I'm never going to do a neck reset. At least I hope not.I watch a lot of youtube videos ,of people doing resets.It's really very interesting.They remove the fret where the dove tail should be,then after drilling a hole through the fret slot they inject steam .That loosens the glue joint around the dovetail. It can take a while. No one ever says this,but I can see you also loosening the glue joint at the neck block.Now you got a real problem. These guys doing this are luthiers, I'm not by any means. Thats a job for the pros .
