GFI System Rossie

GFI System Rossie is a dynamic multi-filter peda with 3 tone-enriching filter effects: envelope, step and manual filter, each with 4 types.
​
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.
