Resonance has been the main focus at Alter Ego since 1991We strived for creating an ideal vibration, rich in harmonics, that could be fully picked up by our electronics. Our string instruments are the result of this research. They are manufactured in Italy and are designed for those players who seek superior acoustic qualities in amplified instruments.


Our RES instruments fulfill the most important demands that professional musicians have: playability (well-dressed keyboard, bridge setup, adjustable action, ergonomics), portability (removable neck, expandable travel gig bag), and quality of materials (select Balkan maple, red spruce from Val di Fiemme).

While there are several instruments that claim the same, the ALTER EGO instruments stand out for their rich pizzicato and arco sound. The sound of the RES instruments is not created electronically, but, exactly as in a traditional instrument, it stems from the balancing tensions between an instrument’s vibrating parts, among which the sound board constitutes its pulsating heart.

The concept is simple: the better the sound source is, the simpler and more linear the electronic component will need to be. In our RES instruments, the sound is amplified, never rectified.

Lastly, our engineered production has allowed us to decrease costs and offer low prices and worldwide customer care.
