Gfi system Rossie Filter

GFI SYSTEM Rossie Filter 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.
