So I am getting ready for a wedding this weekend and just realized that one of my crew left the transmitter (body pack) for my G2 ew100 wireless setup at the last job. Now that there is the G3, no one carries the G2. Anyone have a suggestion on how I can get a replacement (frequency A). Thanks for any help.

A G3 transmitter will work with a G2 receiver, well as long as you stay on the frequencies that the G2 can receive (the G3 has more channels). In any case, hopefully you can get back your old unit...

Wouldn't FedEx overnight be cheaper than buying a new one?

G1, G2, G3 and 2000 series are all compatible with each other - providing you have the same frequency on both units.

Sorry, when I said they left it there, I mean it is gone. Thanks for the info on g1-g2-g3.
