Hey fellas, please excuse my ignorance, but I was hoping to get some help with this. I am looking to buy some pedals, sansamp, etc off of eBay, all of which use 9V adaptors or batteries. I live in Australia, where we use a different power supply. Will that make any difference if I use an Australian 9V adaptor, or a 9V battery? Surely as long as the power comes out as 9V, right? Thanks guys!
