I consulted with my other employer about wireless mikes, monitors, filters for speakers so they don't 'pop' when they talk, and wireless controllers. That was my shopping list(without the specifics but whoa be to those that didn't buy the right stuff)! He said the best part was that he could go out onto a protruding stage and still be clear sounding as opposed to dragging a lengthy cord for his guitar AND microphone!
I put together a list with prices and expedited shipping, got the purchase order approved, and placed the order. No more volunteering for me.
