Guitar Tremolo Springs: How Many and What Tension

What tremolo springs do

In a tremolo-equipped electric guitar, the springs are mounted in the back cavity and connect the bridge's tailpiece to a claw that is anchored to the body. They pull against the tension of the strings, allowing the bridge to float or pivot when you move the arm. Without springs, the bridge would be pulled forward by the strings and would not return to a neutral position.

The springs also affect how the bridge responds to your picking and bending. A well-balanced spring setup lets the bridge return to the same spot every time, which is essential for keeping the guitar in tune. This is why the springs are not just hardware; they are part of the tuning stability system.

How many springs you typically use

The number of springs varies by guitar model and bridge design. Many vibrato systems come from the factory with a certain number of springs, which is often chosen to match a specific string gauge and the bridge's geometry. But players routinely change that number to suit their needs.

A common guideline is to start with the number the manufacturer installed and then experiment. If you find that the bridge feels too stiff or does not return to neutral cleanly, adding or removing a spring can change the leverage. You can also change the tension of the existing springs by turning the screws on the claw. Adjusting the claw moves the entire set of springs closer to or farther from the bridge, which changes the pull.

There is no fixed rule for how many springs to use. A light touch with a floating bridge often works with fewer springs, while a heavy dive-bomb technique may need more springs to hold the bridge level and keep it stable. The key is to balance the pull of the strings with the pull of the springs so the bridge rests where you want it.

How tension affects tuning

When the spring tension is too high, it pulls the bridge backward (toward the tailpiece) more than the strings pull it forward. The bridge then rests at an angle that lowers the pitch of the strings. When the tension is too low, the strings win and the bridge tilts forward, raising the pitch or causing the bridge to rise off its pivot. In both cases, the guitar may not tune properly, and notes can drift as you play.

The tension also influences how the bridge returns after a note. A properly set spring tension creates a stable neutral point, so after you release the tremolo arm, the strings return to their original pitch. If the springs are too loose, the bridge may not return exactly, and the tuning will be off. If they are too tight, the arm may feel stiff and the bridge may not move smoothly.

This is why the setup of the spring claw is an important part of any tremolo maintenance routine. You can learn more about adjusting the claw in our how to adjust tremolo claw springs guide.

Matching springs to your playing style

Your choice of spring count and tension should reflect how you use the tremolo. For subtle vibrato and occasional dips, a light spring setup gives you a gentle, smooth feel and keeps the bridge responsive. For aggressive tremolo dives and flutters, you typically want a firmer setup with more springs or higher tension to keep the bridge from moving too far and to ensure it returns reliably.

String gauge also plays a role. Heavier strings have more pull, so you need more spring tension to balance them. Lighter strings need less tension. This is why changing string gauge often requires a second look at your spring setup. A good practice is to set the number of springs so the bridge sits level (or at your desired height) and the tuning holds during normal playing.

If you are buying a new guitar, consider how you intend to use the tremolo. You can compare different electric guitars and beginner electric guitars to see which systems are easier to adjust. Some models have locking tremolos, which are covered in our comparison of Floyd Rose versus Bigsby.

Adjusting your springs step by step

Adjusting the springs is a straightforward process. Start by removing the backplate. Look at how many springs are installed and how the claw is positioned. Loosen the claw screws to reduce tension or tighten them to increase tension, making small changes at a time.

When you change the number of springs, you effectively change the overall tension. Adding a spring increases the pull on the bridge; removing one decreases it. To keep the bridge balanced, you may also need to adjust the claw screws to fine-tune the neutral point.

Always restring or tune the guitar after making spring changes, and then test the tuning stability. If the bridge does not return to where it started, adjust again. For a thorough process, you can follow our guitar setup guide and the specific tremolo maintenance guide if you own a locking system.

What to pick for your use

Questions

Why does my tremolo go out of tune when I use it?

Often the spring tension is not matched to the string pull, so the bridge does not return to its neutral position. Adjust the claw screws or change the number of springs until the bridge comes back consistently.

Can I use fewer tremolo springs?

Yes. Fewer springs make the tremolo feel lighter and easier to move. You may need to reduce the tension by loosening the claw screws. Too few springs can cause the bridge to tilt forward, making tuning unstable.

Does the number of springs affect the sound?

Indirectly. Springs affect tuning stability and feel, which can influence your playing dynamics. They do not change the tonal character of the pickups or wood much.

What should I do after changing string gauge?

Recheck the spring balance. Heavier strings pull harder, so you may need to add a spring or tighten the claw; lighter strings may allow you to remove a spring or loosen it.

Are tremolo springs all the same tension?

No, spring sets can differ in tension rating. However, the tension is also controlled by the claw screw position, so you can often adjust one spring set to cover a range.
