My noobie question is, is it worth using the Radio Shack Volume Attenuator if I'm recording live music at an outdoor venue as opposed to an arena or club? I'm on a limited budget right now and Bike Week is just around the corner. One of the Harley dealerships here in Florida has a lot of good acts playing for free. My stealth rig right now consists of: SP-BMC-2 > Sony MZ-RH910(mic in). Any input will be greatly appreciated.
