Revv Revv D20 White

A "next-generation" amp from Revv, designed for speakerless playing

With the D20, Revv offers a compact "lunchbox"-style head that combines tube feel with a decidedly modern approach to guitar amplification. The idea is simple: get your amp sound both on a traditional speaker cabinet and direct (console, interface, in-ear monitors), without relying on microphone miking. The D20 stands out by integrating an internal reactive loadbox and a Torpedo simulation engine, making it a particularly coherent solution for musicians who want to travel light without sacrificing the character of a true tube power section.

Who is the Revv D20 made for and in what situations?

The Revv D20 targets guitarists seeking a simple-to-set-up head that's flexible enough to cover many contexts: rehearsal, studio, live performances direct to console, or home practice with headphones. At 20 watts, you have enough headroom to play with a drummer (depending on cabinet and style), while the 4-watt mode facilitates lower-volume practice while retaining tube behavior.

Regarding styles, its voicing suits registers where you want to feel the dynamics under your fingers: blues, rock, indie, pop, worship, and broadly anything that benefits from a solid clean/crunch foundation. Thanks to its gain and transparency, the D20 also excels as a pedal platform (overdrives, fuzz, delays, modulations), whether you play through a cabinet or direct.

Key features: switchable power, built-in Torpedo, presets, and pro connectivity

The D20 is an all-tube head equipped with 2x 6V6 power tubes and 2x 12AX7 preamp tubes, with a selectable output from 20 to 4 watts. The control section is straightforward with Gain, Volume, and a 3-band EQ, complemented by a push/pull on the Gain for accessing a second, crunchier voicing. This allows quick switching from a tight clean base to a more saturated tone without complicating the ergonomics.

Its major asset lies in the integration of a reactive loadbox that automatically engages when no speaker is detected, to protect the tubes. In loadbox mode, a Pre/Post selector lets you include or bypass the power amp section in the signal chain: useful for choosing between a more "preamp direct" response or a fuller sound including the power section's personality. The amp also features virtual speakers (selectable on the front panel) and built-in processing (mics, EQ, and reverb) tailored for direct recording, silent playing, and live use.

Going further, the D20 accepts MIDI presets (up to 128) and offers connectivity designed for modern rigs: balanced XLR DI with Ground Lift, USB for editing/connection, and a headphone output with adjustable level. Finally, the series effects loop with buffer facilitates integration of delays and reverbs after distortion, maintaining a clean and stable signal.

The Sound

The Revv D20 delivers a typically all-tube character: an organic attack, pleasant natural compression when pushing gain, and a real "bounce" feel under the fingers. The clean tones remain detailed and dynamic, ideal for pick or fingerstyle playing, while the crunchy voicing accessed via push/pull brings a more biting saturation, perfect for tight rhythms and expressive leads.

When used with a cabinet, the D20 maintains great clarity and a very "pedal-friendly" response. Direct (DI/USB), the Torpedo simulation and reactive loadbox aim to recreate a feel closer to a "amp + cabinet" mic'd sound, with immediate coherence for recording or sending a mix-ready signal. Whether you seek a solid clean base, characterful crunch, or a reliable foundation for your pedals, the D20 positions itself as a modern head without compromise on tone.
