Behringer BM-18M CLUSTER BOX: Modulation Muscle in a Compact Chassis

The CLUSTER BOX’s LFO section is where things get truly interesting. Users can select from a range of LFO wave shapes, including square and random stepped, to dramatically alter the modulation character. Rate control is accessible via a knob or tap tempo, making it easy to sync with a performance or external gear.

The video demonstrates how the square wave can introduce abrupt, dramatic changes, while the random stepped wave injects a lively, glitchy quality into the modulation. This breadth of LFO options elevates the pedal beyond traditional chorus/flanger fare, offering sound designers a toolkit for everything from smooth sweeps to unpredictable textures.

Editorially, it’s clear that Behringer wants this pedal to be more than a one-trick pony. The LFO flexibility means the CLUSTER BOX can serve as a modulation hub, capable of everything from classic ensemble effects to experimental, modular-inspired patches.

Integration is a major theme, with the BM-18M offering both CV and MIDI control. The rear panel bristles with connectivity, allowing users to patch in control voltages or expression pedals to modulate parameters in real time. The video shows the Neutron synth’s envelope and LFO outputs controlling the CLUSTER BOX’s mix and time parameters, demonstrating the pedal’s flexibility in a modular or hybrid setup.

MIDI support is equally deep, enabling LFO sync to MIDI clock and parameter control via CC messages. USB-C connectivity opens up further possibilities, including preset management and firmware updates through the Guitar Tribe app. For those who want to automate, sequence, or recall their favourite modulation settings, the BM-18M is clearly designed to play well in a modern, digitally connected rig.

The CLUSTER BOX’s stereo output is more than just a convenience—it’s a key part of its sonic arsenal. By default, the right output is inverted, creating a swirling, phase-shifted stereo image that can make a mono source sound enormous and immersive. This is a classic trick for modulation effects, and Behringer gives users the ability to fine-tune it under the hood.

Hidden inside the pedal are internal dip switches, allowing users to alter the stereo phase relationship or even split dry and wet signals across the outputs. This level of tweakability is rare in compact pedals and will appeal to those who want to tailor their stereo field for specific mixes or live setups.

In sum, the BM-18M CLUSTER BOX emerges as a modulation powerhouse, offering deep control, broad connectivity, and stereo versatility. Whether you’re after lush chorus, jet-plane flanging, or modular-style modulation mayhem, this box is engineered to deliver—and to invite a bit of patching mischief along the way.
