the last 2 sets I bought of Swing bass have both had dead G's. I bought a set of Elites stadium (not as bright as Rotosounds but at least none of the strings are dead), and the guy in the shop says he replaces Rotosound single strings at the counter for dissatisfied customers- and they often have to do this- it seems that Rotosound know they have a quality control problem, but choose to replace strings after purchase rather than check them properly before they package them- a dead string feels different- the way it clatters against a surface is different- are rotosound just churning out strings so fast they can't be bothered to check them? the guy in the shop also said that rotosound had a particularly bad period when they used steel from china. in a Rotosound factory visit in Bassist magazine they said the original string winding machines were being run at double the speed now- I can't help thinking this is the root of the problem. another problem i've had is with the double ball end sets- the last 2 sets have had a string with an insufficient outer winding length to reach the zero fret, and I've had to wrap a piece of brass round the string at the ballend to move the string up.
