Behringer BM-18M Cluster Box

Well-modulated sounds for the analog cuddle session

With the BM-18M Cluster Box, Behringer presents a clone of the Moog MF-108M Cluster Flux from the popular MoogerFooger series. Behringer has succeeded in faithfully reproducing the special sound of the classic in all its details.
The BM-18M is an analog chorus and flanger effect with a particularly lively and warm sound. The circuit is based on Bucket Brigade Device (BBD) technology, a series circuit consisting of capacitors and transistors that delay an audio signal in small steps by passing charges from one capacitor to the next, similar to a bucket brigade. The large toggle switch is used to switch between two bucket brigades of different lengths, resulting in the two effects chorus and flanger. Both effects sound very good and have their own specific characteristics, which come to the fore even more at higher Feedback.
Things get really exciting when you add the clock-synchronizable LFO, which modulates the TIME parameter. Its six waveformsproduce effect variations that many guitar pedals have to match. Typical results are achieved with the sine and triangle waveforms. Square has a more switching character. Sawtooth and ramp provide rising or falling modulation curves. Stepped Random should appeal primarily to experimental musicians who consciously allow for random sound shifts.
The input stage is designed for line and guitar levels and can be overdriven, in most cases this sounds very musical and has a harmonic character.
