Adding this tuner to your guitar requires setting up the instrument to maintain professional performance. You can install it by yourself if you have the skills. Everything you need to install the system is supplied, except for the screwdriver needed to remove your existing machine heads. The RoboHeads don’t even need to be attached by woodscrews, as they are held in place by holes in the electronic plate. If you feel and feel uncomfortable we recommend to have this done by a qualified luthier.
