Behringer BM-18M CLUSTER BOX Analogue Chorus Flanger Pedal

Analogue modulation with deep routing and tempo control

The Behringer BM-18M Cluster Box combines chorus, flanger and vibrato into a single analogue modulation platform with extended control. A range rocker switches between lush chorus textures and sweeping flanger tones, while vibrato-style pitch movement can be dialled in through modulation depth and delay shaping. Drive and Output Level controls introduce analogue-style saturation, allowing the effect to add harmonic weight rather than simply modulation.

An LFO section with six selectable wave shapes governs Rate, Amount, Delay and Feedback, making it possible to move from smooth shimmer to aggressive, resonant sweeps. Tap tempo keeps modulation locked to performance tempo, which is especially useful for rhythmic flange or pulsing chorus textures. A Blend control balances dry and effected signal for subtle thickening or fully immersive modulation.

Extended routing includes CV, MIDI and expression control, plus a feedback insert loop for further signal processing. Stereo outputs and USB-C integration expand flexibility for pedalboard, synth or studio use.

At Riffs & Licks Music, we think the Cluster Box is ideal for players who want classic analogue chorus and flanger tones with expanded control and routing options, particularly those integrating modulation into tempo-based or modular-style setups.
