Hey guys, I have an Ernie Ball MM SR5 which I tune ADGCF. Lately, The D (e) string has started to go dead almost immediatly. Actually it doesn't really go dead....it just doesn't sustain at all. The open string note is just a dull "thud" and dies off almost immediatly. This does not happen with the other strings. I thought originally it was just a side effect of the lower tuning on a 34" scale bass, but the problem does not occur with the A (B) string. The setup on this bass is average height, with very little neck relief. Intonation is perfect. I've tried a couple of different guages as well.....any advice.....???????
