The Fireball 100 (E635) is ENGL’s straightforward two-channel, 100-watt metal head. The Clean channel pushes into crunch past noon and the Lead channel carries the real gain, each with its own gain control over a shared three-band EQ, plus Bright, Bottom and a footswitchable Mid Boost. Four 6L6GCs, a noise gate, a tube-buffered loop and two master volumes round it out.
