Brainworx has a really great variety of guitar and bass plugins so when they released a plugin based on this amp a few years back, I jumped on it immediately. The Mesa Dual Rectifier is the amp that may have started me down the gearhead path when I was real young watching all of my favorite bands use them. The versatility of most Mesa Boogie products is part of what makes them so popular. They seem to be able to just about anything while always adding it’s signature tone characteristics to the tone.

The list of famous and well known guitarists to use the power amp is a mile long so obviously there’s going to be more than a few Recto offerings out there. This one includes the amp, a cabinet section and a post-FX section.


Brainworx always puts a nice look on their sims so I wasn’t surprised to see this was no different. I was just say that the knob choice was a little odd but otherwise, she’s golden. Everything is laid out simple and easy without a lot of mystery. While the plugin does have the widest selection of controls of any Rectifier plugin, it’s still condensed from the real deal but the controls that are there respond pretty well.

If you have used a Mesa Dual Rec or heard one on an album, you know the tone and this sim will get you there. The gains are incredible with a lot of room to work inside whatever genre you choose. There’s really no genre or style that involves gain/distortion that the megadual can’t give you. Rectifiers give you so many ways to alter the amps tone that you can really use it for anything you want. Metal of any kind, punk, hardcore, rock, hard rock, the Dual Rec has been there, done it and still does it.

The onboard stuff is useful as always. They give you a gate, delay, some filters and an impulse loader with some nice selections. You can also bypass the power amp in favor of your own if you have something you prefer or just want to experiment with the amp. Every knob, switch and option you encounter in most Brainworx sims has a lot of value and impact on the tone.

The cleans are there and they are ok but usually with a Mesa amp, I prefer to use something else for cleans. It’s not a shot on the sim, it’s a shot on the original amp. Recto’s weren’t designed to excel as a clean amp but the clean tone is still workable. This is the reason you see many reputable Recto users using a second “clean” amp to handle that side of the tone.

I also had a great time testing boost pedals because the Megadual like it’s hardware counterpart responds really well to being kicked with a TS. Tube Screamers, OD pedals, Grid Slammers, you name it, I have probably put it out front of this plugin. A boost pedal and a Mesa Boogie amp very rarely let me down!

The cabinet section provides a decent amount of options but I feel this is the part of the plugin that could use an update. Brainworx has really started to put more time and effort into their cab sections so maybe giving this one a few new impulse response options would be an idea. However, when used with your own loader and impulses, it can tend to show off a little more. I have been using the Megadual and Megasingle with the Ownhammer MES 412 OS pack for years and it never fails to bring out the best in the plugin.


To this day, I don’t believe any developer has nailed down the Rectifier in plugin form but this one is the closest. It’s a few years old now and the regular price is a bit high but it does routinely go on sale so watch for it! There was also never a time where I thought the sim strayed too far from the true characteristics of Recto tones. I would recommend this one for said tones but I still wait patiently for the next high quality take on the powerful amp.
