"Conventional floor-type multi-effect processors are designed to sound good when they are plugged into a guitar amp. Modeling processors are designed for recording in line. Until now, there was no product that could handle both scenarios with equal finesse.  Introducing The G Series from Zoom. Each G Series Pedal offers two algorithms: One for live and one for recording. The sound you created at practice or in the studio can now be brought straight to the stage. Or take the sounds you worked out during a rehearsal and apply them seamlessly in the recording studio. Your creative scope has suddenly doubled."
