A Much-welcome Update to a Modern Tube Amp Classic
The Revv Dynamis D20 MK2 represents the next evolution of the brand’s trailblazing tube head platform. This 20-watt tube amplifier head retains all the original D20’s most cherished cab-free features while simultaneously introducing a suite of MK2 enhancements, foremost of which is an updated and optimized revoicing of the circuit. Loaded with dual 12AX7s in the preamp and two 6V6s to drive the power section, the D20 MK2 sings with dynamic cleans and a gritty edge-of-breakup bite, along with enhanced headroom via its MK2 circuitry. Next, the D20 MK2’s embedded reactive load and virtual cabinet technology from Two Notes negate the need for a cabinet, allowing you to play and record cranked tube tones via the balanced XLR out or headphone jack without making a sound. And for those who clamor for the in-the-room roar of a guitar cab, the D20 MK2 also features 4-watt power scaling to grant you singing saturation at manageable volume levels. You also get a versatile 3-band EQ to shape your sound, a built-in footswitchable boost, a buffered series effects loop, and the MK2 additions of a treble-sharpening bright switch and lush digital reverb. It all adds up to an impeccable upgrade of Revv’s time-tested studio staple, combining cutting-edge functionality with the old soul of traditional tube amplification.

What's new in MK2?
First released in 2019, the Revv Dynamis D20 revolutionized the 6-string world with its blend of cab-free performance and unadulterated tube-powered tones. This MK2 revision shakes up the formula with a fresh circuit revoicing and superior headroom. What’s more, the D20 MK2 also introduces a lush digital reverb to save space on your pedalboard, along with a Bright switch to turn up the treble.


Embedded Two Notes tech for cab-free rocking
With just the D20 MK2 and a PA, you have everything you need to obtain a larger-than-life miked-cab tone. Built-in technology from the cabinet-emulation masters at Two Notes provides you with six customizable virtual cabinets selectable 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 D20 MK2’s 6V6-loaded power amp or bypass it and change the amp’s character with a simulated power section. KT66s? 6L6s? EL84s? EL34s? The options are endless! Best of all, D20 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 D20 MK2 delivers awesome tone.
Plenty of player-friendly features
The Revv D20 MK2 is loaded with everything a guitarist could want. A 3-band EQ and Volume and Gain controls give you tons of basic sound shaping. Want something a bit rowdier? A footswitchable boost gives the D20 MK2 a crunchier voice. A power-reduction circuit enables you to nail cranked tones at appropriate volume levels. A buffered series FX loop makes integrating your pedals and other external effects a piece of cake. The D20 MK2 also plays well with a variety of cabinets, thanks to a switchable 4/8-ohm speaker jack.


Top-notch tube tones developed with Nashville session guitarists
It’s easy to get distracted by the Dynamis D20 MK2’s endless bells and whistles, but even without its modern feature set, it’s a serious amp. And it should be — its tones were dialed in by Nashville session pros. 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, making a top-notch platform for gain pedals. Its crunch tones are bluesy and gritty, and when hot-rodded with an overdrive, downright raging. And its straightforward front-panel controls give you a ton of tonal space to maneuver in.
