I'm going to have a go at making my own Corda Cross-1. I don't know whether my rotary switches need to be break-before-make or make-before-break, or if it even matters! Can anyone help?

It matters: Do you want to short the signal or not?
Volume control: MbB
Source control: BbM

Thanks! Looks like I want BbM for the crossfeed level switch and MbB for the treble/bass adjustors.
