Hey so my new ME70 says it needs a PSA adapter, whereas mine in PSU. will it work? willi it break it? i would just go and buy a new one but Boss say a lot of things that arn't true to get you to buy a £20 Boss adapter
if the voltage output and draw are the same, it will work. it should say either on the pedal, or in the manual what the draw is (look for a number with Ma after it.) and look on the adapter
I'd just get a One Spot. Way better than any crappy Boss adapter. And it has 1700mA, which can power up to 8 pedals. Pretty much renders the Boss adapters useless.
