With the BM-13 Phaser, Behringer presents a clone of the Moog MF-103 Phaser from the popular MoogerFooger series. The BM-13 is an analog phaser effect with an incredibly dense, wafting basic sound. Operation is extremely simple, as there is exactly one control element per function and of course no submenus. It starts with the audio input, which accepts guitar and line signals and can musically distort the signal. The phaser part offers a choice of 6 or 12 filter stages and is sufficiently adjustable with the Sweep and Resonance parameters. An LFO with triangle waveform is integrated to give the effect its floating character. The basic speed can be switched between a very comfortable 0.01-2.5 Hz and a whirling 1-250 Hz. The modulation intensity ranges from nothing to moderate to "kill"; in short, the phaser pedal covers a wide range of sounds from slightly coloring to extreme settings and sounds consistently excellent. If you add control voltages from a step sequencer, a gated S&H or a function generator, the BM-13 could almost pass as an instrument in its own right.
The connections are the same as on the original: there are four CV/expression inputs for the Sweep, Reso,
