【Product Description】 The Acoustic Image Contra Series III (1ch), a masterpiece of acoustic instrument amplifiers. This model is becoming increasingly rare due to the manufacturer's closure. 【Operation and Condition】 ・Perfect working condition. There is no crackling or noise, and it outputs a very clear and powerful sound. ・The exterior is in "player's condition." It has been used in live performances, so there are some signs of use and minor scratches, but there is no major damage that would hinder performance. I think it's in good condition because I took good care of it. Pop noise occurs when the power is turned on/off, but this is a characteristic of this series and does not affect the sound quality or stability during use. If you are concerned, it is recommended to set the volume to minimum before operating to protect the speakers. 【Features of this Model】 ・Overwhelming lightness (approx. 9kg): Despite its 300W output, it can be easily carried with one hand, making it useful for live performances with a double bass. ・Supreme natural sound: The Contra is unique in its ability to reproduce the original sound of the instrument without compromising it, and to reproduce bass with a sense of air. It's like making the entire 360-degree box resonate. 【Included Accessories】 ・Dedicated carry bag (This bag alone provides peace of mind during transportation) Can be carried over the shoulder. ・Power cable The Series III is rarely seen on the used market. I hope to sell it to a player who will take good care of it.
