ENGL E646 VS Limited Edition Plug-in
Physically modeled tube guitar amp, speaker simulation and FX rack.
FX Rack / Zoom view
Introduction
The ENGL E646 VS plug-in is the next level in guitar processing. It offers a faithful digital rec-
reation of the original tube amp circuit and adds several important tools to help guitarists in
multiple situations. In the studio, on stage or in the rehearsal room.
In the FX Rack view you can access a noise gate, a vintage delay, 64 world-class Recording
Chains and a power amp simulation including an on-board power soak.
All of these features can be used or bypassed individually. You can - for example - bypass
the Preamp of the plug-in and record your own original tube preamp using the plug-in’s
power amp simulation, recording chains and FX!
Just connect the uncompensated Preamp output to the line-in of your audio interface
and record super-authentic guitar tones. This is not your average amp sim.
The main applications for this plug-in are:
1. Recording DI guitars, then editing and processing them in
the DAW completely, using the internal amp simulation,
the recording chains and the FX Rack.
2. Recording hardware preamps through the power amp
simulation and Recording Chains.
3. Practicing at home with minimal latency (in Apollo´s Con-
sole, for example), via your studio speakers, a home stereo
system, headphones or a real guitar amp and cabinet.
4. Playing live via a real power amp and speaker setup.
5. Playing LIVE, plugged straight into a live Console and /
or an in-ear system.
6. Re-Amp less than perfect DI guitar tracks, previously
recorded with other guitar-amp simulations.

The Basics
You can use the amp section of this plug-in exactly like you would operate the real ENGL E646 VS tube amplifier.
Plug in your guitar (via your computer audio interface in this case), select a Channel, adjust Gain, Tone and Volume... and Rock’n’Roll !
The ENGL plug-ins were developed with the Apollo series interfaces in mind really. Of course the ENGL plug-ins will work with any UAD-2 device, but to experience the ultra-low la-
tency (desirable for playing in real-time) you need an Apollo interface.
A good producer’s trick is to use a REAL GUITAR AMP (a small combo, for example) for real-time monitoring in the control room during tracking while recording only the DI guitar
signal! Then use the ENGL guitar amp plug-in when you play back the recorded tracks together with the rest of your music. You will need to split the dry guitar signal so it can be
recorded in the computer and routed to the real guitar amplifier input at the same time.
To play and record dry DI guitar tracks with the lowest latency and the highest quality possible connect your guitar to the Hi-Z Input of the Apollo Interface or connect a quality DI
Box and Mic Preamp to a line input of your Apollo series interface.
The Insert Effects Switch in the Console Software:
If you insert the ENGL E646 VS plug-in in the Console software mixer (to use the plug-in with the shortest possible latency) you have to decide whether you want to record pro-
cessed guitar amp sounds (switch INSERT EFFECTS to REC) or whether you only want to record the dry DI guitar signal, while monitoring the processed amp sound during track-
ing, of course (switch INSERT EFFECTS to MON).
The advantage of only monitoring the processed sound is that you can alter the settings of your amp and FX completely during mixdown! If you find out later that less or more
Gain or Delay would sound better for your song you can still make that happen.
The advantage of recording pre-processed guitar tracks might be that you will need less plug-ins during mixdown, as your guitar tracks will be ready to be mixed. All you can do
then is EQ and compress the recorded guitar tracks, or add effects, just like you would with traditional guitar amp recordings. Once you know ‘your sound’ you may even save
some time by recording processed guitar tracks and using them without further tweaking or fiddling around... your band mates or your producer may even appreciate this. ;-)

