Hey there.  One of the studs on my Ibanez's ZR trem has broken and I can't get it out.  The trem stud (the part to adjust the action) has cracked and can't be twisted to be taken out.  I have looked at IBANEZ RULES for the replacement parts and want to get it fixed.  However, I am curious if it's possible to fix and how much it will approximately cost.  I don't want to spend money on the parts just to be told it can't be done.

That's unfortunate.

take all the string tension off the bridge and try cutting a slot in the top of the broken off stud so you can remove it with a flathead screwdriver.
