You normally use the RS66LD .045 .065 .080 .105 Strings but are wanting to use the Billy Sheehan Signature set .043 .065 .080 .110 and are wondering if it will buzz?
You can use this set for EADG tuning. You will just notice a "tighter" E string than with the .105 in the RS66LD. The .110 will also have a bigger tone than the .105.
The .043 G string will be a little snappier.
You shouldn't worry about any buzzing but as always a setup is recommended.
