Sometimes saying something is rubbish it isn't just an opinion; it can be a quantifiably true statement.
As an example my newly acquired 'made in China' Modern player starcaster bass is a lovely instrument to play now that I've slung on a set of LaBella flats and set it up, however it came from the factory fitted with one of the flimsy cheapo output sockets that has a good chance of the tip connector losing its springiness over time and causing the signal to cut out at the worst possible moment. As the bass is around twelve years old, the original socket is surely on borrowed time. Whenever I encounter one of these it gets replaced with a switchcraft, or preferably a pure-tone socket, and the original goes straight into the bin.
Now that I have fitted the bass with a pure-tone socket, I can have complete faith that the output jack is top quality and won't fail on me.
new pure-tone socket on the left, crappy flimsy cheapo rubbish original socket on the right.
