Midi Fighter Pro problem (?)

Midi Fighter Pro problem (?)

I bought few days ago a Midi Fighter Cue Master, obviously used because DJTT stopped the productions of MF pro.
I fell that the faders are very soft to move (I also have a Pioneer Ergo and the faders are so strong if compared to MF pro). I also see that the two knobs moves a little (very few) right n’ left if you try to move it to right or left, they are going to be brake?
Please answer me as soon as possible. :slight_smile:
Excuse me for my bad english but I’m italian. :open_mouth:
Thanks. :thinking:
