So I am in a power metal band and am looking for a much heavier gauge of string for the heavy sound I'm looking for, think John Myung on Awake. So I emailed SIT strings and they said the thickest string they could make was .135, which I find odd, because they make a jauqo's C# which is a .195 soooo . with that limitation the string set is I'm thinking going to go a little like this. High C: .40 G: .55 D: .75 A: 100 E: 115 (maybe 120) Lo A: 135 (I really want a 145 but as I said, they said they couldn't be made.... which im still confused about.) I am currently playing a Yamaha TRB6p, which has an ebony board so I don't think cracking will be a problem. What do you think about these measurements?
