A FEW WORDS FROM THE AMP DESIGNER
„Back in the mid of the nineties I designed the very rst Screamer amp and since then this very popular
amp obtained a several smaller updates including sound tuning and additional features.
Within this brand new fantastic combo amplier, the Screamer 50 Mark II, I have packed some clever
and useful ideas that offers you a broader spectrum of tonal palettes like the “Mid Boost Plusex” switch
matrix. And last but not least I spent many hours in some further sound tuning sessions, my favourite
labour that is at ENGL Amps.
I hope you will enjoy the results of all my efforts.“

INTRODUCTION
The Screamer 50 Mark II delivers the sonic goods – tons of tone and palette of hip sounds from squeaky
clean to hi-gain shred and everything in between. This all-tube beast is your rst choice for many different
sound styles! With a host of practical features and a clearly-arranged control panel, handling this amp is
a piece of cake. The Screamer‘s opulent visuals are certainly arresting, but its unique, creamy tube tone
and silky spring reverb truly set this amplier apart. The Screamer comes complete with a bit of technical
wizardry which you‘ll nd useful where it counts most – out there in the real world of rehearsing and
gigging. Among these features are a Lo/Hi Gain switch, which in effect doubles your choice of channels
from two – Clean and Lead – to four – the afore-mentioned, plus Crunch and Heavy Lead. The built-in Noise
Gate helps stie the annoying hiss often generated when Gain Hi is engaged at very high gain levels. Other
trademark ENGL features include a second master volume (Master A/B), and an adjustable, switchable FX
loop (parallel/serial).
There are few more handy features to rave about: The Screamer amp sports our Serial Amp Control Port,
or S.A.C. Port for short. Plug an ENGL Z9 into it and get hip to some very convenient remote control options.
This footboard lets you activate the two channels directly in combination with Gain Lo/Hi and Master A/B
switching simply by tapping its four footswitches. And that affords you instant access to four sound varia-
tions at two different volume levels each. Moreover you can access further prominent features like Master
A/B, FX Loop off/on and Reverb off/on; the built-in Noise Gate is switchable via footswitch, too. In addition,
the amp comes with three stereo jacks designed to accept dual footswitches like the ENGL Z4 or a MIDI
switching system (e.g. ENGL Z11) for selecting the channels and other crucial Amp features.
Old world craftsmanship and highest quality components are part of what makes ENGL amps so special,
and the Screamer 50 Mark II is no exception. On that note, please read and heed the guidelines on handling
all-tube amps. The ENGL team is convinced that this amp will delight and inspire you.

Bright feature affects all channels.
Lead
Gain control for the Soft Lead and the Heavy Lead channel. This knob determines the preamp´s input sensitivity when the Soft Lead and the Heavy Lead channel is selected and, by extension, the preamp signal´s
saturation.
(Soft Lead: Gain Lo/Hi button disengaged; Heavy Lead: Gain Lo/Hi button engaged.)
CAUTION: Extremely high gain and volume levels in the Lead channels can produce powerful feedback. Avoid
feedback squeals, they lead to hearing loss and damaged speakers!
Bass

Treble
Upper range voicing control of the preamp´s passive EQ.
Lead Presence

This controls adjusts the portion of the reverb signal and increases reverb intensity if you rotate it clock-
wise; the reverb can be switched on/off via the respective footswitch.
Lead Volume
Volume control for the Lead channel (pre-FX Loop, inuences the send level). Use this knob to dial in the
desired balance of levels between the Lead and Clean channels.
Gain Lo/Hi
When you press this button, the input sensitivity of both channels is increased. The Hi-Gain function actually
turns Clean into a „Crunch“ channel, and Lead into a „Heavy Lead“ channel. It can also be activated via a
suitable footswitch; the Gain Lo/Hi button is automatically disabled when you connect a footswitch. The
yellow LED illuminates to indicate „Hi-Gain“ mode is active.
Clean/Lead
Channel selector push-button for Clean and Lead modes, red LED indicate Lead mode; This function can also
be activated via the respective footswitch connected. Once a footswitch is connected, the channel selector
push-button is deactivated.
Master A
Master A volume knob. Located post effect loop, it controls power amp output. The red LED to the right of
the knob lights up to indicate Master A is enabled and determining the master level.
You can switch between and using a ENGL Z9 connected to the S.A.C. Port or a footswitch connected to the
TRS footswitch inputs.
Master B
Master B volume knob. Located post effect loop, it controls power amp output. The green LED to the right of
the knob lights up to indicate Master B is enabled and determining the master level.
Stand By
Power amp standby switch: Use this switch to silence (0 position) the amp when you take longer break.
The amp‘s tubes stay nice and toasty, and the amp is ready to roll immediately when you ramp it back up
to full power. The standby switch is also well-suited for muting the amp for brief breaks, for instance when
you‘re switching guitars.
Power
Mains power on/off.
Please note: ensure that the Stand By switch is set to Stand By (0 position) before you switch the amp
on. Let the tubes heat up for about 30 seconds before you activate the power amp. This procedure spares
the tubes.
