Source Audio Spectrum Intelligent Filter Pedal

Limitless sounds from one of the world's most innovative guitar pedal brands. Source Audio claim the Spectrum is one of the best envelope stompboxes ever - and we can't really argue. Sounds from the Spectrum stretch way beyond the confines of the small enclosure thanks to the MIDI controlled Neuro Editing System, letting you tweak to your hearts content or load up well over 100 presets. 

Settings include the ability to control panning, making the stereo nature of the Spectrum feel large and alive. And it goes way beyond your run-of-the-mill envelope, as you can add splashes of octave up and down, as well as synth electronic vibes. 

As with all Source Audio pedals, the Spectrum is made with extreme precision, quality digital components and works brilliantly if you just want to plug in and play right off the bat. This is one funky, groove-filled box of fun.

Here's what Source Audio say about the Spectrum:

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.
