The Spectrum Intelligent Filter is the most powerful stereo filter effect pedal ever created. Building on almost 15 years of filter pedal technology and know-how, Spectrum is the culmination of our finest envelope sounds and best thinking on how to easily incorporate those sounds into rigs of all types. The pedal not only features finely crafted envelope filter effects inspired by some of the most iconic and sought-after effects pedals on the market, it also includes buzzing, synth-like octave and distortion effects. The pedal is a cleverly integrated, all-in-one jam/funk machine. Whether you want to easily plug and play with its six carefully crafted factory sounds, browse the ever-growing Neuro library for additional sounds created by Source Audio and other Spectrum owners, or use the Neuro’s deep sound editing tools to create your own presets, this filter pedal will satisfy the needs of any bass or guitar player.

The Spectrum Intelligent Filter was designed with special attention given to the simple plug-and-play experience. Right out of the box the Spectrum offers easy access to tones inspired by some of the most iconic and difficult to find envelope filters effects pedals on the market. It also offers synth-like tones comprised of distorted octave and envelope phaser sounds. Because of the pedal’s ALT button, the Spectrum’s four knob control surface actually offers access to eight different parameters. Use the Spectrum’s Input Gain, Sensitivity and Speed controls to dial in the perfect envelope response for your needs. Maybe you like a slow and smooth envelope movement while you really dig-in on the strings, or possibly you want a quick moving filter that responds to light picking – either way is achievable with the Spectrum.​ The Frequency, Resonance, Depth and Mix controls provide fine control over the color and character of your filter effects. Whatever your needs, the Spectrum is the most comprehensive filter effects pedal available.
