All Tube Amp Head:

Think you need a cabinet to achieve an awesome miked-cab tone? Not if you’re playing through a Revv D20 amp head. The D20 is an all-tube amp head — with glowing-hot 6V6s and 12AX7s. Thanks to embedded reactive load and virtual cabinet tech from Two Notes, the cab is optional. Includes a 3-band EQ, Volume and Gain controls, along with a push-pull gain pot for a crunchier voicing and a power-reduction circuit to attain cranked-amp sounds at lower volumes. A buffered series FX loop sweetens the pot. The Revv D20 is a great sounding Amp with tons of modern features.

Embedded Two Notes tech for cab-free rocking:

With just the D20 and a PA, you have everything you need to obtain miked-cab tone. Built-in technology from cabinet-emulation masters at Two Notes provides you with six customizable virtual cabinets selectable via the amp’s front panel. You can access up to 128 via MIDI as well. You can use the D20’s 6V6-loaded power amp or bypass it and change the amp’s character with a simulated power section. KT66s? 6L6s? EL84s? EL34s? The D20 is a complete standalone solution — a reactive load automatically engages when a speaker isn’t connected to safeguard your amp. The D20 delivers awesome tone whether you go direct to FOH, an audio interface, or headphones.

Killer tube tones developed with Nashville session guitarists

The D20's tones were dialed in by Nashville session pros. With all the embedded tech bypassed, when cranked it up, it’s a winner. Its clean tones are warm and inspiring, and they make a top-notch platform for gain pedals. Its crunch tones are bluesy and gritty, and when hot-rodded with an overdrive, downright raging. Straightforward front-panel controls give you a lot of tonal space to maneuver in.
