I consider vintage strat tremolos an iconic piece of guitar heritage and engineering. They are undoubtedly one of the most common bridges used on electric guitars, yet many players find certain aspects about them frustrating. On the positive side, I have always found that these bridges sound great and bring a really cool vibe to the guitar. The drawbacks that are typically cited are tuning stability, play in the tremolo arm, rough saddle adjustment screws (this hurts the palm of your picking hand), strings not staying in the center of the saddle, and probably others I’m forgetting about. Interestingly enough, some of the most prolific guitarists that favor strats manage to not be deterred by these issues, particularly players like Jeff Beck & Scott Henderson come to mind. Both of these guys make heavy use of their tremolos and almost embed the tremolo bar into their picking hands.
