The J. Rockett HRM V2 is designed to achieve the overdriven sounds of a legendary D-style amp with the acclaimed HRM ("Hot Rubber Monkey") EQ mod — a popular modification by Howard Dumble where additional gain stages and tonal options were fitted to enhance the versatility and the sonic capabilities of his highly sought-after amps. This custom EQ creates a very low-mid centric, throaty sound where the guitar frequencies thrive — it's sonic bliss!
