I have a Technics SZ-FC2 Foot Controller (4 pedals) for sale to the best offer. It has never been used. This is a hard to find item.
I also have an original Technics soft case for the KN1000. It is in new condition because it was never used. Also, this is a best offer. I believe this case will fit other models after the KN1000. I know it will not fit the KN6000, KN6500 or KN7000. The size is 42 inches long, 15 inches high and 4 inches deep. There is some play space wise because it is a soft case. Make sure it will fit your keyboard. There is also a compartment to carry accessories.
I can send images for anyone wanting them.
