SETUP PREAMP INSTALLATION There is a second outer bezel included with your Prefix Premium preamp. The Prefix Premium will need to fit properly on many different shapes and sizes of guitars. It is for this reason we have included 2 choices of outer bezels. Choose the correct bezel to fit your instrument. If you have a very curved section between the waist and shoulder on your guitar, choose the pre-curved bezel. If you have a fairly straight surface to mount your preamp, choose the flat bezel. Choosing the correct bezel will ensure a proper fit when the preamp is installed. Remove the 2 pivot screws located on each side of the preamp bezel.
