I use a Sadowsky MS5 as my main bass, and I am having some major difficulties with the strings: the strings loose all of their brightness and clarity after about a week of playing. I have tried several sets of Sadowsky Stainless steel strings, and one set of EBS steel strings. They both lost the clarity and brightness in about a week. I thought that the problem was caused by me putting the strings on wrond. I changes a couple of sets with advice from pro-players, but it didn't help. I try to wash my hands everytime I play, but it is not possible everytime. My bass teacher has had a set of DRs on his Fender for a long time, and they still have the clarity. So, is the problem in: a) the bass b) the strings c) the player Should I try a set of coated strings, eg. Elixirs?
