An envelope filter that covers everything from legendary 70s gear to synth-like tones. The SPECTRUM INTELLIGENT FILTER is a filter pedal that not only offers rare filter effects rarely seen on the market, but also incorporates octave tones and distortion to create synthesizer-like tones. SOURCE AUDIO, which has earned a high reputation for its bass filters, has poured its extensive technology and experience into this pedal, enabling meticulous sound shaping that realizes the player's vision, from funky sounds to unconventional sounds. To allow for fine-tuning even with just the unit itself, four knobs provide access to eight different parameters. The INPUT, SENSITIVITY, and SPEED controls enable you to achieve the perfect envelope response to suit your needs, while the FREQUENCY, RESONANCE, DEPTH, and MIX controls allow you to control the filter's color and characteristics. Six factory presets are included right out of the box, making it ready to use on stage or in the recording studio.
