I just put on Fender 9050 (M) flatwound strings (stainless) on my MIA Jazz fretless and had to lower my bridge to the lowest position AND adjust the neck relief a lot. This in order to make it playable at all. The strings that were mounted before were some flat black nylon coated set of unknown origin, although fender is not a bad guess. Anyway these black strings were a lot softer to play, not that stiff, or high tensioned that is. The gauge seem to be the about the same. Now my question is actually simple: Are stainless steel strings stiffer, or higher tension at the same gauge than nickels? Perhaps if I wanted stainless with the same feel as nickels I should go with one size lighter gauge, to compensate for this "stiffness" caused by the higher tension? I have always used nickels before by the way. Anyone?
