are there certain gauge or types/manufacturers that are best for dropping the low E to D ? I have on Ernie Ball chrome plated flatwounds - nice and smooth feel - on a P-bass but they are Group III with the .100" E and it is way floppy when I tried drop D this weekend. maybe if the string had more tension to begin with or the gauge was different? any advice will be greatly appreciated to get me farther along before the experimenting with gauge etc. Thanks.
