Hello Updown,
Wow, that V sounds like it's going to be beautiful. Are you posting any pics in the 'work in progress' section? ??? You'd better!! I also think it's really cool you're using a maple neck like I did. It is very rare and it really looks sharp. Triple Shots too? Sweet. Mine work perfectly.
About the non slip pad. No, I did not put one on my V. I've seen them on Gibsons, but have never had the opportunity to sit down and try one. I did not want to "obstruct" any of the beauty of the woods and finish I chose for the guitar, so I did not even consider one. That said however, I quickly discovered I would need to wear a strap every time I played it. That system works great and keeps the V exactly where I want it. Be very 'selective' when you decide where to drill the hole for your strap to attach to. The farther out toward the back of the 'wing' you go, the more angle the neck has as it hangs on your shoulder. Get it where you want it! If you want the neck to be more parallel with the floor, move the button toward the body . . . for a more 'upward angled' neck, move the button out toward the tip of the wing. Good luck! Now let's see some pics!!! :rock-on:
