Got it in a bulk purchase from a local dealer who was doing a huge clearance sale.

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 Source Audio's 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/distortion/filter effects. The pedal is a cleverly integrated, all-in-one funk/psych/electronic/jam 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 highly personalized presets, this filter pedal will satisfy the needs of any guitar, bass, keyboard, horn, or (insert your instrument here) player.
