The guitar Bruce Springsteen bought in 1973 had a neck from a 1957 Esquire, and a body routed for four pickups and four outputs (part of a scam certain session players employed to earn four times union rate for playing four ‘tracks’). The resulting guitar was feather light and rang like an acoustic from all the wood removed. Bruce used it in continuously from 1973-2012, and still records with it.
