Three Tone Machines. Zero Prisoners.

Delivering powerful guitar tone has been ENGL Amplifiers’ singular mission for over two decades. Bold clean textures, snarling slabs of chunk, punishing rhythm sounds, and intense, singing sustain, are why ENGL tube amps grace the stages of some of the biggest names in hard rock and metal.

The ENGL Amplifier Bundle for UAD hardware and Apollo interfaces gives you three of ENGL’s most popular guitar amps as a jaw‑dropping plug-in bundle. Featuring the vintage-flavored E765 Retro Tube and the more modern‑sounding E646 VS Limited Edition and Savage 120 amps, this bundle also includes the super‑handy Brainworx bx_tuner plug‑in.

Re-amp your tracks through ENGL’s classic, vintage-flavored E765 Retro Tube and fire-breathing E646 VS Limited Edition and Savage 120 amps using your UAD DSP Accelerator

Track through ENGL amps in real time, with near-zero latency using your Apollo interface

Shape your guitar sounds further with built-in FX Rack and Recording Chains

Enjoy quick, precise guitar tuning with the included bx_tuner plug‑in

Included Plug-Ins

ENGL E765 Retro Tube

ENGL E765 Retro Tube

Modeled on one of ENGL’s most versatile amps, the E765 Retro Tube plug-in melds dynamic, old school clean and crunch tones with aggressive distortion textures that can subtly enhance a track — or take it over! Perfectly capturing the original’s 100‑watt EL34‑power section, as well as its powerful EQ and organic touch-sensitivity, the E765 Retro Tube plug‑in offers a full spectrum of tones — from pop to country, funk to hard rock.

ENGL E646 VS Limited Edition

ENGL E646 VS Limited Edition

Designed in conjunction with metal virtuoso and Rage guitarist, Victor Smolski, Engl’s E646 VS Limited Edition amplifier has become a favorite for players who crave the ultimate in high‑gain performance without sacrificing clarity. The E646 VS Limited Edition plug‑in delivers the same pristine, modern‑sounding clean tones, intense crunch, and over‑the‑top distortion as the hardware, giving you everything from the sonically sublime, to the extreme.

ENGL Savage 120

ENGL Savage 120

A go‑to legend for punishing metal tones, the Savage 120 Amplifier embodies ENGL’s rich legacy of vicious metal machines. A favorite of Exodus’ Gary Holt, as well as Dimmu Borgir, Sodom, and Primal Fear. The ENGL Savage 120 has metal bonafides to spare. the ENGL Savage 120 Amplifier plug‑in is an exacting emulation of this beastly, standard‑bearing tone monster

Fine-Tune Tones with FX Rack

Fine-Tune Tones with FX Rack

All ENGL amplifier plug-ins offer an onboard FX Rack that gives you potent tone sculpting. Tweak with Tight and Smooth filters, create crushing rhythm tracks with the onboard noise gate, or enhance solos with lo‑fi delay. You can also audition your tones through different signal paths, using various ENGL speaker cabinets, high‑end mics, preamps, and EQ emulations.

Unison<sup>™</sup> Technology for Apollo Interfaces

Unison Technology for Apollo Interfaces

Sounds like my real Savage 120

This plugin sounds great! I write and demo with the plugin. I use my real Savage 120 for tracking. Sometimes I can’t tell the difference!!!

wow. just wow.

today for the first time ever i decided i was going to buy the most unfairly priced plugin in the whole UAD system: a tuner that should be free but costs what like 60 bucks usually? cant remember. probably more. but i was ready to buy it. NOW, its not even available to buy by itself? i have to buy a whole bundle to TUNE A GUITAR OR BASS? thats plugged into UAD? i mean come ON! that is ridiculous. glad it gave me a reason not to purchase.

One of the very best guitar plugins

I am very cautious about plugins and hard to convince but this one, put in the Unison Channel, feels like a real amp. I am big fan of real valve-tube amps and have some in my collection and this plugin sounds great, big and, overall, very realistic.

Since I purchased the different Engl amp emulations, they are my go-to plugins for tracking guitars and now I avoid miking the real ones. Test it, this is a truly great plugin for guitar tracks.

A tuner should be included

So sad you have to buy a 200€ pack for this, there should be a UAD tuner

Grrr….What can I say?

Every tone possible

We all know most of the tone comes from the cabinet and mic choice. This amp has so many combinations that you can get any tone you want

ENGL is king, but I need to be able to load my own ir´s...

cannot buy it separately?

UA, that's is so, erm, strange I cannot buy only this plugin (needless to say maybe that one should be for free?)

Should be included for free

As all have said, not including at least a basic tuner isn't a good look for UA.

UA needs a free tuner

I will never ever pay money for this or be excited because it is included for free in a bundle

S. Vakis

Should be free or available as a stand alone plugin

Agreeing with everyone else here. Either make this free with console, or at least sell it as a stand alone 30$ plugin. DSP is slowly dying anyway, but a DSP tuner before your chain is a perfectly fine usage for it.

Eko eko eko....

what others say here. Not having access to a tuner without buying a bundle just feels really grubby. But then, Luna has no video facility. These scenarios should not be a work in progress but a total given. Seem's strange that now you made the leap to 'native' that using many elements of UAD means switching between DAW's. It's impossible to get everything right but, a tuner and a video facility is so basic. Just an idea, but put a call into brainwork and by the end of the working day we'll all be able to buy a tuner for $30. Or you could design your own in 24hrs. With a valve in it. Joking.

Come on UA!

This should be included, not as a tag on, to force you to buy some 300 guitar plugin package. REALLY?!!

Versatile amp sim

I was really surprised by this one. Much more than just a high gain amp. It's capable of of sparkling cleans, edge of break up, crunchy rhythm's, metal tones and searing leads. Well worth the price of admission.

Insane , No Tuner

How about UAD creating a simple Tuner , with the next console update ,
and it should be free .

I don't think this is much to ask for , Thank you .
