On the menu for January 2026 are the Diamond Guitar Pedals, freshly added and carefully selected. These New units are available to order online with fast, secure delivery from trusted UK retailers.

The concept for Diamond Pedals’ Boost/EQ began in the early 2000s, with a request for a ‘compression-less’ version of the famed Diamond Compressor – combining a clean boost circuit with the Compressor’s Tilt EQ.

Nearly 20 years after the resulting original pedal’s launch, we’ve re-imagined this idea on the same platform as the Comp/EQ. Introducing the next-generation Diamond Boost/EQ. This versatile, low-noise pedal delivers a punchy, dynamic sound that’s ideal for any set-up.

Key Features  

  • Clipping Options – Switch between a pure clean boost with up to +20 db of volume on tap (up position), or add a touch of light transparent soft clipping overdrive in the down position.
  • Versatile EQ – With controls for the Tilt EQ (800 Hz +/- 6dB Tilt EQ Fulcrum Frequency) in partnership with a separate Mid frequency control (800 Hz +/- 10dB Mid EQ Centre Frequency), dialing in your perfect tone is quick and easy!
  • Diamond Quality – The Boost/EQ is hand-made in Canada using high-quality parts and components.

Hands on

Taking the lively, high-fidelity gain stages of the Comp/EQ, the Boost/EQ offers plenty of punch while maintaining clarity and transparency. While the Tilt and Mid controls give you complete freedom to sculpt your tone. Need more sparkle? Dial it in with the Tilt knob. Looking for a midrange boost to cut through your solos? The Mid control has you covered. Want to make your Marshall tone a bit more Fender-esque? It’s all possible with Diamond’s Boost/EQ.

And a Low-Gain Drive

In addition, the Boost/EQ features a second mode that provides a low-gain overdrive – transparent, yet full of character. This makes the Boost/EQ the ultimate Swiss Army knife for your pedalboard, combining clean boost, tone shaping and overdrive, into one powerful and versatile pedal.

The Boost/EO offers 2 distinct modes of operation. The first is a clean boost mode designed to increase the output of your signal enabling you to beef-up low-output pickups, drive tube amps and dirt pedals for increased sustain and saturation or simply have your solos jump out in the mix.

Set to the OD mode, the gain structure of the pedal is modified and soft clipping diodes are added to the circuit. This provides smooth, transparent, musical distortion that ranges from just a touch of hair and harmonic overtones, to a nice low to mid gain overdrive.

Depending on where your Boost/EO is placed in your signal chain, it will either deliver an increase in volume or distortion/saturation. Place it at the end of your pedal chain or in an amp’s series FX loop for a volume boost. Put it in front of your drives and fuzzes for more gain and distortion.

Specifications

  • Top-mounted jacks and soft touch relay switching
  • True Bypass
  • Hand-made in Montreal, Canada
  • Powered by a regular 9-18 V DC PSU (centre -, 2,1 mm, ~18 mA current draw)

Distortion

Distortion pedals take your clean guitar signal and transform it into something bigger, bolder, and full of attitude. By clipping the waveform, they add sustain, bite, and aggression, creating that thick, compressed tone that’s powered rock music for decades. From the growling crunch of classic hard rock to the tight, saturated roar of modern metal, distortion is all about energy and presence. It gives every note weight and authority, pushing your amp to its limits and beyond.

There are countless flavours of distortion, each with its own texture and edge. Some sound smooth and creamy, others raw and gnarly like tearing fabric. It’s the sonic equivalent of turning up the heat until the sound cooks — rich, sizzling, and perfectly seasoned to taste. Whether used for rhythm muscle or soaring leads, a good distortion pedal doesn’t just add volume; it adds personality, grit, and that unmistakable sense of power under your fingers.

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.

Volume

Volume pedals control the output level of a guitar signal using a foot-operated treadle. They allow smooth volume swells, dynamic control during playing, and easy muting between songs. Volume pedals can be placed at different points in the signal chain to either control overall loudness or adjust gain and drive behaviour when positioned before distortion or overdrive pedals.
