Now You Can:

  • Track through the legendary 100-watt ENGL E765 Retro Tube amplifier on Apollo-equipped workstations
  • Craft old-school clean tones and aggressive overdriven sounds easily and intuitively
  • Audition 64 different Recording Chains with a selection of mics, cabinets, and outboard gear
  • Fine-tune your sounds with an onboard FX Rack, including noise gate, EQ filter controls, and host-syncable lo-fi delay

ENGL Amps: A 20-Year Legacy

More than two decades after its inception, ENGL guitar amplifiers continue to deliver cutting-edge tone machines to some of rock and metal’s most legendary players. With their complex clean textures and searing distortion, it’s no wonder these coveted tube amps have become a staple in studios and stages worldwide.

Designed in conjunction with Brainworx, the ENGL E765 Retro Tube plug-in brings one of ENGL’s flagship amps directly to your UAD-2 DSP Accelerator or Apollo-equipped workstation. The two channel ENGL 765 Retro Tube plug-in also sports an FX Rack to broaden your tonal palette.

A Full Spectrum of Tone

Channel One’s three-dimensional clean tones will impart your tracks with a complex sparkle and harmonically rich chime, whether you’re plugging in a single-coil or humbucker-equipped guitar perfect for lilting arpeggios or funky rhythmic stabs. 

By tweaking Chanel One’s Gain control, you’re able to take advantage of the ENGL E765 Retro Tube plug-in’s superb dynamics, as you can dial-up clean-ish, just-on-the-verge-of-breakup, crunch textures that will add power, definition, and texture to your tracks.

Channel Two’s more aggressive voice gives you a myriad of intense rock tones that run the gamut from classic tube snarl, to modern sledgehammer distortion. Like the original amplifier, the ENGL E765 Retro Tube plug-In reacts to your playing attack exceptionally well — no matter how much gain you’re using. From de-tuned rhythms to singing leads, the ultra-musical string-to-string detail stays intact.

FX Rack — Find the Perfect Sound for the Perfect Part

The ENGL E765 Retro Tube plug-in’s FX Rack adds another level of sonic versatility to your workstation, with pre/post EQ filter controls, a noise gate, Power Soak, and host-syncable lo-fi delay. The crown jewel of the FX Rack, however, is the 64 powerful Recording Chain presets, which allow you to audition your tones through a variety of vintage mics, ENGL cabinets, and outboard gear, including hardware emulations from Millennia, SPL, and elysia.  

Captured through Brainworx’s Neve VXS72 board, the Recording Chain presets are akin to an engineer patching you through various high-end signal chains, but with a single mouse click instead of time-consuming rerouting. You can even set this feature to scroll through the various Recording Chains in one, two, or four bar increments, allowing you to keep your hands on your instrument while listening to the sonic differences.

    one of the more usable amp modles for sure
    by . (Thursday 16 June, 2016)

    I am usually pretty underwhelmed by digital amp models but this one is pretty decent. I get a lot of really usable tone both clean and over-driven. Not a whole lot to say...a lot of vintage and modern tones in this one. Read More

    Thanks for the bypass preamp feature!
    by M. Niemczyk(Wednesday 13 April, 2016)

    Thank you so much for the most important Feature for real preamp owners which is bypassing the software emulated preamp! I´m sure most guitar players have already a nice sounding real tube preamp or a head with DI out, which they really want to use in every possible situation. I´m a proud… Read More

    ENGL® E765 Retro Tube
    by j. Dietzel(Friday 15 January, 2016)

    This amp works great. It gets used a lot when I dont feel like micing up a cab, and I never feel the need to replace it later. Only problem is how every preset has the bass Blasted to 10. easy to turn the knob back, but I dont know why they did this. I would recommend this is your looking… Read More
