This power supply is a winner

I power my entire pedal board with this one supply. With 500 mA I can power 7-8 pedals in a daisy chain with no problem. Very good quality and works perfect with no noise. I have own this power supply for over two years with no problems whatsoever. This one is a winner and you cannot beat the price.

Works great

Got this to power my DD-20 delay because it burned through batteries like nobody's business, I've been using it with a TU-3+parallel cord so it powers both pedals. It has a really long cord, so even if the outlet isn't close you have a good chance of reaching it. Overall, another good Roland product.
