I own a LTD F414FM(4 string) & my band plays using drop a tuning plus in the area I live they only got d'addarios & ernie balls so that limits my choices. I tried .135 d'addarios & it was not really that good so what should I try next for drop a, .125 or 130?? 
The .135 gave out a really dull sound & used to touch the fret board even though the setup was adjusted.
