Hi everyone, I have a DJ mixer that I’m attaching a photo of. I wanted to ask if it’s worth sending it in for a full service—things like replacing some faulty knobs, replacing a few faders, or if a thorough cleaning and maintenance would be enough. I know some of the knobs are bad—like the master knob—and there are some issues with the audio card, where one channel is quieter than the other. So I wanted to know if it’s possible to get this fixed and if it’s worth doing, considering it’s a piece of gear I think is over 10 years old. Help for one of my oldest mates. 
Btw I’m actually in Florida any recommendations? Or is it gonna be better for some one than don’t know that much to find someone pieces and try to put together by myself?
That’s an MC6000mk2 so it’s always worth getting it fully repaired - it’s a great unit and built like a tank.
