Just a note of observation: when I saw Springsteen on his most recent tour he's playing a tele with a Bigsby stamped not with the "F" but with the traditional "Bigsby patent" although I never noticed him using the trem arm so maybe its just for looks, or maybe it alters his tone somewhat, I have read where SOME think that the aluminum Bigsby adds a certain sweetness to the guitar's tone. Having modified one of my own guitars with an add on Bigsby (not a Tele) I don't hear it... But thats what "the Boss," a true Tele-man, is using on many of the new songs, just a note,
take care everyone,
the Rookie
