Jem Jr WN 2004 Neck Stability?
i have a jem jr 2004 with an ILT 1 trem. i remove the trem system and changed it to traditional trem from aldridge empire. it's duralumin saddles and block. a day after my luthier finished his job, i rock this beauty, sound and feel great. the second day, i remove the pups (duncan designed) and changed it to modded tone zone. sound way more beautiful than before. it's perfect. but the third day i strung it, i shocked. the action is bit higher than before, and the tuning slightly dropped to nearly E flat. i checked the rosewood block join, and it's fine.
my question is:
1. is it a natural habit of a new string?
2. is my neck stability is awful?
3. another answer?
i need your opinion.
thanks and regards...
