On one of the Stairway mixes this particular vocalist had to re-do a section of the vocal and what I was provided from her sounds environmentally and tonally very different from the original vocal.

I was perusing ebay as one does and came across this http://www.ebay.com…

Its a usb powered and controlled recording punchlight.

Or does it just take a lot of practice? I recorded this guy last night and after he was done with his takes he would say, "i didn't like a couple bars in the bridge/chorus/whatever." I would go back and delete the section as clean as I could and then punch in record and punch out, but I had a lot of trouble getting some of it clean.
