Strings can be a big part of how the instrument feels, and I am not usually inclined to be a cheapskate when buying them. However, these play as well as other brand strings and really do not cost as much.
Some corners may have been cut, but in the end they just play quite well. I find the tension might be a little lower?and to be perfectly honest, it seems to me that they might be ever-so-slightly thinner than other strings of the same gauge (as advertised on the pack).
This is in no way a deal breaker, though. I mostly install them on my cheaper basses, but now I have a set on a nicer Jazz Bass and they play very well.
They seem to have a very decent lifespan. Perhaps they are not quite as bright as other brands when new, but they do keep their brightness for quite a while.
In conclusion, these are nice strings, could go well on any bass, really, and at this point my only complaint is that they do not do any six string version, which would be nice as nowadays I mainly play a sixer. Other than that, I highly recommend them.
