If the Virtual Guitarist 2 (VG 2) is not available in Logic Pro (and if it´s also not listed in the AU-manager) please follow this procedure to reactivate the VG2:
- Please delete every VG2 component from your system, exept for the content. Use the Mac OS X search function for this.
- Afterwards reinstall VG2 with the Virtual Guitarist 2 Universal Binary Installer (Only install the downloaded Intel version!)
- Trash the "AudioUnits-cache":
*user*/library/caches/com.apple.audiounits.cache - Trash the "Logic-cache":
*user*/library/caches/Logic/ - Now reboot your system.
