GFISYSTEM ROSSIE FILTER Selling to organize my equipment. I think it's a filter-type effector that's easy to create sounds and easy to use. Body only. Used only indoors, in beautiful condition. Thank you. 【Multi-function Effector】 The ROSSIE FILTER is an effector that can add a variety of filter effects to guitar playing. You can freely adjust the tone using the PARAM, RANGE, MIX, and MODES knobs. 【High Operability】 The ENGAGE/RAMP, A/B, and TAP switches allow for instant effect switching. It is ideal for live performances and studio recordings. 【Durability and Design】 The orange body is highly visible, and the non-slip material on the bottom provides stable placement. - Brand: GFISYSTEM - Model Name: ROSSIE FILTER - Color: Orange - Control Knobs: PARAM, RANGE, MIX, MODES - Switches: ENGAGE/RAMP, A/B, TAP - Bottom: Non-slip material - Logo: GFISYSTEM Thank you for viewing.
