{"product_id":"engl-e633bo-kt77-fireball-25-blackout-438981","title":"E633BO-KT77 Fireball 25 Blackout","description":"Everything you need to know about the ENGL Fireball 25 Blackout KT77 E633BO-KT77 25-watt all-tube amp head, powered by two KT77 power tubes for dense, tight and particularly incisive high gain. Two Clean and Lead channels with independent gain controls, capable of covering everything from bright clean tones to the most massive metal distortion. Built-in Power Soak with full-power, 5 W, 1 W and Speaker Off settings, allowing you to make the most of the amp’s character at controlled volume. Compact 11 kg format, Blackout finishing and metal grille with horizontal tubes: a head ready for both the stage and the studio. The Fireball in its Blackout version: a darker, more aggressive ENGL icon The Fireball series holds an essential place in the ENGL universe: that of tube amps designed for guitarists seeking modern, precise and tight distortion. With the Fireball 25 Blackout KT77 E633BO-KT77, the German brand brings this identity to a compact head with an entirely black look, enhanced by its horizontal protective grille. This version is not limited to a new aesthetic. Its power stage, equipped with two KT77 tubes, delivers a more responsive feel and a more aggressive attack, ideal for low-tuned riffs, highly defined rhythms and high-gain tones that need to remain clear in a dense mix. A compact high-gain head for the studio, rehearsals and the stage The ENGL Fireball 25 Blackout KT77 is aimed at intermediate to advanced guitarists who want the feel of a true tube amp without necessarily having to transport a 100-watt head. Its 25 watts already provide substantial volume headroom for rehearsing with a drummer, playing on stage or recording with a real guitar cabinet. It is particularly well suited to modern metal, heavy metal, hard rock, metalcore, thrash, death metal and hard-hitting rock. Thanks to its Clean channel and effi\n\n\u003ch2\u003eTechnical
