I bought a set of Roto 77's and the windings are very inconsistent between strings. The G and D are very smooth, then the A has barely more space between the windings, and the E has noticeably more space in the winding. This makes the E sound a little more like a roundwound string (especially when sliding), and I've also noticed it has lower output than the other strings, although this might be a sign that I need to adjust my pickups. Speaking of adjusting pickups, is it normal for the high strings to be much louder, even with both pickups unadjusted, or is this more of a technique issue? I tend to dig in on the strings and get a lot of fret clank, so it could just be that the G & D are much easier to pluck.
