The Maestro Invader Distortion pedal is a powerful distortion unit designed to deliver a heavy, aggressive sound packed with rich harmonics. Perfect for guitarists seeking a dominant and versatile distortion tone, this pedal offers intuitive control with its simple three-knob layout featuring Gain, Tone, and Level. Whether you want to dial in subtle grit or full-on high-gain saturation, the Invader provides ample volume and sonic character to invade your soundscape and dominate the stage.

One of the standout features of the Invader is its onboard noise gate, which can be easily engaged via a top-panel toggle switch. This built-in noise gate helps keep your tone tight and free from unwanted hiss or feedback, especially useful when pushing high gain settings. An internal trim potentiometer allows you to fine-tune the gate threshold to suit your playing style and rig, ensuring maximum clarity without sacrificing sustain.

The pedal’s true bypass footswitch ensures your signal remains pure when the effect is disengaged, while the LED-lit bugles in the Maestro logo provide a clear visual indication when the pedal is active. Compact yet robust, the Invader is powered by a 9V battery or a regulated 9V DC power supply, making it a reliable choice for both studio and live use.

High-gain distortion

The Maestro Invader delivers a thick, aggressive distortion tone full of harmonic richness. Its all-analogue design preserves the natural dynamics of your playing, offering everything from crunchy overdrive to searing gain with effortless control.

Onboard Noise Gate with Adjustable Threshold

Keep your tone tight and focused with the built-in noise gate. Easily toggle it on or off, and adjust the threshold internally to suit your setup and eliminate unwanted noise.

Simple, intuitive controls

With just three knobs — Gain, Tone and Level — you have complete control over your distortion sound. Shape your tone quickly and easily, and boost your output to cut through any mix.

Key Features

Boost

A boost pedal does one simple thing brilliantly — it makes your signal louder, stronger, and more alive. Whether you’re pushing a valve amp into natural breakup, lifting a solo above the band, or adding a touch more presence to your core tone, a clean boost gives you extra headroom without changing your character.

Use it at the front of your chain to drive other pedals harder, or after your gain stages to raise volume without adding distortion. Subtle or powerful, transparent or slightly coloured, a boost is one of the most useful tools on any pedalboard — small box, big difference.

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.

New

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

noise gate

A noise gate pedal keeps your rig tight and controlled by cutting unwanted hiss and hum when you’re not playing. High-gain setups, stacked pedals, and long signal chains can introduce background noise — a noise gate steps in to silence it cleanly, letting your riffs start and stop with precision.

Use it to sharpen heavy rhythm parts, tame buzzing single-coils, or clean up complex pedalboards without sacrificing sustain. Dial it subtle for transparent control or tighter for that sharp, percussive stop-start effect — either way, it keeps your sound focused and professional.

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.
