Re: RG1550 neck pocket.
Hi again Michelle. It's Ok to leave it with nothing in the gap. A tight neck pocket is what causes neck joint cracks. If you have good string alignment and good string spacing, then leave the gap alone (unfilled). just keep the neck screws nice and tight. They are more than enough to keep the neck in place.
Keep an eye on the neck and gap as your weather changes to warmer temps and humidities go up. the gap may shrink some if you keep windows open during the day.
