As for which brand for which of Edge's guitars, I am not certain.
The Martin 12-string one is probably for the Martin 12-string that Edge was playing "Drowning Man" on during the Barcelona rehearsals.
Also guessing that one of the heavier sets would be used for the tobacco sunburst Stratocaster being used for "Sunday Bloody Sunday", as it is tuned to down to "D".
The Edge's guitar strings:
D'Addario EXL110 XL Reg Lite .10-.46
D'Addario EXL115 XL Blues Jazz .11-.49
D'Addario EXL116 XL Medium Top Heavy .11-.52
D'Addario EXL 140 Light Top/Heavy Bottom .10-.52
D'Addario EXL 150 Light Elec 12 String .10-.46
D'Addario Phosphor Bronze Wound EJ15 Extra Light .10-.47
D'Addario Phosphor Bronze Wound EJ26 Custom Light .11-.52
Martin MSP 400 Bronze .10-.47
Martin MSP 4050 Bronze Custom Light .11-.52
Martin M500 Extra Light Acoustic Bronze 12 String .10-.47
Ernie Ball P02233 12 String Electric .009-.046
Edge_Orchestra, do you happen to know what brand/model/type of strings goes with each of the guitars? The 12-strings are fairly easy to figure out, I suppose, but what about the rest?
