SOURCE AUDIO SA248 SPECTRUM ENVELOPE FILTER

Envelope filters covering everything from legendary 70s synth-like tones

The SPECTRUM INTELLIGENT FILTER is a filter pedal that not only produces rare filter effects that are rarely seen on the market, but also creates synthesizer-like tones with its octave tone and distortion. SOURCE AUDIO, which has been highly acclaimed for its bass filters, has poured its extensive technology and experience into this pedal, allowing players to create precise sounds that can be imagined, from funky to quirky.

For fine-tuning, four knobs give access to eight different parameters: Input, Sensitivity, and Speed controls let you fine-tune the perfect envelope response to your needs, while Frequency, Resonance, Depth, and Mix controls control the filter color and character.

Six factory presets are included, ready to use on stage or in the studio. For deeper sound tweaking, connect to the Neuro Desktop Editor or Neuro Mobile App (free download for iOS and Android) for more detailed editing and access to presets created by users around the world.
