Guitar World Verdict

The G20 is practical and packed with gain. With the onboard Two Notes tech, it's a phenomenal recording tool, but its compact format means it's one for the road, too.


  • +

    Great overdrive sounds.

  • +

    Huge choice of world-class cab sims.

  • +

    Compact and very portable with a smart carry case included.


  • -

    An occasional slight pop on this sample when switching from overdrive to clean sounds.

Founded in 2014 by Dan Trudeau and Derek Eastveld and based in Winnipeg, Canada, Revv Amplification is the go-to backline for artists as diverse as metal god Jeff Loomis and Nashville session star Jeff King, along with many of Canada’s best-known rock guitarists. 

Like most amp manufacturers, Revv saw the potential of a compact ‘lunchbox’ product but wanted to take things to a new level. Its D20 head certainly achieved that, being the world’s first amplifier to integrate the award-winning Two Notes Torpedo reactive load and cabinet emulation technology.