The controls of the ENGL Amplifier section
CHANNEL SELECT 1-4(via up/down & left/right arrows or Channel Select switches)
The E646 VS amp has four channels. To switch between the upper row of channels
(1&2) and the lower row (3&4) you may use the arrows just like with the hardware
amp. Alternatively you can use the CHANNEL SELECT LEDs and access each chan-
nel directly.
GAINS 1-4 (adjustable per channel):
Dial in as much crunch and distortion as you like with the gain knobs. Each of the
channels has its own dedicated Gain control. Channel 1 is the ‘CLEAN’ channel,
Channel 2 is the ‘CRUNCH’ channel. Channels 3 & 4 are both ‘LEAD’ channels.
Tone Stack (BASS, MIDDLE, TREBLE, adjustable per channel):
Just like any guitar amp the ENGL amps have controls to make the guitar tones
sound more mellow or harsher, add or cut low end, and boost or cut mids. There
are definitely no rules when it comes to adjusting the Tone Stack controls. If it
sounds right it probably IS right... You may browse through our presets and listen to
a wide range of different settings, many of which are customized for commonly used
guitars like Teles, Strats or Paulas...
MIDDLE VOICED (channels 3 & 4 only):
The channels 3 & 4 offer two different mid controls. You may switch between the
two sound options and use them for riffs or solo sounds to your liking.
TREBLE x2 (channels 1 & 2 only):
The channels 1 & 2 offer a dedicated TREBLE control for each channel. This way you
can easily adjust the sound according to the guitar and / or pickup you use for clean
or crunchy sounds.
MASTER A & B
The original hardware E646 amp has two MASTER channels so you can play with
different overall volume. We have modeled both channels so you can automate
rhythm and lead volumes, for example. Switch between both channels by clicking
the little switch between the MASTER A & B knobs alternating.
PRESENCE
With the PRESENCE control you add or cut ultra-high frequencies. Make your
sound harsher or duller to your liking. The PRESENCE control affects all four chan-
nels of the amp. You may use the A/B/C/D setting switches in the toolbar to re-
call different settings on the fly.
DEPTH PUNCH
Add some serious low-end to your sound. Some of the Recording Chains contain
less bass and may be enhanced in the low end by cranking up the DEPTH PUNCH
more than with other Recording Chains. The DEPTH PUNCH control affects all four
channels of the E646 because it sits in the power amp. You may use the
A/B/C/D setting switches in the toolbar to recall different settings on the fly.
STANDBY and POWER
You may bypass all processing of the plug-in with these two switches. Contrary to
the real amp in the plug-in these two switches are linked. No need to warm up
tubes in the plug-in or protect speaker cabinets.
If you only want to bypass the Amp section of the plug-in (to record your own hard-
ware tube preamp, for example) please use the FX Rack / Zoom view. You will find
the needed controls in the Power Soak section. Details below.

1. NOISE GATE
‘CLOSED’ LED
When lit this LED indicates that the Noise Gate is CLOSED. This means the
THRESHOLD setting is higher than the incoming guitar signal and the noise gate
dims the output signal of the amplifier by the amount adjusted with the RANGE con-
trol (e.g. 15dB in the picture above).
NOISE GATE ON / OFF:
Enable or disable the Noise Gate completely. Switch up (‘on’) means the Noise Gate
is activated.
THRESHOLD:
The Noise Gate will dim the output signal of the amplifier as soon as the input signal
(your guitar signal) falls below a certain level. This level is called Threshold. Adjust
the Threshold so the noise of the overdriven amp will be reduced, but make sure you
don´t cut fading notes or chords.
RANGE:
The output level of your amplifier will be reduced or muted when the input signal is
lower than the Threshold setting. You may dim the output level only by a few decibels
(dB), or completely mute the output in pauses by setting the RANGE to its maximum.
2. AMP FILTERS (switchable pre / post)
TIGHT Filter:
With the TIGHT filter you can cut LOW frequencies of either the DI guitar signal
(PRE) or the processed amp output (POST).
PRE: If your guitar pickups produce a rumbling bass sound you can filter the low
end before the DI sound even hits the amplifier.
POST: If you want to cut some of the low end of your amplifier setting (maybe even
only temporary) you can use this studio quality high pass filter to reduce the bass.
OFF: when set to OFF the TIGHT filter is in bypass mode.
SMOOTH Filter
With the SMOOTH filter you can cut HIGH frequencies of either the DI guitar signal
(PRE) or the processed amp output (POST).
PRE: If your guitar pickups catch a lot of hiss or noise you can filter the high end be-
fore the DI sound even hits the amplifier.
POST: If you want to cut some of the high end of your amplifier setting (maybe even
only temporary) you can use this studio quality low pass filter to reduce treble.
OFF: when set to OFF the SMOOTH filter is in bypass mode.

