Congratulations, ENGL Amp user! ENGL RaiderThe is one mean machine of a tube-
driven guitar amplifier, engineered to inspire you and enthuse your audience.
Alongside to-die-for tone, it puts at your fingertips everything you need to tap your
creative potential and make your musical message heard and felt!
When yours truly, a humble ENGL amp designer by profession, developed the ENGL
Raider 100 amp, two goals loomed large in my mind. I aimed to pair tonal perfection
with useful features that make sound (pun intended) sense in the real world. Out
came a newtype of design – a nifty combinationof two primary channels 1and 2, each
with different gain structures, and two gain stages. That adds up to four different
basic sounds ranging from clean to hi gain lead. Best of all, you can dial in just about
any flavor of crunch in between, quickly and easily.
To broaden the tonal palette and afford you even greater sound-sculpting flexibility, I
endowed the Raider's preamp section with a fresh, new Mid Boost button. Have fun
mixing and matching its two settings with any of the four gain stages.
With so many options to choose from on the fly, you enjoy instant access to
painstakingly tuned, tonally balanced sounds that will serve you well for many styles
and playing techniques. Lead sounds with a mighty midrange punch, lean-and-mean
rhythm guitar tones, or heavy-duty low end for power chord riffing – you'll find your
amp delivers all this and a lot more. And Channel 1 sports innovative brightness
boosting circuits designed to accentuate this channel's tonal nuances.
Here's how this works: One Bright button affects both of Channel 1's Lo and Hi Gain
stages, and another special Clean Bright button affects Channel 1's Lo Gain stage only.
Engage it to conjure sparkling clean sounds. On top of this, you get a button that lets
you determine if the two power amp voicing knobs and shape
the power amp's frequency response for Channel 1. The alternative is to have a
precision-tuned, hardwired EQ filtering circuit shape the power amp's response when
Channel 1 is active.
A/B Master switching is a powerful option that has proven its merits in countless ENGL
amps (it featured in E920 power amps since the late '80s and in the legendary
SAVAGE 120 head since '93!). Your Raider Combo also sports two effect loops and a
high quality spring reverb system to round out its arsenal of sound-shaping tools.
The tonal paletteranges from vintage clean to classic grind,and from creamy rock lead
tone with thick, lush tubeoverdrive to the kindof massive hi-gain lead sound
cut through in appropriate playing situations.
And there's more: This amp sports our Serial Amp Control Port, or S.A.C. Port for short.
Plug an ENGL Z-9 CustomFoot Controller into to it and get hip to some veryconvenient
remote control options. This footboard lets you activate the two channels in
combination with the Hi Gain option and Master A/B switching directly simply by
tapping its four footswitches. And that affords you instant access to four sound
variations at four different volume levels.
In addition, the amp comes with three stereo jacks designed to accept dual
footswitches like the ENGL Z-4 or a MIDI switching system (e.g. ENGL Z-11) for
selecting the channels and other crucial Amp features.
The certainly match the interior's impressive
appointments. This amp's elegant and stylish look is sure to turn heads wherever you
play.

Among the hallmarks of this fine amp are painstaking workmanship and finishing as
well as rigorously tested and carefully selected quality components. You'll find
guidelines on care and maintenance of tube amps on page 19. Under the heading Tips
from the designer, you'll come across practical tips on the aforementioned features
throughout the manual. All critical information concerning the operation of this amp
is preceded by "NOTE", "CAUTION", "Read and heed" or some other eye-catching
comment. We're calling your attention to these remarks for reasons of safety or other
compelling motives, so please give them due consideration.
Everyone at ENGL is confident that the
outstanding features Simply plugin, play and be inspired
and are sure to delight you:

A few words of wisdom from the designer:
Though this amplifier is relatively easy to handle and you're probably raring to give it a
go, I recommend that you read the owner's manual thoroughly before you power it
up. It is equipped with several safety features that require further explanation to
prevent malfunctions.

1 Input
¼" unbalanced input jack. Plug your guitar in here using a shielded cord.
A tip from the designer:
Depending on the type of cord and its shielding, you may occasionally encounter
interference from sources such as radio stations or powerful magnetic fields. When
this occurs, try connecting your guitar to the amp using different cords. What's more,
to minimize signal degradation due to high-frequency loss, use the shortest cords
feasible (as a rule, the shorter the cord, the less susceptible it is to high-frequency
attenuation).

2 Bright
This feature boosts the upper end of the high frequency range for both Channel 1's
gain stages, Lo and Hi Gain (or Clean and Crunch modes, if you prefer). Its intensity
decreases as gain settings increase.
A tip from the designer:
For a crisp or glassy tone, activate the Bright boost. It brightens the sound of
humbucking or muddy pickups. is a global function; that is, it affects both gain
stages. Use it to tweak the amp's tone to taste, activating it to boost top-end
frequencies for both gain stages or deactivating it to dampen high end response, for
example, for Channel1's Hi Gain ( ) stage. If you want to addeven more top-end
sparkle to the Lo Gain stage ( ), activate the Clean Bright-function (9), which
affects Channel 1's Lo Gain stage only.
3 Gain 1
Gain control for the
is active; use it to dial in the desired amount of preamp distortion.
A tip from the designer:
The amount of distortion depends on your guitar's pickups. In Lo Gain mode, singlecoil pickups may begin saturating the preamp when the knob is set to approximately
the two o'clock position. Pickups with very high output levels (humbuckers or active
pickups) will evoke mild overdrive at even lower settings. If you want squeaky clean
tone (a pure guitar tone without preamp distortion, that is), simply back off the Gain
control knob accordingly.
If your guitar sports single-coils and you want to add some grit to your tone and bite to
your riffs, set the knob somewhere between 10 and 2 o'clock and Hi Gain active in
Channel 1. Forhigher output pickups such as humbucking or active jobs, dial insettings
between 9 and 1 o'clock and activate Hi Gain. For an even bigger, beefier crunch tone,
try Crunch Gain settings well beyond the 2 o'clock position.
CAUTION:

higher-gain Crunch sounds, your best bet is to turn the Treble knob down to prevent
the pickups and speakers from generating feedback (a setting in the 10-to -1 o'clock
range is recommended). Bear in mind that you also have the Bright (2) and the Clean
Bright (9) button at your disposal for shaping the high frequency range.

The signal remains completely dry when the knob is set to the 7 o'clock position or if
Reverb is deactivated via a footswitch. You can switch the reverb unit on and off using
a Z-9 Custom Footswitch connected to the S.A.C. Port (34) or a footswitch connected
to jack (35). The reverb unit is always on if you do not plug a footswitch into the port
(34) or jack (35).

Channel 1's volume and dial in the desired balance of levels with Channel 2. Because
this volume control is located pre effects loop, it also determines the effects send level

on.

This feature boosts the upper end of the high frequency range in Channel 1, affecting
the Lo Gain stage only (Clean mode). The Gain knob setting has no influence on Clean

Animportantnote onthePowerTubeMonitor(P.T.M.)system:
The electronic power amp monitoring system constantly gauges the current flowing
through each power amp tube. If it rises to too high a level the system shuts down the
given tube.
This can occur when the amp is operated incorrectly (for example, if the impedance is
wrong due to an incorrect speaker load; see page 17 and 18 for permissible loads), at
extreme power spikes, or when a tube is defective.
Reset this electronic monitoring system by switching the standby switch off and on
again. When you press the standby switch to turn the amp on again, the system again
