The new Short bass one model comes with a plastic bottom and a hole on the top side for a better projection. The mixed Amplification System Active / Passive is controlled by a switch. A warm and powerful sound that resembles the double bass’ one because of the Thunder Reds strings by Aquila Corde Armoniche Srl. The cutaway model guarantees a full-scale keyboard’s playability. Amplification System: Switchable through a button situated near the volume and tone knobs, you can select the piezo pick up under the bridge or alternatively the piezo transducer when necessary. The piezo is an active system with tone and volume controls: this solves resonance problems and guarantees a clean sound that’s ideal for concerts or recordings sessions. The piezo transducer guarantees high fidelity to the original sound.SCALE: 60 cm / 23.6 inch AMPLIFICATION: piezo undersaddle pickup active + piezo passive – TOP: Cedar SIDE / BACK: ABS LOGO ON HEADSTOCK: Mother of pearl FRETLES STRINGS: Red Series Aquila Corde Armoniche RED SERIES STRINGS – AQUILA CORDE ARMONICHE All Shortbass-One models are using a new type of strings specifically designed by Aquila Corde Armoniche for this instrument: the red series. Red Series strings are basically a mixture of elastic plastic mixed with copper metal powder to make the sound rich and powerful. They are designed and manufactured at our headquarters in Vicenza – Italy Key Features: 1) A powerful sound, rich and warm, excellent sustain. The combination of ShortBass-One with these new strings produced a truly innovative sound with sonority very similar to the timbre of the double bass. There is nothing comparable with these strings on the market, either wound or in alternative materials. 2) They do not rotate and do not stick: in the past the attempt of many companies by experimenting with new materials to produce alternative strings to traditional wound strings achieved poor results due to resistance of the material to the fingers, such as for silicone, or for annoying rotation of the string that makes extremely difficult to play.
