Hot rodded Dumble tones at your fingertips.

The J Rockett Hot Rubber Monkey HRM V2 overdrive is your ticket to overdriven Dumble tones!

Featuring a meticulously designed EQ mod, the HRM V2 creates a low-mid centric and throaty sound that perfectly captures iconic Dumble HRM sounds.

Featuring exceptional touch sensitivity and quick response, the HRM V2 ensures your playing cuts through the mix with authority.

J Rockett went above and beyond in the development of this new version, spending two years with an actual Dumble amp equipped with the HRM EQ mod. This allowed them to fine-tune the pedal and capture even more of the amp’s subtle nuances.

Even at lower gain settings, the HRM V2 blooms and feedbacks just like the real thing, providing an amp-like playing experience.

J Rockett went the extra mile by incorporating carefully sourced NOS parts, making it an absolute joy to play.

Experience the power and versatility of the J Rockett HRM V2 and unleash hot-rodded Dumble tones like never before!
