to use when shimming.

I've got some wood veneer I could use but I may have to double up. I'm needing some extra height to bring the neck up as my bridge is about maxed out.

BUT, would metal be better for transferring vibration?

Also, if I were to JB Weld the shim to the neck pocket, would that help with maintaining a solid connection(less energy loss due to maximized surface area)?

Hope I explained that well enough.
