Simple out of the box, deep under the hood

Out of the box, the Spectrum Intelligent Filter was designed to deliver an effortless plug-and-play experience with instant access to sounds inspired by some of the most rare and iconic envelope filter FX pedals. But Spectrum also goes deeper with an arsenal of jaw-dropping synth-like distorted octave and envelope phaser sounds. The pedal's ALT button turns Spectrum's 4-knob layout into eight distinct parameter controls.

Dial in the perfect envelope response via Spectrum's Input Gain, Sensitivity, and Speed controls. Want slow, smooth envelope movement while you dig into the strings? Or perhaps a fast-modulating filter that responds quickly to light picking — Spectrum does it all. The Frequency, Resonance, Depth, and Mix controls give you fine control over the color and character of your filter effects.
