I got this from Rondo Music after seeing favorable reviews. However, it seems to be off. It came with flatwounds. It sounded atrocious, so I scrapped those and got a set of Fender nickel rounds. There was improvement, but the volume between the strings is uneven. The E and A strings are louder than the others, while the B string is very weak. The B string also just generally sounds crappy. Could anybody help me resolve these issues?
