Microphone into Flashback X4 into bass amp+cab?

[1976fenderhead]

Hey, probably a stupid question but I got a Flashback X4 and was thinking of, for the looper, plugging a mic into it to record some vocal beatbox loops and then plug the bass in and play over them. Since the mic signal is different level from the bass's, could I cause any damage to the pedal and/or my amp and cab?

Nope!
