Description
The Engl Fireball 25 is a compact powerhouse designed for guitarists who crave blistering metal tones without sacrificing clarity. This 25-watt tube amp head is the little sibling of the renowned Fireball 100, packing a punch with its two-channel setup. The Lead channel unleashes a cascade of high-gain ferocity, while the Clean channel delivers shimmering cleans that can evolve into a smooth crunch as you dial up the gain. Both channels are complemented by a built-in noise gate, ensuring your sound remains tight and focused even at the highest gain settings.
The Fireball 25's preamp section is loaded with four 12AX7 tubes, while the power amp features two robust 6L6GC tubes, offering a rich and articulate tube crunch. Tone shaping is straightforward yet versatile, thanks to a 3-band EQ, Mid Boost switch, and a Presence control. Whether you're performing on stage or practicing at home, the built-in power soak allows you to enjoy cranked-up tones at manageable volumes. Additionally, the buffered FX loop maintains your effects' integrity, making this amp a reliable choice for both live performances and studio sessions.

- 25-watt high-gain tube amp head with Clean and Lead channels
