Multi Filter

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.
