General information

From a solid block to a bridge

Every guitarist wants to bring the best from his instrument out.
Our goal is to make his dream come true...

Many musicians tell us that our guitar-bridges present an open sound spectrum that was previously hidden in the wood. An ABM product can improve the sound quality of an electric guitar how it can a sophisticated guitar pickup electronically.

But how does this work?

It is the task of a guitar bridge to transmit the musical message of the guitarist on the instrument. This component is the "interface" between the strings and body. It´s material selection and processing form and influence the transfer of the tone considerably.

To ensure the best possible sound performance, ABM products are milled from a block or plate of solid metal which has a homogeneous structure and high density. Precise CNC-production, followed by a perfect polish by hand and a flawless metallic surface, guarantee a true gem.

As basic material, various metals are used:

- Aluminium has got a very fast attack and a neutral transmission of sound.
So it can the best of the wood composition produce when the base of
the guitar is consistent.

- Bell Brass adds „rocking mids“ and tightens the bass. It offers a strong
base tone with plenty of overtones in overdrive and distortion modes
with an excellent string separation and lot of sustain.

- Steel provides a sophisticated electric guitar tone with strong sustain and
upper heights called Twang.

Briefly, Bell Brass and Steel shape the guitar sound with their character, while Aluminum acts largely neutral in the transfer of tone.

To help you in addition to the fundamental difference between milled ABM products and conventional die-casting products, we want to bring you closer to the inner core of both tailpieces in comparison.

With the naked eye you can see the uniform structure of the ABM Stoptail, while the porous die-cast tailpiece air inclusions and other impurities contains within itself that interfere with the transfer of the tone considerably.

Experienced guitar technicians know very well why guitars sometimes sound „liefeless“ and know "sagging" ABR-1 bridge types well enough, since the life of a die-cast product is limited depending on their design.

The features listed above should give you a little insight into the ABM overall concept, which represents the best combination of sound and perfect functionality. And this essence you will find in each ABM product.

As always with passion and precision
