Well I had put a wound low G string on my dolphin but yesterday noticed that the tuning machine had torn one of the screws out of the back of the headstock because the stress was too high from the Low G. I also don't like the sound of a low G on a soprano ... just saying don't bother doing it unless you feel super experimental .... This dolphin with two holes on it and a tuning maching issue is ready to be spare parts for my NEXT dolphin!
