"Double locking tremolo"@en . . "A double locking tremolo is actually part of a double locking system that consists of a lock at the nut of the guitar, which prevents the tuning heads from being used and holds the strings taut and a \"floating bridge\", where the other ends of the strings are also vise-locked, hence, \"double-locking\". The locking system helps to keep the strings in tune while the strings are slackened to a degree which was not achieved with older tremolo systems, such as those found on Fender Stratocaster, allowing dive bombs, a rapid lowering of the pitch of a note. Since the tuning heads are ineffectual with the lock in place, the Floyd Rose bridge has heads for fine tuning; the guitar is tuned before the lock is put on, then fine tuned afterwards. Each guitar incorporated with a Floyd Rose tremolo system has springs put in the back of the hardware which create balanced forces with the strings, thus keeping the tremolo in a \"floating\" state.
