ENGL® E646 VS Limited Edition Plug-In
developed by Brainworx

A High-Gain, State-of-the-Art Tone Machine, Meticulously Modeled.

The ENGL E646 VS Limited Edition plug-in for UAD-2 and Apollo hardware offers expansive clean tones and cutting-edge high-gain technology for the ultimate rock amp.

Now You Can:

  • Track through the ferocious ENGL VS Limited Edition amp with near-zero latency on your Apollo-equipped workstation
  • Perfectly sculpt clean tones, muscular chunk, and searing high-gain sounds with remarkable string-to-string definition
  • Fine-tune your sounds with an onboard FX Rack that contains a noise gate, filter controls, and host-syncable lo-fi delay
  • Audition 64 different high-end Recording Chains with a selection of mics, cabinets, and outboard gear 

ENGL’s Heavy History

For over 20 years, ENGL amplifiers have become synonymous with high-performance rock and metal guitar tones. With their signature detailed clean sounds and dynamic, molten distortion, ENGL amps power the stages of some of rock’s biggest artists. Designed in conjunction with legendary Rage guitarist Victor Smolski, the ENGL E646 VS Limited Edition amplifier has become a modern classic among players looking for a versatile, high-end amplifier that can range from sparkling clean textures to searing high-gain tones.

Developed by Brainworx, the ENGL E646 VS Limited Edition plug-in is a sonic dead-ringer of this ferocious amplifier for your UAD-2 DSP Accelerator or Apollo-equipped workstation.

Unlimited Attitude, Unlimited Tones

With four channels, the E646 VS Limited Edition plug-in covers all the bases, and then some. With a Gain control for each channel, you’re able to dial in the perfect amount of touch-sensitive responsiveness to your clean and semi-distorted tones. With a twist of the wrist, you can easily add heft to Channel One’s crystalline clean sounds, or render some harmonic “hair” around Channel Two’s chunk flavors.

Channels Three and Four offer a ton of gain with exceptional string-to-string clarity, allowing your heavy rhythm and lead tones to speak with unparalleled precision and power. The E646 VS Limited Edition plug-in’s EQ fine-tunes your sounds just like the hardware version. The Depth Punch control accentuates the thump of a 4x12 cabinet, while the Presence control expertly sculpts your high-end frequencies to musically cut through a mix. You can also hone in on the all-important midrange frequencies for scooped-mid rhythm tones or fat, singing lead lines rife with juicy harmonic detail. Clean to mean and all points in-between, the ENGL E646 VS Limited Edition plug-in injects your studio with a stunning array of firepower.

Obey the Sounds — and the Flexibility

The E646 VS Limited Edition plug-in offers new tools that greatly add to its versatility when tracking guitars. The FX Rack features an onboard noise gate, host-syncable lo-fi delay, Power Soak, and pre/post switchable EQ filter controls, allowing you to put the finishing touches — before or after mixdown — on your tones.

But it’s the E646 VS Limited Edition plug-in’s 64 Recording Chain presets that give you the ultimate in flexibility. Captured through Brainworx’s ultra-rare Neve VXS72 console, these presets let you audition your sounds through a variety of vintage mics, ENGL cabinets, and outboard gear, including hardware emulations from Millennia, SPL, and elysia. It’s akin to an engineer patching you through various chains and mic placements. You can even set this feature to scroll through the Recording Chains in one, two, or four bar increments — allowing you to keep your hands on your instrument while listening to the various flavors.

    Very Impressed With ENGL
    by D. Bires (Thursday 3 April, 2014)

    I have searched long and far for a Guitar Plugin That Boasts a sound like this. Let me sum this up to the importance of why this plugin is the real deal. Its very simple. I fired this engl up and I heard what I have been hearing for years when I mic a cab. You can hear the mics and say that is a shu … Read More

    Sounds like an ENGL
    by A. Cooper (Wednesday 5 February, 2014)

    You know I see all these negative reviews of this product and I just don't get it. I own an ENGL and this thing sounds pretty damn close for a sim. I see that one of the reviews was stating that they wanted classic tones for classic rock but yet they bought this version of the plugin, Well that's ki … Read More

    Ch Ch Chunky!!
    by P. Boshart (Saturday 7 December, 2013)

    You want it, you got it. Hands down the best hard rock tones I have ever used. The ENGL E646 VS is a monster. I have to say I have been using amps, and amp plug ins for my production for years, and have been looking for this type of tone from a Plug in for a long time. The benefit of it being such l … Read More

    I had no high expectations when I read those first reviews. It took a long time before I tested this amplifier. But when I finally tried, it took me 30 minutes to be convinced. This is the guitar simulator I've tested that sounds closest to a micked amplifier. I had Nigel in mind but this is so much … Read More

    Engl baby
    by J. Alea (Monday 23 September, 2013)

    I really like the sounds that I can get from this amp sim. It sounds great distorted, but the clean sounds are also very nice. I use an EMG equipped guitar with this sim and it just really roars. If I am searching for a clean tone, then it can also do the trick. I would normally knock down my rev … Read More
