When the transmitter is docked in the receiver, the G10 will select the best RF channel from 14 possible channels.

Can multiple sets of base/bug work without stepping on each other?
Yes, but you gotta be careful:
- Connect Tx #1 to Rx #1—which chooses an optimal channel and syncs them—and then plug into guitar #1
- Connect Tx #2 to Rx #2—which chooses the second most optimal channel and syncs them—and then plug into guitar #2
If you don't do everything in the right order, there's a chance that the channels will swap—or worse, not work at all! If you're in the heat of a gig and you and another guitarist are swapping Txes in and out of Rxes, yes, there's a chance for bad things to happen. Luckily, the Tx's battery will last longer than the longest gig, so you shouldn't have to dock it until after the last encore.
Keep in mind that G10 was never meant to be a touring solution. It's most comfortable in living rooms, home studios, and practice spaces. The top goals were ease-of-use and sound quality (and affordability!), not multichannel flexibility.
G70's considerably more expensive, but it lets you connect up to 16 guitars/Txes to the same Rx and cycle instantly between them with a footswitch (and even route them to specific sets of outputs at specific levels with specific cable tone settings and specific LED colors).
