DDJ SB2 Crossfader replacement

Hi everyone,

I'm trying to figure out if the SB2 can take 3rd party crossfaders.  More specifically the innofader mini.  

The innofader page states that it supports controllers like the SR, which is mildly similar to the SB.  

Maybe one of you Pioneer pros knows if the SB2's crossfader is built into the board or totally swappable. 

Thanks,

Acts1
