How to Adjust Tremolo Claw Springs for Balance

Why spring balance matters

A tremolo claw has two or more springs that pull the bridge backward against the strings. If the spring tension does not match the string tension, the bridge tips forward or backward, causing tuning instability and inconsistent vibrato response. A balanced setup lets the bridge float slightly above the body, so pushing the arm lowers pitch and pulling it raises pitch evenly. For more on spring configurations, see guitar tremolo springs.

Strings are the first point of contact between your hands and the guitar's voice, and the maker's guide notes that string choice affects feel, tuning stability, and response. The springs are the other half of that equation: they have to counter the total pull of the strings. When the two forces equal out, the bridge stays level and returns to the same spot every time.

If you are new to tremolo systems, the principle is simpler than it sounds. You are just equalizing two opposing forces. The screws on the claw are the adjusting mechanism, and small turns make big differences in float angle.

Tools you need and initial checks

You need a Phillips or flathead screwdriver that fits the claw screws (most Fender-style parts use a Phillips head), a tuner, and possibly a ruler or a set of feeler gauges for measuring bridge height from the body. You do not need any special tools beyond that. If you are unsure about the overall setup, a guitar action and setup guide is a good starting point.

Start by checking the current bridge position. With the guitar in standard tuning, look at the bridge base plate from the side. A floating bridge should tilt up at the front by a small amount, usually around 1/8 inch (3 mm) off the body. If the bridge sits flat against the body, the springs are pulling too hard. If it tilts up more than 1/4 inch (6 mm), the springs are too loose.

Before adjusting, make sure the strings are reasonably new and properly stretched. Old strings change tension as they wear, which makes the setup inaccurate. Also check that the tremolo arm screws in cleanly and does not bind.

Work in a well-lit area and keep the guitar on a stable work surface. You may want to place a cloth under the tremolo cavity to catch any dropped springs.

Setting the float with claw screws

The claw is the metal plate inside the spring cavity on the back of the guitar. It is held by two screws that thread into the body. Turning the screws clockwise pulls the claw toward the neck, increasing spring tension. Turning them counterclockwise does the opposite. Understanding how the tremolo block works can help; see bridge types explained.

To lower the bridge float (make it sit flatter), tighten both claw screws by the same amount. To raise the float, loosen both screws equally. Always make adjustments in small increments, then retune and recheck.

A practical method: after each small turn, retune the guitar. If the bridge returns to the same position after you use the tremolo arm, the balance is good. If the bridge sags forward, spring tension is too high. If it rides back, tension is too low.

Many players prefer to set the float angle to about a 1/16 to 1/8 inch lift at the front edge. But the right angle depends on how you use the arm. For gentle vibrato, a smaller float works. For dive bombs, you'll need more clearance.

• Tighten claw screws clockwise to increase spring tension and lower the bridge.
• Loosen claw screws counterclockwise to decrease tension and raise the bridge.
• Always adjust both screws equally to keep the claw parallel to the body.
• Retune after every small adjustment and test the bar.

Checking tuning stability after adjustment

Tuning stability is the real test. After setting the float, tune to pitch and then use the tremolo arm for a few bends. Release the arm and check the tuning. The strings should return to pitch cleanly. If they go sharp or flat, the spring tension is off, or the nut and bridge are binding. For persistent issues, see our guides on guitar tuning instability and improving tuning stability.

Listen for any metallic noise from the springs. A rattle usually means a spring is loose or rubbing against the cavity wall. You can bend the spring hooks slightly to reposition them.

The manufacturer's advice on string care applies here: stretched, fresh strings hold pitch better. Old strings compromise the whole setup.

Fine-tuning for feel and response

Once the bridge returns to pitch, you can fine-tune the feel. A stiffer spring tension makes the bar feel heavier and return more abruptly. Lighter tension gives a softer, more fluid feel but can reduce tuning stability if too loose.

If you have multiple springs, you can change the count or arrangement. Most Strat-style guitars use three springs, but two springs give a softer feel, and four or five make it stiffer. Changing the number of springs is a separate step from screw adjustment, but it shifts the whole balance.

For players who do a lot of subtle vibrato, a slightly forward float (more slack) can be preferable. For aggressive use, a more solid return might be better. The right setting is subjective, so experiment within the range where tuning stays true.

Also check that the tremolo arm angle suits your hand. If it sits too low, tighten the arm tension screw inside the bridge pivot. If it's too high, loosen it.

Common issues and how to avoid them

The most common mistake is over-tightening the claw screws. This slams the bridge into the body and can cause the strings to break at the bridge. Work slowly and measure the float after each turn.

Another issue is an uneven claw. If the two screws are turned to different degrees, the claw tilts and puts uneven pull on the springs. Keep them equal.

Spring fatigue is another factor. Over years of use, springs can stretch and lose tension. If you can't achieve a good float with the screws all the way out, new springs may be needed.

Finally, remember that float height interacts with intonation. If you move the bridge position, recheck intonation at the 12th fret.

What to pick for your use

Questions

How do I know if my tremolo claw springs are too tight?

The bridge sits flat against the body instead of floating, and tuning goes sharp after you use the bar. Loosen the claw screws a little and retest.

Should I adjust both claw screws the same amount?

Yes. Keeping the claw parallel to the body ensures even spring tension on both sides. Uneven adjustment can cause the bridge to tilt sideways.

How often should I adjust the claw springs?

Only when you change string gauge, change tuning pitch, or notice tuning instability directly tied to the tremolo. It is not a routine maintenance item. For more on string-related tuning issues, see electric guitar string materials.

Can I adjust the claw springs without removing the back plate?

No. The claw is inside the spring cavity behind the back plate. You need to remove the plate to reach the screws.

What if my springs are stretched or corroded?

If the screws are at their limit and the float is still off, new springs are the fix. Springs are consumable parts and can be replaced in minutes.
