Guitar World Verdict

We obviously can’t say that we compared the HRM V2 to an original Dumble amp, but it’s certainly in the ballpark of tonal qualities that one might expect. It’s a beautifully voiced drive pedal of the sort that, once you’ve started, encourages you to keep playing.


  • +

    Solid build-quality.

  • +

    Compact size.

  • +

    Excellent sound quality.

  • +

    Solid EQ options.


  • -

    None if you want a D-style pedal, but expensive if you just want a drive pedal.

Alexander Dumble didn’t build many amplifiers in his lifetime, so if and when one comes up for sale it’s going to be for silly money. Fortunately, there are some pedal manufacturers out there that have a handle on how to get close to the Dumble feel and tone – and that includes J. Rockett. 

In its lineup, J. Rockett has a pedal called The Dude, which was based on a Dumble Overdrive Special amp owned by Keith Urban. It also had another pedal, the Hot Rubber Monkey (HRM), which featured the brand’s interpretation of an ODS with an EQ modification.
