I have been lurking on these forums for quite a while now, and I've gotten pretty good at live recording. I have a sony MZ-NF810 recorder, SP-BMC2 mics and I had been using a sound pro battery box....until 2 days ago. I finally decided to test out the Radio Shack attenuator (It was te first time Ive gotten to record a band that I'm not really in to). Definitly got my best recording ever last night using it. I recorded another show today (Vertical Horizon, 3EB, and the Pat Mcgee band)...The recordings all came out fantastic. Its amazing that a $6 part can do the job better than a $50 one. Needless to say, I have no use for the battery box anymore. Thanks for all the advice.
