This unit was stored as a backup, so it has been used very little. Overall, it is in very good condition and functions well. I also own the current ME-90, but while the ME-90 has a clear and refined sound, the ME-80 has a thick, core-rich sound with excellent presence. It is especially recommended for those who want to use it mainly for rock and hard genres. [Included Items] ・Genuine adapter ※Instruction manual is missing. ※The outer box from the ME-90 will be used and the item will be carefully packed for shipping.
