster reflects the brand's stronghold in hard rock and metal, with players including Ritchie Blackmore, Steve Morse (Deep Purple), Paul Stanley (KISS), Vivian Campbell (Def Leppard), Glenn Tipton and Richie Faulkner (Judas Priest), Marty Friedman, Gary Holt (Exodus), Scott Gorham (Thin Lizzy), and Mick Box (Uriah Heep).

Engl has 111 products cataloged on Equipboard, including Guitar Amplifier Heads, Guitar Amplifier Cabinets, and Combo Guitar Amplifiers. Their gear is featured by 175 artists, with the strongest followings in Rock, Metal, and Electronic. Notable users include Marty Friedman, Muhammed Suiçmez, and Jeff Loomis. Most Engl products sit firmly in the high-end, boutique range.
