Operator´s Manual
Please, first read this manual carefully!
Screamer 50 - 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 first 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 amplifier apart. The Screamer comes complete with a bit of technical wizardry which you'll find 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. You also get two different connection systems for different footswitches-conventional ¼" jacks as well as a port for the ENGL compact footswitch Z-5 (optional). And then there's the ingenious feature "V.L.S.", an adapted version of the extremely popular and highly practical Master A/B switching circuit found on high-end ENGL heads.
Quality components, excellent workmanship and strict quality control ensure this amp retains its value. You'll find guidelines on care and maintenance of tube amps on the last page of the manual. Please read and heed these before operating your amp. You'll also come across boxes shaded grey throughout the manual. These are located between the descriptions of the amp's functions and contain handy tips on the preceding function. All critical information pertaining to the operation of this amp is preceded by "NOTE" or "CAUTION." Please pay particular attention to these safety tips. The ENGL team wishes you all the best—may you and your amp enjoy a "harmonically rich" future together!

1 Input: Input¼" unbalanced input. Plug your guitar cord in here.
2 Clean: Input sensitivity control (Gain) for the Clean and the Crunch channels.
(Clean: set the Gain-button 11 to the Lo position, Crunch: set the Gain-button 11 to the Hi position).
A TIP from the Designer: Gain settings depend on what type of pickups are installed in your guitar. The recommended setting for humbuckers or active pickups lies between the 10 and 1 o’clock positions and 12 to 3 o’clock for single coils for a pure clean response; the Gain button must be in the OFF-position.
3 Bright: Alters the EQ by boosting the upper treble range; effectiveness decreases at higher Gain (2,4) settings; the Bright feature affects all channels.
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 Lead: Gain control pot for the Soft Lead channel and the Heavy Lead channel. It controls the amount of preamp overdrive in the Lead mode. (Soft Lead: set the Gain-button 11 to the Lo position, Heavy Lead: set the Gain-button to the Hi position).
CAUTION: Extremely high gain and volume levels in the Lead mode can produce
strong feedback. Avoid feedback squeals, they lead to hearing loss and damaged speakers!
A TIP from the Designer: To get Crunch-sounds and Rhythm-sounds set this control between
the 9 and 12 o´clock´s position (depending on the type of pick-up) and leave the Gain 11 pusbutton in the Off-position.
5 Bass: Bottom end voicing control of the preamps´s passive EQ. 6 Middle: Mid-range voicing control of the preamp´s passive EQ. 7 Treble: Upper range voicing control of the preamp´s passive EQ.
A TIP from the Designer: To get an idea of this amp's capabilities, I suggest you set the tone control pots Bass (5), Middle (6), Treble (7) and Lead Presence (8) to the 12 o'clock position. For extremely soft lead, blues or jazz sounds, try setting the Treble knob to somewhere in the 8-to-11 o'clock range. For aggressive metal riffs or spanky funk sounds, go for something in the range of 11 to 3 o'clock.
8 Lead Presence: This control defines the Treble response in the poweramp stage for the Lead channel.
A TIP from the Designer: When you've adjusted the amp to relatively loud levels and high Gain settings reduce the amount of Lead Presence (8) and Treble (7) to prevent annoying feedback that is generated when your guitar's pickups and the speaker interact—something in the 8-to-12 o'clock range should do just fine.
9 Reverb: Reverb control, adjusts the portion of the reverb signal and increases reverb intensity
if you rotate it clockwise; the reverb can be switched on/off via the respective footswitch connected to jack 19 or 21.
