FYI: Your Kahler must be "Auto-Latch ready" in order for the Auto-Latch to work. How can you tell if your model will accept the Auto-Latch system? Simply remove the spring cavity on the back of the guitar and see if the spring block has a split in the center. If so, it's Auto-Latch ready. The Auto-Latch comes complete with everything you need to install it yourself. To get a better handle on the setup, see the Kahler Auto Latch setup instructions at the downloads link at the top of the page.
