Knowing How to Play The Rubber Bridge Guitar

Before we dive into creating your rubber bridge guitar, let’s first explore what makes this modification so special.

The Rubber Bridge Guitar: What Is It?

A rubber bridge guitar is an acoustic guitar with a rubber bridge saddle, replacing the traditional bone or plastic saddle. This simple yet effective modification can make a difference in your guitar’s sound and playability. Many guitarists, including the renowned Reuben Cox, swear by the unique qualities of a rubber bridge guitar.

Why Choose a Rubber Bridge Guitar?

Now that you know what a rubber bridge guitar is, let’s discuss the compelling reasons to consider this modification.

Enhanced Sound Quality: One of the primary benefits of a rubber bridge guitar is its ability to produce a warm and resonant tone. The rubber saddle dampens excessive vibrations, producing a more balanced sound with rich harmonics.

Improved Sustain: Rubber bridge saddles provide excellent sustain, allowing your notes to ring out longer and more clearly. This can be especially beneficial for solo performances or intricate fingerpicking styles.

Greater Playability: Fingerstyle players often favor rubber bridge guitars due to their comfortable feel. The rubber saddle can make playing chords and intricate melodies easier on your fingers.

Durability: Rubber is a robust material that can withstand the rigors of constant string tension. Your rubber bridge guitar will likely require less maintenance than traditional bridge materials.

Materials and Tools You’ll Need

Before we start the conversion process, gather the following materials and tools:


  • Acoustic guitar with a traditional bridge saddle.
  • Rubber bridge saddle (available online or at music stores).
  • Sandpaper (various grits).
  • Measuring tools (ruler, calipers).
  • Pencil and eraser.
  • Masking tape.
  • Guitar strings (to rest your guitar after the modification).


  • Screwdriver.
  • Needle files.
  • Sanding block.
  • Razor blade or sharp knife.
  • Clamp (optional but helpful).
  • Tuner.

Preparing Your Guitar

Now that you have everything you need, it’s time to prepare your guitar for the rubber bridge conversion.

Remove the Strings: Start by loosening and removing all the strings from your guitar. This will make it easier to work on the bridge area.

Remove the Bridge Pins: Using a screwdriver, gently remove the bridge pins holding the strings. Be careful not to damage them; you’ll need to reuse them later.

Take Photos: Before you proceed, take clear photos of the bridge area from various angles. This will be a reference if you need to reassemble the bridge components.

Shaping the Rubber Bridge Saddle

Now comes the crucial step of shaping the rubber bridge saddle to fit your guitars. Follow these steps carefully:

Measure the Original Saddle: Use a ruler or calipers to measure your original saddle’s length, width, and height. Note these measurements; they’ll help you shape the rubber saddle to the correct size.

Trace the Original Saddle: Place the original saddle on top of the rubber saddle and trace its shape onto it using a pencil. Ensure that the two saddles align perfectly.

Cut the Rubber Saddle: Carefully cut along the traced lines on the rubber saddle using a razor blade or sharp knife. Take your time to achieve a clean and precise cut.

Fine-tune the Fit: With the rubber saddle cut to size, use sandpaper to refine the shape and ensure a snug fit in the bridge slot. Sand the sides and bottom of the saddle as needed, checking the fit frequently.

Test Fit the Saddle: Once you’re satisfied with the fit, insert the rubber saddle into the bridge slot of your guitar. It should sit flush and stable.

Measure the Action: Measure the string action height above the 12th fret. Adjust the rubber saddle’s height if necessary to achieve your desired action.

Reassembling Your Guitar

With the rubber saddle-shaped and fitted, it’s time to reassemble your guitar.

Insert the Bridge Pins: Carefully insert the bridge pins back into their respective holes, securing the rubber saddle. Use a gentle twisting motion to avoid damaging the rubber.

Restring Your Guitar: Reinstall the strings, making sure to follow the correct order and tuning. Use a tuner to ensure your guitar is in tune.

Test and Adjust: Play your newly modified rubber bridge guitar and listen to the changes in tone and sustain. If needed, make further adjustments to the saddle height to achieve your desired sound.

Maintenance and Care

To keep your rubber bridge guitar in top condition, follow these maintenance tips:

Regular Cleaning: Wipe down your guitar after each session to remove dust and sweat. Use a damp cloth to clean the rubber saddle gently.

String Changes: Change your guitar strings regularly to maintain the best sound quality. Old, worn-out strings can affect the tone and playability.

Check the Action: Periodically check and adjust the saddle height to maintain your preferred string action.

Humidity Control: Store your guitar in a controlled environment with stable humidity levels to prevent damage to the rubber saddle and other components.


What Is A Rubber Bridge on Guitar?

The name contains the easiest solution. It’s a rubber-bridged guitar. You must first remove the stock bridge to install a rubber bridge on your instrument. However, let’s address that later. First, we must investigate how a rubber bridge works. You may already be aware that the tone is affected by the bridge.

Do Rubber Bridges Create A Muted Sound?

Naturally, rubber bridges produce a muted sound. Nonetheless, if the right gear is used, projecting sound into audiences during performances may be simpler. Fitting an electric or acoustic guitar with a high-output pickup and rubber bridge is one of the finest solutions to this problem.

How Do You Make A Guitar Bridge?

Glue two cardboard strips above and below the sound hole to make the bridge. The strips should be right between the string holes and the top-to-bottom edge of the sound hole. The strips will help lift the strings off the guitar’s body and give you a better sound. Poke four to six holes through the remaining two cardboard strips.


Congratulations! You’ve successfully transformed your acoustic guitar into a rubber bridge beauty, unlocking a world of enhanced sound quality and playability. Reuben Cox and many other guitarists have experienced the magic of a rubber bridge guitar, and now you can, too.

This modification requires patience and precision, so take your time during each step. With proper care and maintenance, your rubber bridge guitar will be your faithful companion on your musical journey, providing you with a unique and beautiful sound for years. Enjoy your newfound sonic versatility and let your creativity flourish!
