About the Product

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.

GFI System: ROSSIE Filter - WAH (Manual) Filter demo

GFI System: ROSSIE Filter - WAH (Manual) Filter demo

Global: Australia: GFI System's ROSSIE Filter features three types of filter - envelope, manual and step. Each type has six parameters you can tailor it with. Expression pedal and external tap tempo facilities are onboard as well as two recallable presets. The Rossie Filter is easy to use, sounds great and is a lot of fun. So if you want to get funky, get Rossie. This is my Manual as Wah Filter demo; basically an expression pedal controlled manual filter to sweep the frequency and create the wah effect. This video is sans chat to get the message across quickly and (hopefully) musically. Demos of the other Rossie filter types appear on this channel also.

GFI System Rossie Filter

GFI System Rossie Filter On Reverb: Next up in GFI Systems compact pedal lineup is the Rossie Filter. 3 different modes cover everything from funky envelope filter to synthy steps and manual eq or wah effects when using an expression pedal. All the essential controls are laid out for you along with a helpful visual from the screen. Like other GFI pedals, secondary functions are accessed by pushing and turning the knobs. Powerful controls give you the power to match the input sensitivity to your guitar or bass and tweak the quack with 4 filters: LP, BP, HP, and LP+HP. The Range also helps embellish the attack of the envelope or puts some extra emphasis on that arpeggiated step filter. Plus, it’s secondary parameter of Q width provides subtle vocal-like filters all the way to laser-like filter sweeps. The dry mix takes Rossie to a whole new level, giving your instrument back its full frequency range or allowing cocked wah or a rhythmic step filter to sit back in the mix for extra texture. GFI System also provides tap tempo with subdivisions and the same switch can toggle between your 2 favorite presets on the fly. Plus, you can control any of the 3 main parameters with an expression pedal or ramp them using the onboard footswitch for a multitude of frequency shaping tasks.
