Source Audio Spectrum Intelligent Filter

The Source Audio 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 Source Audio’s top envelope sounds and their best thinking on how to deliver those sounds to any rig. The pedal not only features envelope filter effects inspired by the most iconic and sought-after effects pedals on the market, it also includes the option of octave tones and distortion, making Spectrum 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.
