The Aclam Dr Robert Overdrive Pedal is the ultimate evolution of a classic, trusted by renowned artists and featured on countless pedalboards since its debut in 2019. Now in its third version, the Dr Robert V3 refines every aspect of its design to deliver unparalleled versatility and tone. This pedal captures the essence of the legendary UL730 amplifier’s EL84 power stage, offering rich, dynamic overdrive that responds beautifully to your playing style. Whether you seek crisp cleans or saturated distortion, the Dr Robert V3 adapts effortlessly to your needs, making it a must-have for players who demand both character and precision.

What sets the Dr Robert V3 apart is its enhanced control layout and improved circuitry. The addition of Bass and Treble controls beneath the Mids knob completes the full UL730 tone stack, allowing you to sculpt your sound with greater accuracy. The Mach Schau! gain control, now a fully adjustable potentiometer, offers a wide gain range from subtle warmth to thick, creamy saturation. Meanwhile, the redesigned FET section and new LO/HI gain modes provide flexible gain structures perfect for any guitar or pickup type. The pedal also features a low-impedance buffered output, ensuring your tone remains clear and consistent even with long cable runs or complex pedal chains.

With all internal controls brought to the surface, the Dr Robert V3 unlocks the full potential of its circuit while showcasing the stunning Klaus Voormann artwork that adorns its enclosure. Tap both footswitches simultaneously to switch between LO GAIN mode for cleaner tones and HI GAIN mode for the classic Dr Robert overdrive roar. This pedal is the definitive version of Aclam’s flagship, combining superior tone shaping, improved response, and rugged reliability to inspire your playing for years to come.

Complete UL730 Tone Stack

The inclusion of Bass and Treble controls alongside the Mids knob offers full access to the legendary UL730 amplifier tone stack, allowing you to fine-tune your sound with precision and achieve a wide palette of tonal colours.

Expanded Mach Schau! Gain Control

Replacing the old internal trimmer with an external potentiometer, the Mach Schau! gain control provides a broad range of saturation levels, from nearly transparent boost to rich, creamy overdrive, giving you dynamic control over your distortion.

LO/HI Gain Modes

Switch between LO GAIN mode for crisp, clean tones suited to high-output pickups, and HI GAIN mode for the classic saturated Dr Robert sound by simply tapping both footswitches, offering versatility at your feet.

Improved Buffered Output

With output impedance reduced from 50kΩ to just 3kΩ, the Dr Robert V3 maintains tonal integrity over long cable runs and remains unaffected by the pedals that follow, ensuring your sound stays clear and punchy.

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.

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.
