Combining two distinctive overdrive and distortion circuits, the Keeley Blue Disorder 4-in-1 Blues Breaker and OCD Style Overdrive and Distortion Pedal gives you the power of four different drives into one stompbox. Featuring two switches, the Blues Disorder allows you to separate tone control from the clipping section for some juicy, unique, and experimental bluesy goodness.

Key Features

  • 4-In-1 – Loaded with 4 classic distortion and overdrive tones, you can combine 2 swappable Tone circuits to create 1 hybrid and experimentally unique soundscape.
  • Hybrid Blues – Combine aggressive hard-clipping distortion and smooth overdriven soft-clipping tones, for a bluesy and golden sound.
  • Authentically Analogue – For those searching for the right tone, with an authentic sound, then look no further than the Blues Disorder that encapsulates it all.

Flavoursome Tone

By mixing and matching the Tone and Drive switches, you can create a hybrid between the two circuits. The BB circuit is a low-gain smooth, soft-clipping overdrive circuit. Whereas the OC Circuit produces a hard-clipping OC distortion, giving you the best of both worlds. This presents you with familiar and sought-after tones, whilst opening you up to new and exciting sonic realms.

Diode Clipping

Loaded with both styles of clipping, the Blue Disorder can be used to create hard clipping distortion tones or smooth overdrive BB-style sounds. You can produce more aggressive and sharp distortion when the OC switch is enabled, or you can capture a soft clipping when the BB switch is engaged, for a sweet, crystal-clear sound.

Specifications

  • Power: 9V DC PSU (Adapter Not Included)
  • Controls: Tone Knob, Drive Knob, Level Knob, 2x OC/BB Switches
  • True/Buffered Bypass
  • Soft-Touch Switch

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.

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.

used

Used pedals bring character, value, and often a bit of history to your board. Whether it’s a well-loved classic or a recent release looking for its next home, a used pedal offers the same core tone at a more accessible price. Fully tested and described clearly, it’s a chance to grab great gear without paying brand-new money.

Go used to explore different sounds, track down discontinued favourites, or build your setup more affordably. Sometimes a pedal with a few marks on the casing still delivers flawless tone — and might even have a story or two behind it.
