The MXR MC406 CAE Buffer is your essential solution for keeping your guitar tone crisp and pure, no matter how complex your pedalboard setup. Designed in collaboration with Custom Audio Electronics, this compact buffer pedal restores and maintains the integrity of your signal, tackling the common issues of signal loss and tone degradation that can occur with long cable runs and multiple effects. With intuitive controls and rugged construction, the MC406 ensures your sound stays punchy and present from stage to studio.

Modern gigging musicians will appreciate the MC406’s flexible gain and tone-shaping options, including dedicated Hi and Lo Cut switches and an adjustable +6dB gain slider. Its low-noise circuitry guarantees whisper-quiet operation, while the steel housing is built to withstand the rigours of life on the road. Whether you’re looking to compensate for pedalboard signal loss, drive long cable runs, or simply keep your tone pristine, the MC406 delivers professional-grade performance in a pedalboard-friendly package.

Maintain Your Core Tone

With 1 MΩ input impedance and true hardwire relay bypass, the MC406 preserves the natural character of your instrument. It acts as a transparent buffer, so your sound remains consistent and clear, even with extensive pedal chains or long cables. If you’ve ever felt your tone go dull or lifeless, this pedal will bring it back to life.

Flexible Gain & Tone Shaping

The adjustable gain slider lets you boost your signal by up to +6dB, ideal for making up lost volume or pushing your amp just a little more. Hi and Lo Cut switches let you fine-tune your frequency response, cutting harsh highs or taming unwanted low-end rumble as needed. Each switch features an LED indicator for instant visual feedback on your settings.

Smart Pedalboard Integration

The MC406 is designed for easy integration into any setup. It features dual outputs: use OUTPUT 2 for your main effects chain, or OUTPUT 1 as a direct, unbuffered feed for a tuner, second amp, or separate effects loop. A pass-through 9-volt jack even lets you power additional pedals right from the buffer, minimising cable clutter on your board.

Built for the Road

Encased in a rugged steel housing, the MC406 is built to last. Its compact size ensures it fits comfortably on any pedalboard, while its low current draw means it works seamlessly with your existing 9V pedal power supply. No matter where you play, your tone is in safe hands with MXR’s renowned reliability.
