Operator´s Manual

Please, first read this manual carefully!

The Fireball is dual channel, all-tube head that sets new standards for rock amps.
Boasting a totally new design, the head is equipped with a 6L6-loaded power amp (60 watts)
that packs a mighty punch and cranks out both cutting-edge hi-gain lead sounds and crisp
clean tone. Its vast gain reserves make the FIREBALL the king of the hill, the no. 1 rock amp
in the business. Delivering tight bottom end, smooth top end, and incredible sound pressure
levels, this amp puts into the hands of today's guitarists the sonic tools they need to carve
out highly defined, expressive tones of their own. Other trademark ENGL features include a
second master volume, electronic power amp monitoring, and a variable FX loop.
The team is convinced that this amp will delight and inspire you.
FIREBALL - an amp that will rock your world!

2 Gain

This knob determines input sensitivity, in other words, the input level of the preamp. In Normal Gain
mode, it dials in the basic volume level and determines the amount of preamp saturation.

A tip from the designer:

The amount of distortion depends on the type of pickups your guitar is equipped with. Pickups with very
high output levels will overdrive the preamp when the knob is set to about the 12 o'clock position in
Normal Gain mode. This means that settings in the 12 to 5 o'clock range add varying levels of grit to the
signal, eliciting crunch sounds. When you have dialed in higher gain settings, you can clean up the sound
by simply backing off the volume knob of your guitar.
The amp's remarkably sensitive response to varying input levels lets you dial in a wast range of gain
levels in both Normal and Ultra Gain modes simply by working the guitar's volume knob.

CAUTION: Extremely high gain and volume levels in Ultra Gain mode can produce strong feedback.
Avoid feedback squeals, they lead to hearing loss and damaged speakers! Reduce the Gain, Treble
and Presence levels at higher volumes in order to avoid uncontrolled feedback!

3 Bright

Alters the EQ by boosting the upper treble range; effectiveness decreases at higher Gain settings;
the Bright feature affects both modes.

A tip from the designer:

For a crisp glassy tone, set the Bright switch to the On position.
This setting boosts the treble response of muddy pickups.

4 Depth

Alters the EQ by boosting the low end range; the Depth feature affects both Gain modes.

A tip from the designer:

When you're using a guitar equipped with bass-heavy pickups, you are well-advised to switch
this feature off to prevent it from muddying your tone, particularly at higher Gain settings.
