Center block made of aluminum
At first glance, aluminum in instrument construction is nothing new. It has been used mainly as a neck material by a few instrument makers in the past.
The vibration behavior, the rigidity, the neutral and fast sound transmission are just a few of the many advantages of this material. The relatively low density for a metal also makes this material attractive not only in instrument construction.
Of course, the non-ferrous metal aluminum, despite its low density of 2.7 kg / dm3, is significantly heavier than normal tonewood, and often feels quite cool when playing the guitar. That is why EBG-Instruments deliberately refrains from using aluminum in the construction of its instrument necks and the body wings. We only use it where the material increases the sustain and attack of the instrument, and does not change the feel or feel.
We did not increase the overall weight of our instruments with the aluminum center block, as we milled out the body, and thanks to the webs and walls, we can keep it very stable, free of distortion and light. Thanks to the wooden body wings, all of our instruments feel classic, familiar and warm when they are played.
The aluminum alloy that EBG-Instruments uses is cold rolled and not cast. In contrast to cast aluminum, we have a significantly more homogeneous density without air inclusions that would attenuate the sound signal and thus change it. The change in tone and the loss of sustain due to air inclusions are known, for example, from guitar bridges or bass bridges made of die-cast zinc.
Through countless trials and tests, we have found a great aluminum alloy with many advantages. The aluminum center block forms the heart of the neck, saddle, strings, bridge and body. This ensures a quick and neutral sound cycle when generating the tone.
Many customers ask me whether the wood or the type of wood on the body still plays a role.
Of course, the wood or the type of wood still plays a role in our instruments. The aluminum on the center block behaves neutrally. It just swings very quickly. You can of course control the character of the instrument by choosing different body woods, neck woods and fingerboards. We would be happy to advise you on the selection and your desired configuration.
Carbon as an alternative to wood - does it even work?
Wood has been successfully and sustainably produced and used in instrument making for centuries. The advantages of wood are obvious and do not have to be proven again.
However, there are now just as suitable modern materials that are not fundamentally better, but have their advantages in detail, and are therefore very interesting for instrument making.
Carbon, for example, is such a material. It sounds similar to wood, and its very special properties make it extremely interesting for instrument making.
It has a very high rigidity and can withstand very high mechanical loads. Due to its networked, braided and multi-layer construction, it not only has a weight advantage with a very thin construction, but also forms an incredibly stiff and distortion-free component.
Especially with bass necks, the noticeably higher rigidity in contrast to wood is quite noticeable.
In addition, carbon has an extremely low coefficient of thermal expansion and is less sensitive to weathering than wood.
EBG-Instruments has managed to use special fillers to make the carbon bass necks not heavier than a wooden neck, but much more rigid and modern.
For fine adjustment of the neck curvature, EBG-Instruments always uses a "double action" truss rod in the carbon neck, despite the high rigidity.
Thus, despite the high rigidity, it is always guaranteed that the desired neck curvature (even with different fingerboard materials) can be set and readjusted exactly according to customer requirements.
In addition, every EBG-Instruments carbon neck is made of real CFRP and is hand-laminated in multiple layers and created as a carbon fiber neck.
This product is also 100% handmade and completely made in Germany.
"Fatsus" - the bass bridge from EBG Instruments.
EBG Instruments has been installing its own bass bridge since 2020. The specially designed 3D bass bridge combines full functionality made of solid and CNC milled bell brass with unique simplicity.
Due to the massive bell brass and the precise CNC production, the sound is transmitted directly and clearly to the body without the losses that are common with zinc die-cast bridges. This leads to a clear sound dynamic and a significantly better sustain of the instrument.
Due to the different depths of the recesses on the stainless steel saddles, the bridge is adapted to a 12 “fingerboard radius as standard. The fingerboard radius is compensated for by the different depths of the recesses on the string rest of the bridge.
Thanks to the height adjustment and the rotating stainless steel saddles, the bass bridge can of course also be used with other fingerboard radii.
The bridges are available for 4-string and 5-string basses and in black or nickel, each in silk gloss.
If ordered individually, the bridges are delivered in an elegant magnetic folding box including screws and keys.
The bass bridge is 100% made in Germany - Inquiries from dealers or instrument makers are welcome.
