Discover the Spectrum Intelligent Filter

The Soundblox Pro Bass Envelope Filter evolved from the hugely popular Soundblox BEF. The Soundblox Pro BEF features 22 different envelope filter effects including 2 and 4 Pole Low Pass, Single Peak, Triple Peak, Peak/Notch, as well as Phaser effect engines. Each filter effect can be further modified with a variety of control options including a 7-band equalizer, positive/negative filter sweeps, sweep range, attack and decay speed settings, or frequency range selection.
Choose from four different modulation sources including classic envelope filters, selectable LFO wave forms with tap tempo, a passive expression pedal and the Hot Hand motion sensing ring. Use an external expression pedal to modulate filters like in a standard wah pedal or to control a wide variety of parameters including sweep range, effect selection, LFO speed and more. Like all Pro Series pedals, the BEF Pro features three footswitches with two banks that hold six customizable presets.
