Gabriel,
I quote from Bruce's guitar tech:
"Bruce Springsteen's Guitar
During the band's lengthy performances, Springsteen would keep a large bucket next to the drum riser filled with ice water and towels. Periodically, he would take a towel and wrap it around his head, dousing his guitar in the process. He also drank Gatorade throughout the show that would often spill onto his guitar. The moisture that built up would wreak havoc on his instrument.
"I took his guitar apart and found that it was full of this smelly, rotten, moldy crud," he recalls. "So I decided to drill holes through each pick-up cavity running through the back of the guitar. This allowed the moisture to escape without creating further damage.
"At the end of each show, however, when Bruce would raise his guitar, his shirt would have water marks adjacent to where the holes were on his guitar."
If you notice in that video you posted he has what, an ESP or Dean backing him up and carrying the load? Whatever it was it did have a beautiful unique body shape........

Based on the first video I posted that started this thread, I would say that a tele filled with smelly rotten moldy crud is not an uncommon occurrence? Plus, I'm sure those extra holes to the pickup cavities had to do something to improve the tone, you cant get much worse.
