MXR M117R Flanger: Review

Encased in a durable metallic gray chassis, the M117R features four intuitive knobs: Manual, Width, Speed, and Regeneration. These controls allow precise shaping of the flanging effect, from gentle modulation to intense, spacey textures. The pedal operates on two 9V batteries or an 18V adapter, providing ample headroom for clean, dynamic effects. Its true bypass switching ensures your signal remains uncolored when the effect is disengaged. The M117R's design maintains the classic aesthetic while incorporating modern reliability.

Sound and Performance

The M117R excels in producing a wide spectrum of flanging effects. By adjusting the Width and Manual controls, users can achieve everything from subtle chorus-like shimmer to deep, resonant sweeps reminiscent of jet engines. The Regeneration knob adds feedback, intensifying the effect for more pronounced modulation. Notably, setting the Width to zero disengages the auto-sweep, allowing manual placement of the effect along the frequency spectrum—a feature that adds versatility for creative sound design.

User Feedback

Musicians praise the M117R for its rich, analog tone and versatility. Users highlight its ability to produce both classic and experimental sounds, making it suitable for various genres. Some note that, compared to the original M117, the newer version offers a more pronounced sweep, which can be advantageous for those seeking a more dramatic effect. However, a few users mention a slight volume drop when the effect is engaged, a common trait among vintage-style flangers.

Conclusion

The MXR M117R Flanger stands out as a faithful reissue that captures the essence of the original while offering modern enhancements. Its robust construction, versatile controls, and rich analog sound make it a valuable addition to any pedalboard. Whether you're aiming for subtle modulation or dramatic sweeps, the M117R delivers with authenticity and reliability.
