The difficulty comes when needing to change strings quickly or needing to change or drop tune. This bridge usually stays in tune very well no matter how dramatically you use it because there is a locking nut installed to help keep the guitar in tune. With this bridge you can dive bomb and lift squealing harmonics to the heavens by pushing or pulling on the tremolo bar. The Floyd Rose is the best known by the guitar shredding community. This type of bridge requires regular checking of tuning as the strings can get out of tune much easier on this bridge type. Tremolo bridges are usually set up as 'floating' which means that if you push or pull on the tremolo bar you are able to change the pitch of the note or chord that you are playing. For most guitarists this is not much of a problem and this tends to be the preferred bridge type. The main negative for this type of bridge is that you don't have the flexibility to change the pitch of a chord easily as you do with a Tremolo. Fixed or Hardtail bridges have great tuning stability and are easily retuned or drop tuned without affecting the remaining strings. There are 3 main bridge types that you regularly find on electric guitars, Fixed or Hardtail, Tremolo, and then Floyd Rose. How do I know what guitar bridge type suits me?
