My late production Tacoma D-55 came with D'Addario PB mediums, as did her replacement NH 2014 D-55...not sure if those
were EXP...that guitar was set up so well by them I
thought they were lights!
Based only on the "rumour" that there was some collaboration between DR and Guild at some point, I tried DR's long ago and they are wonderful it seems on all my Guilds, especially that newer series that strat with "V" that I cannot bring to mind.
OTOH, neither my D-55 nor F-47 take to the monel/nickel compound strings at all...like putting electric flat wound strings on an acoustic! They are excellent on my Huss & Daltons but terrible on the Guilds...
Man up, git yer mediums on...
