I only installed these strings to my new Hofner yesterday, so I can't comment on how they might sound once they've been "broken in", but from the first moment of putting them onto the guitar, the improvement in tone has been clear! My guitar's factory strings sounded too weak, muddy and unreliable in tuning when connected to an amp - since changing to the DRs, the sound and playability has improved massively. There's clearly a reason why DR are considered so highly among electric guitarists!
