Changes

* You have an artist whose part you want to record, but he is on a very tight schedule. You can get him in the studio, quickly set up a rig for him, and get him recording with a rudimentary tone. He records his part and leaves. You can then re-amp his playing for as long as you need to find the ideal tone, without requiring him to be physically present.

There are two common pieces of hardware associated with re-amping: a ''DI box'' and a ''re-amp box''. Some products feature both DI and re-amp capabilities.
