I bought this bag from Thomann a few days ago for my Numa X 73, but there was no way I could fit the piano, not even with a shoehorn. I know from other people it should be a tight fit, but this was nowhere close. Thomann says the bag interior dimensions are (W x D x H): 1054 x 318 x 127 mm, which should fit the Numa X 73 (its 1052 x 310 x 123)
However, when I checked the Gator site it says the dimensions for this bag are:
Length 95.89 cm
Width 33.02 cm
Height 12.7 cm
which is why it obviously does not fit. So I'm guessing Gator have made a new version of this bag which is 10 cm less wide. Mine was made in march 2025.
