For sale Aguilar Filter Twin (sound interference issue)

I have this cool Filter Twin effect pedal, I don’t use it in my home studio because unfortunately it gets some “radio frequency interference” it’s strange because my other pedals don’t get that interference, the pedal works but i have that issue with it.. i can’t say that you are not going to get that interference, the pedal works, but you get that little type of on and off feedback distorted sound,,,...maybe you can fix it or maybe it’s not gonna do that interference sound....you can have it for $64 shipped only CONUS, the chassis it’s in mint condition, I even have the box ,....
