I got myself some new D'Addario ProSteels EPS 160, and while the 'closed' notes (so, while holding a fret) sound alright (the sound of brand new strings is not what I'm looking for), the open notes sound twangy and/or metallic like. So basically, the open A string sounds very different to the E5 note. Will this wear off or do I need to do some adjustments? I've searched the web but couldn't find anything useful. Thanks in advance!
