Yep page numbers and a logo on each page - possibly in the header or footer would be a good idea. I'm pretty sure you can set that up in word so that it happens automatically.

Also, just noticed a typo or more likely autocorrect error: Last page "for guitars with floating bridges the same apples..." should probably read 'applies'.

I still haven't had time to have a detailed read through, but I really like the tone you've set and the information is terrific. I'm really busy for the next month or so, but I'm happy to help out with any extra diagrams or anything you might need.
