Hey,
I am using an RG7321 tuned to Drop A (AEADGBE), and at the moment the high 6 strings are d'addario 10-46 and the 7th string is a 0.060. Now, I calculated the string tensions based on the individual lenghts of the strings, and found out my Low A has about 2kg less tension on it than the rest. It does feel a bit more floppy aswell.
So I am planning to put on D'Addario 0.011 - 0.049 and a 0.070 for the low A, as i like the feeling of about 8-9kgs of tension (i tuned my guitar up some steps to check it out). The low A would have about 8kg of tension on it, pretty much the same as the other strings.
Nevertheless, I am concerned about warping my neck sideways. I am aware I'll have to adjust the
truss rod and most likely intonation, but the way my guitar is set up right now, when looking down the edges of the neck it seems like it is more bent on the side of the 7th string than on the side of the high E. This might be an optical illusion and the guitar just plays fine right now, but maybe having even more tension on the low A will make this worse.
Am I about to destroy my guitar?
