Revv’s Flagship Fire-breather

While it’s clearly built for high-octane metal, the Revv Generator 120 MKIII has something to offer every player. Want super-articulate high-gain with laser-like clarity? A sludge-infused sledgehammer? Enough pushed crunch to pave the highway to hell? How about no-compromise cleans that would make any Nashville picker jealous? This 120-watt, 4-channel tube head does it all. And there’s plenty of room for customization, thanks to an array of sonic-sculpting controls, including powerful, per-channel 3-band EQs. You also get convenient power scaling, a serial effects loop for your pedals and processors, a studio-quality digital reverb and noise gate, and stage-worthy Bluetooth and MIDI control capabilities. To top it off, the Generator 120 MKIII boasts a stereo-out reactive load and cabinet simulator, powered by Two Notes Torpedo-embedded technology. The Generator 120 MKIII is Revv’s flagship, and it’s a triple-digit-watt fire-breather. No matter what hard-hitting genre you prefer — thrash, death, doom, black, or sludge metal; metalcore, deathcore, or grindcore; hardcore punk or crust punk; neoclassical, symphonic, or speed metal — this high-gain titan will exceed all expectations.

Brimming with player-friendly features

The Generator 120 MKIII starts with four revoiced channels of signature Revv tone, including their Purple channel, which is celebrated for its tight, articulate sound, and their Red channel, which is lauded for its fat, saturated sound. And, as you’d expect from Revv, both channels deliver punishing levels of gain. Per-channel 3-channel EQs eliminate tonal compromises when switching between clean, crunch, and high-gain tones. Global Wide, Drive, and Aggression switches put a myriad of saturated textures at your disposal. Bright switches add extra bite and presence when it’s called for, while midrange-sculpting Cut switches allow you to toggle between a bright, biting sound and a deeper, scooped-style distortion on the overdrive channels. You also get a Fat switch on both drive channels to thicken your high-gain tones. Power scaling facilitates muscular tones at bedroom-friendly levels, while a serial effects loop accommodates your pedals and other processors. A configurable and bypassable digital reverb and noise gate yield a polished, studio-quality result. The Generator 120 MKIII plays well with a variety of cabinets, too, thanks to a switchable 4-/8-/16-ohm speaker jack. You also get an easily accessible bias test and fuse.

Embedded Two Notes Torpedo tech for stereo, cab-free cacophony

With just the Revv Generator 120 MKIII and a PA, you have everything you need to obtain a larger-than-life miked-cab tone, thanks to embedded Two Notes Torpedo technology and the amp head’s stereo XLR outputs. Select between six customizable virtual cabinets via the amp’s front panel; if that’s not enough for you, you can access up to 128 via MIDI as well. You can use the Generator 120 MKIII’s EL34-loaded power amp or bypass it and change the amp’s character with a simulated power section. KT66s? 6V6s? EL84s? 6L6s? The options are endless. You also get the Two Notes Twin Tracker stereo doubler, an equalizer, an enhancer, and more — all editable via Bluetooth. Best of all, the Generator 120 MKIII is a complete standalone solution: a reactive load automatically engages when a speaker isn’t present to safeguard your amp. Whether you go direct to FOH, an audio interface, or headphones, the Generator 120 MKIII delivers awesome tone with killer effects — in stereo!

Delivers killer tube tones

It’s easy to get distracted by the Generator 120 MKIII’s endless array of sonic toys. But even without its modern feature set, it’s a killer amp. At Sweetwater, we bypassed all the embedded tech and cranked it up, and everyone agreed that it’s a winner. Its clean tones are warm and inspiring, and they make a top-notch platform for gain pedals. Its high-gain tones are downright raging — tight, full, and expressive. And its straightforward front-panel controls give you a lot of tonal space to maneuver in.

A fantastic machine

This is one of the best amps I have ever heard. Certainly the best amp I've ever owned. Every channel is usable and fantastic. I was overly impressed with every single thing about this amp.
Rated 5/5

Purple is my new favorite color

I don't ever write reviews on gear but I had to for this. The amp is frickin incredible. I've always been a huge fan of the rectifier sound. My ears are changing though. I just can't get them to sound good under my fingers anymore. I watched a couple videos on the smaller G20 and was blown away. I wanted to buy a "rig" though since I'm just one of the guys that likes 4x12s lol. I went back and forth for weeks between the 100R and the 100R and ultimatly just decided F--- IT I WANT BOTH.

I'm gonna start with the built TwoNotes because this addition just pushed this amp into another territory value wise. It sounds excellent. The Revv 412 in there sounds great. I actually ordered a matching cab for the amp after hearing the IRs.

The Reverb and noise gate are top notch on here. They really round out the "extras"

I'm not gonna get super descriptive on the tones but the clean is very good. It can break up if you want it too and the wide switch adds a nice boost. Channel two hits really chimey crunch tones with ease. Some of you might live on this channel. All three boosts are usuable and add a touch of gain.

PURPLE! This is my channel. OMG is it good. This is where Revv stole me away from Mesa. It's like a refined 5150/Recto but with a really sweet midrangey crunch. The gain is usuable for the whole sweep. Red channel is a little more bottom focused to my ear. It's no purple channel but it's still very good.

The boosts are great on here. I haven't even tried a boost pedal with it. Doesn't need it.

I have the matching cab with WGS Veteran 30s. Well built cab. They even customized it with the smaller LED nameplate to match the head. Looks really cool.

The value is incredible. Great job REVV! Shout out to Aaron T. at Sweetwater. He jumps through hoops to get me what I want. Thanks for all your help!

