Of course, in that video Dallas talk about the specific 011-049 strings on Explorer and in general, he talks about the gauge strings used on all guitars for standard and drop down tunings.
For example, I'd like to understand what strings gauge Edge uses on his 66' telecaster for vertigo
I was supposing he uses 010-046 since that guitar is using in standard tuning ?
well guitars strung with heavier strings are ones used in songs where Edge heavily strum, like Elevation or something. Im sure Strats or Tele are somewhat similar, though Tele is used in Vertigo so maybe heavier bottom strings?
