ENGL E633 Fireball 25 Head


Add to Cart
This amp is as hot as a Fireball. The Clean channel offers chimey, shimmering cleans and starts to smoothly break up as you edge past 12 o’clock on the gain knob. At higher gain settings, you can wring chimey, shimmering crunch sounds out of this channel. The Lead channel starts where the Clean channel ends, offering up endless amounts of gain. This channel is perfect for any style of rock and metal music. The built-in Noise Gate helps you tame any extraneous noise at higher gain settings.

The Mid Boost function is a great option for cutting through any band mix, for example when you need to take center stage for a solo! The power amp is equipped with 6L6GC tubes, just like the amp’s bigger brother, the Fireball 100. Thanks to the power amp design, the Fireball 25 has enough punch and headroom for every live and studio situation. The built-in Power Soak offers you the opportunity to play late at night or whenever higher volumes are unacceptable, and also gives you the chance to push the power amp to break up at lower volumes.
