    What Do GFI Systems Say?

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

    • ​Envelope Filter - a colorful 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 sweepable 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 effects is imparted on your guitar or bass signal.