Most Versatile Amp I Own

I'll start off by saying I've played mainly Mesa Boogie amps for 20+ years but wanted to expand my arsenal so to speak. I was initially looking at a Diezel VH2 but my sales dude Dave Cody steered me towards this amp. I had seen a number of reviews and demos online but for me it's hard to get the feel and nuances of an instrument or amp without testing it out in person. Dave was able to go down and run the amp through its paces for me and give me really excellent feedback. I went with his recommendation and I was not disappointed.

I play a wide range of styles as well as a lot of recording and this amp does everything I need and then some. The clean channel sparkles, the crunch channel is very reminiscent of a Marshall, and the red channel is punishing. But the Purple channel is where this amp truly shines. It has some flavors of a Rectifier but is more focused and it cuts through the mix like a knife. The aggression modes allow for further customization so you can really dial in your sound. The foot switch allows you to access all the channels as well as aggression modes, FX's and Master Volume. Switching in between is a breeze.

The only thing that didn't blow me away was the imbedded Two Notes Torpedo. But that's just my opinion on it.

Bottom line, if you are on the fence, just get it. You will not be disappointed.

Does so much more than simply modern metal

I own an old 1990 MESA Mark-IVa, so I've kinda run my course with MESA and wanted something (modern sounding) with its own personality & character. Revv caught my eye.

It doesn't sound like a Marshall, 5150 or a MESA, and that uniqueness is what I was looking for. Those tones are not in this amp, and I'm fine with that because I was looking for something different.

I ordered this amp without ever having played one in person, simply relying on Youtube reviews. So, with that being said, I was already aware of it's wonderful, percussive modern metal tones.

I was able to achieve great tones across the board with all the EQ knobs at 12:00, right out of the box.

What surprised me was just how versatile this amp is for other types of music. I discovered the Green channel to be quite pristine, and with my Big Sky I was even able to achieve some stunning ambient clean patches. The "wide" switch adds a lot of character to this channel.

Blue channel feels like a continuation of the Green (I LOVE how the four channels all feel like a continuation of the previous channel, a lot like my Bogner). A bit more gain, very suitable for classic rock up to the 80's hair metal. I keep the gain on most tube amps at around 2:00 to start with, and I found this to be perfect with the Blue channel.

Purple channel is quite special, likely the best sounding (and most versatile) channel of all. It has a wonderful, articulate metal rhythm tone. Some people may find the REVV amps "unforgiving", but then again so are the MESA Mark series. First thing I did was set the gain at 2:00, engage the bright and fat switches with a tiny bit of plate reverb from the Big Sky. I then just slowly strummed some open chords around the first fret. The harmonic complexity present in this amp is just breathtaking. Despite the intense gain at 2:00, every note of the chord could easily be heard. Rolling off the volume yielded beautiful "edgy" tones that still retained that harmonic complexity without losing valuable top end.

Red channel feels like a continuation of the Purple, with even more gain and saturation, likely aimed at lead playing. HOWEVER, despite this increased saturation, chords still retained their character and don't turn to mush. Turning the gain past 2:00 wasn't much to my taste because of the amount of saturation, but the amp never loses its character.

The reverb, while digital, is quite nice to be honest and surely fits the bill if one forgets to bring their effects pedal to a gig.

One other thing, plugged in and turned on with pedals in the loop, with the guitar volume off my amp is completely silent through the cab. This is without the noise gate being engaged.

I found the noise gate to be very effective. I just turned the knob to about 10:00 and I was able to still achieve great sustain without premature silencing of the notes. Just a wonderful addition.

I still haven't started messing with the IR's provided by what is essentially a Two-Notes Captor installed in the amp.

The amp itself is built like a tank, and weighs as much as one. All the knobs and switches speak high quality. Everything just looks and feels professional. The footswitch, while more lightweight than I expected, is still sturdy enough for touring.

Speaking of "professional", it's a flagship amp and is priced as such. I'm not even a gigging guitarist, and I have no regrets dropping $ for this amp. The harmonic complexity I heard on day one convinced me this was "keeper"

I proudly rate this REVV amp in the same realm as my beloved Bogner Ecstasy.

Check it out folks, and if you don't like it you can always return it.

Incredibly Versatile

This is easily the best sounding amp I've ever played. I mainly play heavy metal, and the purple channel on this amp through a great cab produces album-ready tones with very little tweaking required. It's definitely got the sound in my head when it comes to perfect tone. It's got a great midrange while still maintaining that upper mid bite common in a lot of modern metal. The built-in gate works extremely well, especially for extremely tight "djent" tones.

The red channel is also fantastic, my leads cut through extremely well when playing live. The mid content is extremely rich and sounds very smooth, with basically no high end harshness. The reverb also sounds very good even through a cab. This channel is fatter sounding than the purple with higher gain, which can be great for "looser" styles of metal.

I've even done some red hot chili peppers style guitar with the green and blue channels and they also sound incredible (hence the title of this review). This amp really does it all.

I've seen others talking about the price of this amp online, but one factor that I think makes the price worth it is the built-in loadbox. To get a quality loadbox outside of an amp would probably cost anywhere from $1-2k. If you consider the price of the amp plus the loadbox, I feel like it's actually in a price range similar to other high-end amplifiers.

Speaking of the loadbox, it works very well! You can record a direct in to your interface with just the amp by itself (no cab needed). You can also use the loadbox at the same time as the cab, which is one of the main reasons I purchased this amp. I use the loadbox as a direct out from the amp to record myself while practicing with my band. I also plan to use the direct out live to provide a record-quality tone to FOH while still playing through a cab.

TLDR - This is an incredible sounding amp with every feature any guitarist could need. Definitely the best amp purchase I've ever made.
