The Radial X-Amp is a 500 series module that lets you take a pre-recorded guitar track and send it back to amplifiers and effects so that you can tailor the sound to suit. The advantages of Reampingª are many: when recording, the guitarist need only concentrate on the performance. Working out specific sounds and optimal mic placement can be done later. This eliminates hours of tiresome repetition while allowing the producer to adjust the character of the track as the production evolves.
