The EVO line maintains the same traditional building principles.
For its body structure, we chose a aluminum alloy that behaves similarly to classical tonewoods. Its sound board is in Italian red spruce. Its neck is in Balkan maple. Two sound posts act as natural sound equalizer.
The EVO instruments maintain the sound quality and rich tones of the Hollow Body acoustic line. As in BASSO, they are ergonomically designed to preserve a player’s correct posture. Our luthiers make sure that each EVO is fine-tuned to be easy to play with a smooth neck, a fingerboard properly dressed, a bridge correctly curved and set up.
The EVO instruments are built with rigorous standards and a variety of accessories are also offered.

EVO Techno is the core of the original design. It is 100% EVO but without the fiber carbon jacket, tailpiece and inboard electronic. During development, we came to value its bare simplicity and decided to offer it as a second EVO model. EVO Techno is easy to customize (see for instance the ‘da gamba’ extensions) and it is priced lower than the EVO Carbon. As any other EVO instrument, the neck is in select balkan maple and the sound board in 1st quality red spruce from Val di Fiemme.

Neck system

The Alter Ego neck system allows to adjust string action by changing the neck angle. No bridge adjusters are needed anymore.
The system is quick and precise and can also be done during a performance.


Adjustable string action


EVO is offered withan active electronics system, powered with a 9V alkaline battery, and two sound sensors: one polymeric pickup, placed under the bridge, and a bridge-mounted microphone.

The proprietary active system is conceived to enhance the acoustic qualities of the ALTER EGO instruments. The two sound sources each have their own volume control so that a musician can easily shape their own desired sound.
In addition to the volume, a switch control for the microphone provides a quick adjustable “arco” setting.
