Problem A: What model year is your VWH?? The proper trem angle depends on which Edge trem you have. Also, what gauge strings are you using?? If they are 009's then you shouldn't have had to mess with the springs unless they are way old.

Lastly, NO guitar stays in constant perfect pitch forever and ever!! Steel stretches and the high E, B and G are usually the first to go
IF you bought it new, leave the pups at factory level. If you bought it new, I'd recomend leaving the pups at factory setting. One of the biggest mistakes people make is raising the pups up to right under the strings

They don't need to be that close
