Yes, the amp without the FBV work perfect. I haven't tried that, I will try it later today or tomorrow and tell you if it worked.

Hi there, I bought a spider iv 75 w and a mkii express 2 and a half years ago. Both have been working great till 2 months ago. Now, when I plug the mkii to the amp it make a wierd noise, kinda distorted/ fuzzy and kinda tremolo too. I think this may be 1 of 3: - cable is not good, which I already tried to change and nothing changed, so no; - amp port is not working good; or - mkii is not working good. The amp alone works fine. Can anyone help me with this? Have anyone had this problem? Thanks in advance.
