GFI Rossie Filter

Unleash Your Sonic Creativity with the GFI Rossie Filter Pedal

The GFI Rossie Filter pedal is your gateway to a world of dynamic multi-filter effects, offering three essential tone-enhancing filter modes that will redefine your sound. Whether you're looking to infuse your music with expressive resonance, arpeggiated grooves, or static tone shaping, Rossie has you covered. Let's dive into the details of these remarkable filter effects.

Envelope Filter - Dynamic Resonance at Your Fingertips

The Envelope Filter in Rossie is a vibrant and resonant filter that reacts to your picking dynamics. It adds a burst of color and character to your playing, delivering expressive and dynamic filter sweeps that follow your every note. With adjustable filter types including lowpass, bandpass, highpass, and peaking, you can sculpt your tone precisely as you envision it. The sweep range and resonance width are also customizable, allowing you to craft the perfect envelope filter effect for your music.

Step Filter - Groove with Arpeggiated Precision

Step Filter mode introduces a groovy and arpeggiated filter effect that is fully adjustable. You have complete control over the filter steps, allowing you to create intricate and rhythmic filter patterns that sync perfectly with your music. This feature opens up a world of creative possibilities, making Rossie ideal for musicians who want to explore new sonic dimensions. With the same versatile filter types and adjustable parameters as the Envelope Filter, you can tailor your step filter sound to suit any genre or style.

Manual Filter - Shape Your Tone, Your Way

Rossie's Manual Filter mode provides versatility for both static tone shaping and a sweepable wah-like effect when using an expression pedal. It's a fantastic tool for fine-tuning your sound to perfection or adding a touch of expressive wah-wah flavor to your playing. Just like the other modes, you have access to a range of filter types, sweep options, and resonance controls. The dedicated Mix knob lets you blend the wet and dry signal, giving you precise control over the intensity of the filtering effect on your guitar or bass signal.
