Here's a pic for your enjoyment:

The guitar came in good condition, albeit with no tools, papers, G&L case etc. It plays wonderfully and I already love it.
I have two questions.
1] There is something missing from inside the saddle-lock bridge so I can not loosen the lock to adjust the saddles. I presume this is some kind of hex-nut that was loosened too much and lost at some point. Is there a simple / easy / inexpensive solution? Or, do I need a new bridge?
2] What are the recommended specs for pickup height and individual pole-piece adjustment?
Many thanks
