Titebond (website) says 24 hours for items under stress, and I think 1 hour minimum for non-stressed joints. A neck joint is definitely stressed, so 24 hours.

Yes, you can clamp too tightly if you manage to squeeze out almost all the glue (or so I’ve read/watched), but Titebond themselves have joint strength tables that show increased strength with increased clamping pressure. They go up to 100psi IIRC. So I’d clamp up pretty tight, just not excessively so. Your typical ratchet bar clamp won’t be able to overdo the pressure, and a G-clamp will struggle unless you’re really strong and go mad on the tightening or fit a tube over the handle for more leverage.
