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!

For this V2 version, JRAD were able to spend about 2 years living with an actual Dumble amplifier with the HRM EQ mod. This allowed them to really drill down on the subtle nuances to make a superior version to the original HRM pedal. This stompbox, even at lower gain settings, will bloom and feedback — making it feel just like the real thing.

One of the great happy accidents that occurred when developing their HRM V2, was that J. Rockett realised that the pedal can achieve some of the best Tube Screamer tones you could ask for — with more control over the EQ. The HRM V2 really is something special, and if you buy one, we're certain that it'll become a staple on your pedalboard!

EQ

While Ed Sheeran primarily relies on the natural sound of his acoustic guitar and vocals, he occasionally uses EQ (Equalization) to shape and enhance his tone during live performances or in the studio. EQ pedals or onboard preamps can allow him to adjust the frequency response of his guitar signal to suit the acoustics of different venues or to achieve specific tonal characteristics. Here’s how EQ might be utilized in Ed Sheeran’s setup:

1. **Tonal Shaping**: EQ can be used to adjust the balance of frequencies in the guitar signal, allowing Ed Sheeran to shape his tone to his liking. For example, he might boost the midrange frequencies to bring out the warmth and presence of his acoustic guitar, or cut certain frequencies to reduce any harshness or mud in the sound.

2. **Feedback Control**: In a live setting, EQ can help control feedback by notching out problematic frequencies that might cause the guitar signal to feed back through the amplification system. This can be particularly useful when performing in venues with challenging acoustics or high volume levels.

3. **Room Correction**: In situations where the venue’s acoustics are less than ideal, EQ can be used to compensate for any deficiencies in the sound. By adjusting the EQ settings, Ed Sheeran can tailor the guitar tone to sound more balanced and natural, regardless of the room’s acoustic properties.

4. **Matching Gear**: EQ can also be used to match the tone of Ed Sheeran’s guitar to the sound of other instruments or equipment in his setup. For example, he might adjust the EQ to complement the tonal characteristics of his vocal microphone or to blend seamlessly with backing tracks or other instruments.

Overall, while EQ may not be a central component of Ed Sheeran’s guitar effects setup, it can still play a valuable role in shaping his tone and ensuring that he achieves the desired sound in different performance environments. Whether used subtly for tonal shaping or more aggressively for feedback control, EQ allows Ed Sheeran to tailor his guitar tone to suit his musical vision and performance needs.

Overdrive

Like a golden layer of melted cheese — warm, gooey, and just put it all over. It adds just the right amount of richness and grit, turning a clean signal into something smooth and savoury. Designed to mimic the natural breakup of a tube amp pushed to its sweet spot, overdrive delivers the flavour of classic rock and blues in every bite. From creamy mid-gain warmth to crisp edge-of-breakup sparkle, it’s the comfort food of guitar tone — simple, satisfying, and endlessly versatile. Whether it’s a mild crunch or a full-bodied roar, overdrive is where good taste begins.