3. RECORDING CHAINS (Speaker Selection)
REC CHAINS:
Simply select a speaker and a complete studio setup by browsing through the REC
CHAINS pull-down menu!
In the past two decades Brainworx owner Dirk Ulrich has produced and recorded
with members of DREAM THEATER, TOTO, MICHAEL JACKSON, and with many
more famous and infamous acts. The Brainworx Studio in Germany (www.brainworx-
studio.de) is equipped with one of only nine NEVE VXS 72 Consoles ever made, and it
also hosts some of the finest outboard EQs and mic pre-amps available.
Using this impressive setup Dirk has produced a huge variety of customized ‘Re-
cording Chains’ for the ENGL amplifiers, which you can apply to your plug-in amp set-
tings. Imagine a selection of 64 perfectly miked and EQ-ed guitar cabinets which you
can select and use instantly with a single mouse click!
Many amp simulations give you some captured impulses of a selection of cabinets
and microphones, then they leave it up to you to EQ and further process these in-
complete setups. Mixing different microphone setups, adjusting phase and EQ, and
so on. But this really is not an easy job, it takes years of experience to get it right.
Now all you have to do is select the Recording Chain which sounds best for your
amp channel and setting, adjust the Tone Stack and Gain and you´re good to go!
Recallable, reliable, flexible and fast.
And if for any reason you should not like any of the Recording Chains the plug-in of-
fers you may use the very last setting (labeled CABINET BYPASS) and use your own
miked cabinet. This setting will give you the sound of a tube guitar amp wired
straight into a Console, which also may be a nice effects sound.
+ / - Switches (Plus / Minus):
Browse through the REC CHAINS by either using the pull-down menu of the REC
CHAIN text box (see above) or just click through the settings using the + and - sym-
bols.
AUTO & BAR selection:
If you are trying to find the best sounding REC CHAIN for your actual song it can be
tiring having to play a few chords, then grabbing the mouse to select the next REC
CHAIN, playing a few notes again, grabbing the mouse again, etc.
Instead the ENGL amp plug-in offers you the AUTO mode:
Just select a pattern (1 Bar, 2 Bars or 4 Bars) and the plug-in will activate the
available REC CHAINS automation, following the actual tempo setting of your DAW.
You can now play uninterrupted and simply listen to the sound of the various REC
CHAINS as the plug-in switches through all of them every single bar, every two bars
or every four bars, depending on your setting.
As soon as you hear the speaker setup you like best just stop AUTO mode by click-
ing the AUTO button again and manually select the desired REC CHAIN. Afterwards
just fine-tweak the TONE STACK and GAIN and there you are.

4. LO-FI DELAY
We have modeled a vintage stomp box delay and modeled the typical sound of it.
Limited frequency bandwidth, fading high frequencies on repeats, etc. Then we add-
ed modern features like a mix control, DAW controlled bpm-based tempo sync, etc.
Of course you will use your favorite selection of external effects like Chorus, Flanger,
Reverb and even other Delays to achieve your signature guitar tone, but we feel that
a nice & easy delay comes in handy even if you only want to try out presets etc.
Testing a lead / solo sound without hearing at least a touch of delay wouldn´t sound
realistic for many players, so we added this one effect. Plus, we really like the sound
of this vintage delay lay lay lay la la l.....
DELAY on/off:
Activate or deactivate the delay and all of its parameters with this switch.
Switch up: Delay is activated.
Switch down: Delay is bypassed / off.
TAP:
You can adjust the delay time by clicking rhythmically on the TAP button with your
mouse. This way you can adjust the tempo of your delay to your guitar riffs even if
you don´t play with a DAW and bpm-based tempo or click track.
TIME:
Alternatively you may just dial in a delay time based on milliseconds using the TIME
knob. Maximum Delay Time: 1,000 ms.
X2 & /2 (adjusting the delay time):
You may switch the actual delay time to double speed by clicking the /2 button.
You may switch the actual delay time to half time by clicking the x2 button.
Both buttons can be pressed repeatedly as long as the maximum delay time of
1,000 ms is not exceeded.
HOST BPM:
This LED panel indicates the actual tempo (4/4th, based on bpm, beats-per-minute)
reported by the DAW host software
MIX:
Use the MIX control to blend in as much delay signal with the dry amplifier sound
as desired. For unobtrusive delays we recommend settings around 10%, heavier
effect sounds may require settings of 50% or more.
FEEDBACK:
The FEEDBACK controls the number of repeats. While a setting of 99% will result
in an almost infinite delay loop, a typical setting for a rock lead sound may be
around 25%.
LO-FI:
With the LO-FI knob you control the amount of internal distortion, the resampling
quality, etc. The higher you go the worse the quality gets from a pure technical
stand point... but the more interesting it may sound for many guitar sounds and
styles.

