Hi, I encounted the worst nightmare of a dj: drink pouring into the gear. After this episode, my controller's motherboard was cleaned with isopropyl alcohol, but, unfortunaltely, one of the faders - the right channel - was affected (carbon fell is some parts and the contact is bad, resulting in fader bouncing without being touched). I've done some research to find the proper replacement, but my search ended with no answer. My question is: What fader replacement should I buy for my Z1? Is a standard fader for all NI gear? Thank you in advance.
