This, theoretically, put a friction-free expanse of string between the bridge saddles and the secure tuning posts. I had problems with the tuning stability and I’m aware of other guitarists who did too.To dispense with the final tuning headache of running the higher strings under a string tree, the Wilkinson nut also featured secondary wheels behind the primary wheels, pulling the top three strings immediately downwards once they’d run over the main wheels. Professional reviewers assessing the model shortly after its introduction, however, reported problem-free use.That wasn’t the case with the aforementioned Japanese ‘locking trem’ Strats, which had string-clamping nuts that locked the tuning solid.
The Strat Plus shared most of those features, including the popular TBX Tone Control. 1) The Strat Plus was fitted with a set of Lace Sensors, as opposed to the regular plastic-bobbin alnico V pickups carried by the American Standard.
TUNING ENHANCEMENTS To be clear about the meaning of the word ‘locking’, and to differentiate this instrument from Fender’s Japanese System I, II and III Strats of the same era, the Strat Plus did not lock the tuning of the strings in any way.
At any time, the guitarist was free to retune in the conventional way, by turning the machine heads.
Anyone looking to emulate Stevie Ray Vaughan with a set of pitch-dropped .013s, would have been cheesed right off.
Here's how Fender advertised the Strat Plus and its American Series cohorts in 1989.
