What are the advantages and disadvantages of string penetration and fixed bridge type?

There are various types of guitars and basses.

The way of passing the strings is also different.

A string passed through the bridge.
Passing strings from the back of the body

There are two types.

What is the back of a string?

The back of the string is a method of making a hole in the body of the instrument and passing the string from the back of the body.

If the instrument itself does not have such specifications, it will not be possible.


The fender stratocaster and the musicman’s bass are all through.

Gibson’s Les Paul and jazz bass go through the bridge.

Recently there are models that can do both.

Each has advantages and disadvantages, and people’s tastes vary.

It must not be through! Some people say that either is acceptable.

Of course, there are people who say that a bridge is good.

What are the merits of string penetration?

So what are the advantages of passing the strings from behind?

I will explain what was good to see through.

You can earn tension by looking through the strings

Tension can be gained by passing the strings through.

To earn tension means to increase tension.

When the tension is increased, the string height is less likely to become dull when the string height  is lowered, so the string height can be lowered accordingly.

The back of the string is less tensioned and easier to finger

And if the string height is low, it is easy to play (easy to finger).

This is for people who want to play with a lower string height even if the tension is a little stronger.

If tension is strong, It is easy to pick because it is tight.

If tension is strong, it is stretched, there is little feeling caught (picking) when picking.

For this reason, it is suitable for people who prefer to pick up when the tension is strong.

On the other hand, since the tension becomes tight, fingering is a little difficult.

I think that the string height should be lowered and balanced around that.

The back of the string can also be used to adjust the volume depending on the string

The back of the string can be used to adjust when the volume varies depending on the string.

I think the volume is determined by the sustain and attack of the strings.

So, models that allow both through-through and bridge-through can be adjusted by the strings.

If you want to keep the volume down, you can relax the tension.

This area is a bit annoying, so please refer to another article.

What are the disadvantages of string penetration?

So what are the disadvantages of passing the strings from behind?

If you look at the merits, it feels like you’re full of good things.

The back of the string feels like a sound

If you put the strings behind, it sounds like a clogged sound.

This may depend on the model.

The ESP AMAZE bass that I use is designed to pass strings from the back of the body and from the bridge.

I actually tried both, but the back was filled with sound.

Theoretically, when the tension goes up, the vibration of the string is suppressed, so it makes sense that the sound gets stuck or doesn’t resonate.

Also, if you raise the string height, the angle of the string will be steep at the saddle even if you pass through the bridge.

If you try it, you can see it, but if you raise the string height, you can hear the sound getting stuck.


So it can be convinced that the sound gets clogged when you see through.

Because the string has a sharp angle with the saddle, the vibration around the saddle is suppressed.

As a result, the sound will be muted and sustain will be reduced.

I think there is a preference, but I like the sound of Bing, so I couldn’t find it.

In the end, it passes through the bridge.

Advantages and disadvantages of string bridges

So what are the advantages and disadvantages of passing a string through a bridge?


This is the reverse of the previous show.

Benefits of string bridging

Passing the string through the bridge lowers the tension and makes the string easier to vibrate.

I tried it many times with my instrument, but the body of the instrument sounded more like fixing it to the bridge without seeing it through.

The sound is good.

This seems to be the same for guitars.

When you want to produce nuances, it’s important to sound!

I often use this “sound of the body” when I want subtle nuances.

For this reason, emphasis is placed on “sounding the body”.

“Even if the body of the instrument does not sound, it doesn’t matter if it passes through an amplifier.”

I don’t think so.

After all, even with electric guitars and electric basses, the potential of raw instruments comes out of the amplifier.

If not, there will be no price difference due to the difference in the material of the wood. !

If you don’t want the body to sound, you can do a bridge mute (a technique of placing a hand sword that picks into the bridge and touching the strings to cut the sound).

If you want the sound, just play without muting.

Because I can use these various ways, I value the sound.

Also, sustain (sound stretch) will also improve if you pass through the bridge.

It is quite important for me that the sound grows.

I think white notes are important for bass.

What is a whole note?

It’s a note that keeps the sound stretched.

 I want you to keep the volume as high as possible from the rise of the sound to the point where the sound disappears.

I really want sustain at times like this.

If that happens, you will place an emphasis on the “sounding body”.

That’s why I like “string bridge through”.

Disadvantages of bridging strings

This is also the opposite of the merit of the show-through.

Because the tension goes down, the strings become dull.

It is difficult to pick if you lower the string too much.

This is a difficult place because the higher the tension, the lower the string height.

However, I give priority to sound quality and make the strings pass through the bridge.


Even if you can’t choose between back and bridge, string tension can be controlled to some extent. Please refer to the following article.

How to raise / lower string tension


  • Select the back of the string when you want to pursue ease of playing
  • Choose the string bridge fixed type when you want to pursue the sound

That was my conclusion.

Of course, there are various characteristics depending on the instrument, so it cannot be said unconditionally.

However, if you keep the above points in mind when choosing an instrument, it will be helpful.

Today was the back of the guitar and bass strings.
