This is the "EXTREME GUITAR FORCE SD-9 SUPER 2020," a modified version of the Maxon SD-9, supervised by Susumu Tamura (developer of the TS808 and SD-9), formerly of Maxon. The stickers that were on the foot switch have been removed, but I think it's in beautiful condition. The stickers on the back cover and sides are still attached, so you can confirm the serial number matches the box. Operation has been confirmed and there are no problems. Please check the photos for the condition of the main unit and included items before making your decision. *Notes: Please note that this item is also listed on other flea market sites, so it may be sold out. #MAXON #SD9_SonicDistortion_ #landau
