The GFI System - ROSSIE Filter has the quintessential filter algorithms in a small and easy-to-use digital package. The intuitive interface coupled with the LCD screen lets the user easily control some great sounding delays. Stereo or mono In/Out available with the correct TRS adaptors. An optional external expression control can be added to on the fly control the delay parameters. As always, great stuff from the crew at GFI Systems.

From GFI: 

Rossie is a dynamic multi-filter pedal, encompassing 3 essential tone-enriching filter effects:

  • Envelope Filter - a colourful resonant filter that follows your picking dynamics.
  • Step Filter - a groovy, arpeggiated filter with fully adjustable steps.
  • Manual Filter - great for static tone shaping or sweep-able wah-like effect using an expression pedal.

Each filter mode offers 4 filter types: lowpass, bandpass, highpass, and peaking. Sweep range and resonance width are also adjustable. And on top of all of these, a dedicated Mix knob allows blending of wet and dry signal, this gives you total control of how much filtering effect is imparted on your guitar or bass signal.
