New member to the Forum.Any Gibson "TB" IV owners?

[bridoyle]

I have recently took deliverly of a Gibson Thunderbird IV,Vintage Sunburst. Have owned it for a month and found it to be well crafted with 9 ply mahogany,rosewood neck. Replace the stock strings with ernie ball med.cromes.I would like to know the correct way of truss rod and bridge 3 way adjustment.No response from Gibson Tech Line.The owner's manuel gives little infor twards the basses.I will seek a luither if need be.
