All the shippers I know of require the bass to be packed in a hard case, then a cardboard box.
Unfortunately the only case I have is a moulded shaped fender bass case which I would have to charge for and would be say at a guess £75 I still have to find a box and a very rough guestemate on size and weight using ups insured for £750 is another £67.02
So shipping alone would be 160 euros although you do get a fender case, in addition to the cost of the bass
Please bear in mind that I would need to get a suitable box, to confirm the weights and dims,
