I have an oscillation problem with my LTD MH-1000 w/ Evertune when using a low E string that is .059 or .060 gauge (D'Addario ATM). I tried going back downward to a .056 and the problem may be less pronounced there. Yet anything lower than .059 gauge does not work for me; I am tuned to D standard. Immediately after striking the E string (on any fret), the note is moving back and forth in an unusual way, an over-pronounced oscillation that kills my single notes and power chords. I've tried several strings and I've lowered the pickups into the body to no avail. This guitar did not exhibit this problem when using it at E standard tuning with a set of D'Addario 10-46; rather the guitar was superb in E standard, probably the best guitar I've ever owned until tuning it to D standard with heavier strings. Has anyone experienced this kind of oscillation problem, probably with heavier string(s) (heavier E string anyway) and perhaps using the Evertune bridge (6-string)? With a non-Evertune guitar and heavier strings? Any insight/advice? Heavy core strings? Find another guitar? Replace Evertune parts? Other?
