question about unlocking items, upgrades, and customization

If I find a weapon, that "unlocks" an item for me, and then add a weapon upgrade to it, is it still possible for me to salvage the item I've unlocked?
For example, I find a bow that unlocks an ebon bow string. I upgrade the bow. I later salvage it... Do I still have a chance of getting the bow string? Is this probability any different from the probability before upgrading? (assume my upgrade does not replace the ebon string)
Also, if I customize a weapon, is it possible to still salvage the unlocked item, and is the probability the same?

Yes it is posible... all though you could just get the other upgrade that you added or use crafting mat.

from what i have read you can take an item with multiple upgrades and expert salvage it but you will get only 1 of the upgrades back and even that is not guaranteed

Just make sure that you don't upgrade with a different bow string You have a chance to salvage either of the upgrades currently on an item.

I've heard claims that it's possible to salvage upgrades, but I've never seen it happen.

Ok, thanks for the replies all.
