Hey, i currently have 9-46 on my les paul, i used to have 11's on it. But now i feel like i want 11's again, but the tech changed my strings when i brought it in service. Do i need to lower or raise the TOM bridge?
If anything you'd need to raise it until you don't have any fret buzz. Also use the truss rod after the strings have been on for a couple of days to sort any unwanted bow.
i dont think you would need to raise the action if your going up in gauges.
