My guitar tech tells me that bass guitars tend to warp with the low string end twisting, because of their "higher tension". I've seem tension charts by TI & D'adario that indicate that even on balanced sets the higher strings, d, g & c tend to have higher tension. Should this raise a red flag about my tech's qualifications? He did do a good job leveling the frets of my Ibanez (which has two truss rods). I am modding my Squire DAVJ to accommodate another string (a c string) & I want to prevent this warpage/twisting phenomenon to occur. I had planned on using the following gauge DR Fatbeams: .130, .105, .85, .65. .45, .30. Now I am thinking that I should replace the .130 & .105 gauge Fat beams with .135 & .110 Hibeams to even out the tension. The .110 Hibeam sounds darn close to the .105 Fat beam. My .130 fat beam's dull, & lacks growly overtones anyway. Doesn't integrate well with the other strings. If the .135 Hi beam is too light I can EQ it. (Hi beam low b's do tend to emphasize overtones & growl @ the expense of the lowest 55HZ harmonic--all fundamentals are silent on bass guitars.) Am I on the right track, is this a good prophylactic measure to prevent twisting/warpage of my Squire neck that has only one truss rod. Or is my tech blowing smoke up my butt?
