These necks are easy to use and super cool. They save me way more time then a body through bolt on neck and having to cut the perfect neck pocket.
Please note that I do take the time to brace the inside. I suggest not only do you glue a wood brace along the inside wall on the side you’re bolting the neck to but you add two screws to the back of box screwing the back into that brace, this will help with action, loosen truss rod, file nut slots, some bridges I’ve noticed require less or more shim under the fretboard where it sits on the body, also I add a rib brace to the center and screw/glue it to stop any top box bowing, as well as bracing under the bridge.
