Reviving an old post here, but wondering how the S4's are keeping up!
I just received mine last week, and after a week of use the Deck A & B knobs and faders feel broken in compared to deck C & D. This is of course expected with any piece of new hardware.
I've read about sticky buttons and the odd loose knob around the forums. Anything else I should look out for?
LOVING the S4. It's my first piece of DJ kit and just far too much fun!
Cheers!
