As of now, Line 6 has discontinued production and support for its Gearbox Plug-In since its POD Farm Plug-In first appeared on store shelves and offered by online retailers in late 2008. However, its installation bundle still carries the default plug-in installer, which continues to work in existing installations that were registered with serial numbers acquired before October 2008. In the meantime, registered users of GuitarPort Online shall continue to receive backend support and updates for the licensed Gearbox 3.7 or higher installed in their PCs. Otherwise, new users must install the POD Farm plug-in with their Line 6 Gearbox and delete the default DLL files before launching the application in Windows and Mac OS. This digital modeler for amplifiers requires at least 512 MB system memory and up to 10 GB disk space to record music in raw form and edit their sound bites to produce a more solid guitar tone with additional distortion, delay, modulation, or filter effects.
