Compressing the legendary footprint of MXR’s vintage studio rack unit into a pedalboard-friendly stompbox, the MXR Flanger/Doubler utilizes authentic bucket-brigade device (BBD) circuitry to deliver real, analog motion. Bridging the gap between sweeping, jet-engine flanging and thickened, offset doubling, it provides a versatile analog architecture built for both guitar rigs and advanced studio routing.

The pedal’s dual-voice engine seamlessly transitions from subtle, chorus-like doubling to aggressive, jet-engine flanging via a dedicated button, while standard manual, width, speed, regen, and mix controls allow for dialing in everything from mellow shimmer to sharp metallic resonance. The addition of an invert switch for polarity shaping, real-time visual tracking LEDs, CV connectivity, and a rear-panel line-level input switch elevates it above a standard stompbox, turning a vintage studio staple into a remarkably flexible hybrid tool for both guitar rigs and modular synthesizer setups.

Here’s a look at the controls:

  • Doubler button – switches between sweeping flanging and thickened offset doubling;
  • Manual, Width, and Speed – shape the sweep rate, range, and center point;
  • Regen knob – controls feedback intensity (from mellow shimmer to metallic bite);
  • Mix knob – blends wet and dry signals.
  • Invert switch – reverses wet signal polarity for airy/hollow or punchy low-mid textures;
  • CV In/Out – jacks for external expression or modular/sequencer synchronization;
  • Input Level – switch optimized for hotter guitar or synth line levels.
