This post got me curious. I just put fresh SCGC lows on my two 00s so I played the 2nd fret A note to see if it sounded weird to me. Seems perfectly normal on my two guitars. I have had experiences where certain brands of strings don’t sound good on one guitar but sound great on another. For example: I like John Pearse PBs on Gibson acoustics but they made my Martin 00-28 sound dead.
