AKAI's legendary MFC42 analog filter module. Operation has been confirmed, but please note that due to the complex internal routing, not all functions have been verified. It's quite useful, as it can be controlled and recalled via MIDI. It's been serviced and is running smoothly, so I hope you'll find it useful. While there may be some age-related deterioration, considering its vintage, it appears to be in like-new condition, having been hardly used. The appearance is undoubtedly clean, but please consider the visual assessment to be subjective. Please note that due to the possibility of unintended exchanges or shipping issues, we ask for no claims and no returns. To reiterate, operation has been confirmed, and we have saved a video of it. Therefore, if there is a malfunction after delivery, it will be handled through communication with the shipping company. We will assist as much as possible, but please handle the receipt promptly. Please feel free to ask if you have any questions.
