Amatista electric upright basses have an excellent audio response, achieving an acoustic instrument sound alike, at both pizzicato and bow playing modes, while avoiding the problems of live sound performances, especially in formations with electric instruments, drums or winds.

They were designed to be used in all the situations where our acoustic bass becomes less practical, because we know how damaging the excessive movements are and also, environmental changes in temperature and humidity.

FAQ ( Frequently Asked Questions )

  • You ship internationally

    Yes, with private couriers (FedEx or UPS). Shipping cost are available on the websites of these companies

  • What are the instrument’s measures and weight

    The standard model measures 152cm long (folded), 18cm wide and 15cm high. It weighs approximately 4.8kg

  • What kind of maintenance is required?

    Maintenance is very low: check the battery level and verify that the jumper pins are making good contact with the captors.

  • The strings affect the sound? What strings do you recommend? 

    Yes, they do. It depends on the style, I personally recommend Pirastro Flexocord.

  • Can gut strings be used? 

    Yes, the microphone system is not magnetic, so it does not require that the strings are metal only.

  • I have less volume, a slight distortion and low batery LED lights. What is the problem? 

    The battery is running out. It’s time to change it!

  • You need to use a special amplifier

    In an electric instrument, the other half of the sound is in the amplifier being used. The Amatista Basses were designed to sound good in common equipment, and even small, but we recommend using speakers that can reproduce low frequencies emitted by the instrument.

  • The sound of an EUB (Electric Upright Bass) is equal to that of an acoustic bass? 

    No, we must not forget that an electric instrument sounds using external equipment, providing a wide range of possibilities of sound, similar to that of an acoustic instrument, but not the same!

  • The sound has changed. And using arc, the volume does not increase. Why is this happening?? 

    Because the bridge is not properly supported on the captors. To solve it, with the instrument connected to the computer, arrange the bridge to find the point of highest volume and clarity.

  • What differences are there with a Baby Bass

    The Ampeg Baby Bass does not have the scale or the curvature of the bridge of a traditional bass. It’s microphones are magnetic. It does not provide good performance with bow.
