Using this Allparts SPHM-A neck is easy. First, if you're doing a custom build, decide whether you'll use the bolt-on or glued-in 'set' method for installation. Make sure to handle the neck carefully as it's made of quality mahogany with a rosewood fretboard. When it comes to tuning, since there are no tuning peg holes initially, you'll need to add your own pegs according to your preference. For adjusting the truss rod, you can do it at the headstock. As for maintenance, keep the neck in a dry and stable environment. Since it's unfinished, you might want to apply a suitable finish to protect it. Also, regularly check the frets and inlays for any signs of wear and tear. If you notice any issues, address them promptly to keep your guitar in top - notch condition.
