Hey guys,

I just bought a Boss me-70 multieffect pedal and a 9V dc power supply, 1700mA. But when i use this power supply is creates unwanted noise.

I have 2 questions, the me-70 itselfs says DC in. but the manual asks for an ac adapter? And they are asking specific for a boss PSA adapter. is this really needed as i read that any 9v DC adapter could do?

But where is the noise comming from?
