Engl E633BO Fireball 25 Blackout

The essential facts about the ENGL Fireball 25 Blackout E633BO amp head A compact 25 W all-tube head equipped with two 6L6 power tubes for a massive, precise high-gain sound. Two Clean and Lead channels with independent gain controls let you move from a bright clean tone to extremely dense metal distortion. Built-in Power Soak with full-power, 5 W, 1 W and loudspeaker defeat settings: ideal for making the most of the character of the tubes at controlled volume. Complete Blackout finishing and a protective metal grille deliver a dark, rugged look that is unmistakably built for the stage. The Fireball 25 in its Blackout version: the ENGL high-gain icon gets darker The Fireball is one of the historic highlights of the ENGL catalogue for guitarists seeking high gain, tight low end and an ultra-precise response. With the Fireball 25 Blackout E633BO, the German brand brings this aggressive character to a compact 25 W head, dressed in a particularly successful all-black finishing. This Blackout version retains the direct approach that has made the Fireball series so renowned: no unnecessary frills, effective controls and an instantly recognisable sound. Its portable format makes it a particularly compelling alternative to large, high-powered heads, without sacrificing the projection or sonic authority expected from an ENGL amp. A compact head for modern metal, rehearsals and the studio The ENGL Fireball 25 Blackout is primarily aimed at rock and metal guitarists looking for tight, articulate distortion that can be used in a wide range of settings. It is equally suited to the experienced musician looking for a reliable amp for rehearsals and the gigging guitarist wanting a compact head to pair with a 1x12, 2x12 or 4x12 cabinet. Thanks to its Power Soak attenuator, it also remains a relevant choice for home studios and home use. The 1 W setting preserves a lively response while keeping the volume down.
