Hi,
guess what you read was:
D'Addario ECG 24 chromes - strings set flatwound polished, stainless steel
What i know is he is using
D'Addario EXL110 Electric Guitar Strings (the strings most of us using)
and sometimes
D'Addario ECG24 Chromes Electric Guitar Strings (polished)
With D'Addario EXL110 you won´t do anything wrong.
Cheers
