Yamaha Original Adapters?
 

Hi,

Anyone here uses a non-original yamaha adapter, for their yamaha instrument?
I just bought a DD65 electro-drum. It's working with batteries now. But I don't want to buy battery every week.

Original yamaha dd65 adapters are $40.
Normal adapters(same as 9v and Amper) are maximum $5.

If I don't use original Yamaha adapter, would it be a problem? I used non-original adapter for a little time. There wasn't a problem but I am asking it in the long run.

Thanks.
