I've got an MIM Fender Standard Jazz strung with DR nickel Lo-Riders. When I pluck or slap the low E string, it's got lots of "thump" and bottom end, it sounds awesome. But when I do the same to the A string, the sound just isn't there. I slap the A string and it sounds weak. Also seems like there's lower output for that string. The strings are standard gauge, 45-105. I did a search for this problem and didn't find any threads pertaining to it. Anyone know how to fix this? I don't think it's the strings, as I had some Rotosounds on it previously and it did the same thing.
