As a solution to batteries, I bought this power supply:


However I now have 8 pedals (the supply only has 6 outlets) and I was just wondering whether simply buying another daisy chain would be suitable? Or would this overload or something?

Bearing in mind that one of my pedals is 18 volts but I have a short cable that changes a 9V supply to 18V

would doing this be completely fine? Or would I need to buy something a bit more like this:


Thanks in advance
