well, i pulled the trigger on some new strings for my peavey millenium. I had been looking for something inbetween rounds and the flats i already have, and i was leaning towards the ghs pressures but ended up getting a set of the D'Addario half rounds in Heavy gague, because that is what they had. and i love em! I have heard that strings make a difference in tone but wow! SOOO much better than the stock strings!! so far i love em! anyone else use these?
