The FX-747 features a newly designed MACH control with an expanded range to achieve slower flanger effects than any existing flanger. It produces not only jet sounds but also further "outer space" sounds. Operation confirmed: Power on OK / Sound output OK (Last confirmed: 12/28) Main unit only. Everything shown in the images is included. It is a beautiful item that has been used very little, but as it is a vintage item made in the USA, please understand that there may be imperfections such as paint lifting. This is an extremely rare item that rarely appears on the market, so this may be your last chance to encounter it in your lifetime. Highly recommended for enthusiasts of rare and unique machines!
