Best-In-Class Looper with Saving and MIDI Sync Functions

Flex Prime’s USB connection opens up a world of recording and reamping directly to a computer. When connected, you can use the HeadRush Flex Prime as a 24-bit 96 kHz audio interface. The reamp function works by sending audio from your DAW through the Flex Prime and then recording it back into your DAW. This allows you to easily add nuance and tonal qualities only attainable with a hardware amplifier into their recordings. Any veteran studio professional will agree that this method saves valuable time and the HeadRush Flex Prime makes it easier than ever.

The HeadRush Flex Prime can integrate seamlessly into your current rig with a series of inputs to suit any and all of your performance needs.

The Flex Prime also features a 1/4” stereo FX loop to integrate external FX pedals at any point in your signal chain. This also allows for advanced integration with a traditional amplifier via the four-cable method. The USB-B port allows computer connection for firmware updates, audio interface functionality, and importing/exporting files directly to/from your HeadRush Flex Prime.

Brand

HeadRush

Headrush is a brand known for its cutting-edge guitar and bass equipment, particularly digital amp modelers, multi-effects processors, and pedals. The company focuses on providing professional-grade gear that delivers exceptional sound quality, versatility, and ease of use, making it a popular choice among musicians in live and studio environments. Headrush’s products are designed to offer realistic amp modelling and a wide array of effects, providing musicians with an all-in-one solution for shaping their sound.

One of Headrush’s flagship products is the Headrush Pedalboard, a powerful multi-effects processor that features intuitive touchscreen controls and advanced modelling technology. This device allows musicians to access a wide range of amp and effect models, all in a user-friendly interface. Headrush is known for its ability to deliver high-quality tones with minimal setup, making it ideal for performers who need reliable, versatile equipment. The company also offers the Gigboard and FRFR-108 speaker, further expanding its range of tools designed to offer both studio-quality tones and live performance flexibility.

Delay

A delay pedal records your signal and plays it back after a set time, creating echoes that can range from tight, slapback repeats to long, atmospheric trails. It’s one of the most versatile effects, used to thicken tones, add rhythmic depth, or build spacious, ambient layers. Analogue delays offer warm, decaying repeats that blend naturally with your tone, while digital units provide pristine echoes with precise control over time, feedback, and mix levels.

From classic rockabilly and tape-style echoes to modern looping and shimmer effects, delay pedals have become essential tools for shaping sound. They can make solos soar, rhythms pulse, or transform simple chord progressions into cinematic textures. Whether used subtly to add dimension or boldly to create soundscapes, a good delay pedal can completely redefine the feel and atmosphere of your music.

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.

Expression

Expression pedals allow real-time control over specific parameters on compatible guitar pedals, such as volume, delay time, modulation depth, or filter sweep. Used with an expression input, they let players shape effects dynamically with their foot, adding movement and performance control that cannot be achieved with fixed knob settings.

Fuzz

A fuzz pedal is one of the earliest and most aggressive forms of distortion, turning your clean guitar signal into a thick, saturated wall of sound. It works by clipping the waveform almost flat, creating a compressed, gritty tone full of harmonic overtones. The result is raw, unruly, and unmistakable — from the sputtering breakup of vintage germanium circuits to the searing sustain of modern silicon designs. Fuzz pedals react strongly to your guitar’s volume and pickup choice, making them dynamic tools for expressive players.

Whether you’re chasing the classic tones of Hendrix and the Smashing Pumpkins or exploring heavy, experimental textures, fuzz remains a favourite for its personality and unpredictability. It can sound smooth and sustaining, or wild and velcro-like, depending on how it’s set up. A good fuzz pedal cuts through the mix while adding thickness and attitude, turning any riff or lead line into something bold and unmistakably alive.

MIDI

MIDI pedals use the Musical Instrument Digital Interface standard to communicate with other guitar pedals, effects units, and hardware. They allow control over presets, parameters, and switching across multiple devices from a single controller. MIDI integration makes it possible to build complex, synchronised pedal setups while keeping control simple and consistent.

New

This is brand new, fresh in, and a UK warranty is included. New Gear always comes from trusted UK music retailers.

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.

Reverb

A reverb pedal is like the rich sauce that ties every flavour on the plate into one smooth experience. It adds depth, warmth, and atmosphere — the sonic equivalent of a perfectly reduced glaze that lingers on the tongue. Whether you’re after the subtle ambience of a cosy café (spring or plate reverb) or the grand echoes of a cathedral (hall or shimmer reverb), this is where your tone breathes and expands. A touch of reverb can turn a dry sound into something lush and inviting — but pour on too much, and it’s all you can taste. Used with finesse, it’s the finishing touch that transforms your tone from plain to unforgettable.

Tuner

A tuner is an essential pedal or device that helps keep your guitar perfectly in tune by detecting the pitch of each string and showing whether it’s sharp or flat. Tuners come in many forms, from simple clip-on units to advanced pedalboard models with bright displays and muting options for silent tuning on stage. They ensure accurate pitch, stable tone, and a more professional sound, making them one of the most important tools for any guitarist.

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.
