As a fanatic about Bass strings, this thread is good to see
Some very good points have been made. I think people need to be careful about what a 'factory' string is. They are still a 'brand' name string, that the manufacturer of the instrument has decided to use, because of many reasons. Budget obviously being one. I think it also depends on the quality of the instrument, and also, the players' taste. I think some of us are a little hasty in saying that .. the stock strings 'suck'. As some folks have already mention, it really is a matter of taste... These comments usually come from, with due respect, inexperienced players. Perhaps they feel a string that is a little raspy under their fingers, and decide that it's just a crappy string, not realising that they simply may prefer the smoothness of nickel, so on and so forth.
We are very fortunate that these days, the quality of pretty much everything, is pretty good. However, that is not to say that dud strings and string sets don't occur. I've been a fanatic about strings from the start. It's our very first connection with the instrument, they are the medium in which we extract tones from the wood, which is our bass! Not to digress too much, but I've found that Low B, and E strings with certain companies, are notorious for being dull, and lifeless, straight out of the package. It happens.
In summary, yes, there are 'cheap' strings.. though in my experience, pretty much every bass, no matter what price range, has a brand name string on it. I'm personally not aware of a company that just makes 'stock' strings and just churns them out. One last thing.. often strings that have been on basses sitting in music stores, may just have been dulled out from many fingers playing them. Strings don't just die from hours of bass playing and abuse, there are metal... they are prone to corrosion over time, this is something to consider also.
Hope this helps somewhat
