I know the AA3 draws quite a bit of power, more than my VL ISO-5 can put out. But I have a box full of power supplies. Being able to use one would be handy at times like now when I don't need or want my pedalboard. I have a couple of old POD PSs that put like 2000 ma. The plug seem the same (not expert in these matters). Can I use one of these? I assume the AA3 will only draw what it needs and won't combust. Thanks!
