Behringer BM-18M Cluster Box
Behringer · pedal
The Behringer BM-18M Cluster Box is an all-analog modulation pedal modeled after the Moog Moogerfooger MF-108M Cluster Flux. A genuine Bucket Brigade Device chip drives three effect modes: Chorus (5ms to 50ms delay time), Flanger (0.6ms to 10ms), and Vibrato. The LFO features six waveform shapes (Sine, Triangle, Square, Ramp, Sawtooth, and Random Staircase). Controls include LFO Rate, LFO Amount, Delay Time, and a bipolar Feedback knob that highlights even or odd harmonics. Tap tempo via footswitch. Stereo outputs. CV and expression inputs for Feedback, Time, Rate, Mix, and LFO Amount. Reviewed by Synth Anatomy and ranzee.com as a modulation powerhouse.
What stands out
“Signal-chain interaction: stereo outputs enable true stereo modulation spread to two amplifiers; CV inputs for Rate, Mix, and LFO Amount allow integration with modular synthesizer systems for external modulation control”
— from the community notes
“Second strength: the bipolar feedback knob that shifts between emphasizing even and odd harmonics gives distinct flanger characters”
