ENGL Fireball 25 Blackout E633BO-KT77 (Black) 25 Watt Tube Guitar A...
The ENGL Fireball 25 Blackout E633BO-KT77 brings the focused Fireball voice into an all-black amplifier head built for players who want tight response and articulate high-gain detail. Its 25-watt all-tube design combines 4 ECC83 preamp tubes with 2 KT77 power amp tubes for a compact guitar amplifier built around direct control and a strong, defined sound.
Two Channels with Focused Tone Shaping
Clean and Lead channels give you separate gain control for each side of the amp. Bass, Middle, and Treble controls shape the core response, while Lead Volume, Presence, and Master controls help balance drive, upper frequency detail, and overall output. Mid Boost adds another sound-shaping option when you want more midrange emphasis.
Power Control for Different Playing Environments
The rear panel Power Soak offers Full Power, Mid Power, Low Power, and Speaker Off settings. This lets you change the amplifier output behavior without giving up access to the Fireball control layout. A rear Noise Gate threshold control helps manage unwanted noise when using higher gain settings, while the integrated noise gate keeps the feature close to the amp rather than requiring another device in the signal path.
Flexible Connections for a Working Guitar Rig
A tube-buffered serial FX Loop supports external effects, and a dual footswitch jack supports the ENGL Z4 for remote control functions. Speaker connections support 1 x 8 to 16 ohms or 2 x 16 ohms, while a line output adds another routing option. The chassis is 42 centimeters wide, weighs 11 kilograms, and is handcrafted in Germany for a focused combination of Fireball tone, practical control, and the Blackout Series appearance.
