Thanks for the quick replies, I was starting to get a bit worried as I have spent nearly £400.00 in the last 2 weeks on this stuff and I think my wife would kill me if I spent anymore.
As far as upgrading goes, I have seen some posts about pre-amps. If I bought a pre-amp do I use it instead of the battery box or as well as the battery box.
I will mostly be recording loud rock concerts, if I started using a pre-amp would I notice much of an improvement in the sound quality of the final recording?