5. INPUT GAIN:
If you want to drive the input of the ENGL preamp harder or softer you may adjust
the input gain to your liking. Some single coil pickups from older or vintage guitars
may deliver low level output which can be compensated with the INPUT GAIN.
The opposite goes for a lot of heavy metal style humbuckers. If you have recorded
the DI signal too hot or if you are using other plug-ins before entering the ENGL amp
plug-in you may want to dim the input signal.
With most standard guitars you can and should leave the INPUT GAIN at 0 (zero)
though.
6. Internal POWER SOAK:
In the real world power soaks are being used to reduce the volume of a guitar pow-
er amp. This way you can crank up a (tube) guitar power amp to drive it until it
starts clipping, and still record at a volume which will protect your hearing and keep
the neighbors friendly.
A clipping tube power amp adds distortion and harmonics to the guitar amp signal
and is something most guitar players love. A fully cranked up tube guitar amp tamed
in volume with a power soak will sound different than the same amp with the master
volume turned down.
We have modeled the behavior of the ENGL tube power amp, so you may experi-
ment with different settings of the Master Volume of the amp and the internal
POWER SOAK. We recommend a setting of roughly -10dB for most scenarios.
7. PRE-AMP and POWER AMP Activation:
BYPASS PRE:
With the BYPASS PRE switch you can switch off the ENGL preamp completely,
which may be wanted if you record your own hardware (tube or solid state) guitar
preamp with the ENGL amp plug-in.
In this case you may still use the internal POWER AMP and speaker / REC CHAINS
simulation and will be able to achieve amazing results recording your guitar sounds
without using an external power amp and speaker.
Switch up: Preamp is bypassed (off), Switch down: Preamp is active (on).
BYPASS POWER AMP:
If you want to use only the distortion of the ENGL preamp you may switch the pow-
er amp simulation off. This may sound cool if you use the ENGL plug-in to distort
other signals than a guitar. For a realistic guitar recording we recommend leaving
the power amp on, as it is an integral part of the overall sound of the amp.

8. SETTINGS / Top Toolbar:
UNDO / REDO:
You can undo and redo changes you made to the controls of the ENGL plug-in at any
time. The undo / redo will work for as many as 32 steps. This makes experimenting
and tweaking knobs easy. If you don´t like what you did... just undo it.
SETTINGS (A/B/C/D):
The ENGL amp plug-in offers four internal settings (A/B/C/D) which will be stored
with every preset. So, one preset can contain up to four amp and effects settings.
You may use similar amp settings with more or less delay, different delay times, etc.,
to quickly switch between different sounds, or you can switch from clean to crunch
to lead within one setup / preset.
The settings can be automated (!) in most DAW hosts. This way it´s possible to
switch from a dry rhythm sound to a lead sound with tons of delay, for example.
COPY / PASTE:
To set up variations of similar sounds you don´t have to dial in all the parameters
several times. Let´s say you like your setting A and want to use the same sound,
just without delay, as SETTING B.
-Simply press COPY while you are in SETTING A.
-Switch to SETTING B by pressing ‘B’ in the SETTINGS section.
-Press PASTE, now SETTING B is identical to SETTING A.
-Bypass the DELAY. Done.
Now you can switch between A & B and play the same sound with or without delay.
FX Rack:
Toggle between standard and zoom view.
FACTORY PRESETS
We have made a lot of presets for the ENGL amp plug-in, many of them have been
made to work perfectly with classic guitars like Strats, Teles or Paulas. All of the
factory presets offer A/B/C/D variations, do try them out!
This effectively quadruples the factory sounds you can browse through, and many
similar amp settings sound quite different with different FILTER or DELAY settings.
These presets are only intended to give you an easy start and to demo some of the
tones you can get out of the ENGL amp plug-in.
CREATING YOUR OWN SOUNDS & PRESETS
When you start to create your own sounds the most important elements to adjust
are the TONE STACK and the REC CHAINS.
-Select the amp channel you wish to play (clean or lead, for example)
-Set all the controls of the TONE STACK (Bass, Mids, Treble) to the center posi-
tion (’12-o-clock’).
-Dial in as much GAIN or Distortion as you like.
-Play through as many REC CHAINS as you like and pick the one that sounds
closest to what you are looking for without altering the TONE STACK.
-NOW start tweaking the TONE STACK to fine tune your amp settings.
-Add Delay or activate filters, the noise gate, etc.
Experiment, be creative. We are confident that the different channels of the amp
and the huge selection of REC CHAINS will offer you many possible combinations
that will sound great on a big variety of musical styles and genres.
Combine the ENGL amps with other UAD-2 plug-ins (dynamics, effects, room simu-
lation), and you will be able to create countless world-class production-ready guitar
sounds in the box. Enjoy.
