The ENGL Fireball is a two-channel high-gain head delivering 60 or 100 watts of tightly voiced tube power through a quartet of EL34s. Its clean channel offers classic headroom while the lead channel provides dense, harmonically rich saturation with ENGL's hallmark note clarity under heavy distortion. The Fireball became a favorite among European metal and hard rock players for its combination of aggression and definition.
