Ok, so just recently got my one and only pedal - the Alpha Omega. And upon unboxing, my initial joy was soon replaced with dismay. No battery option, and no included power supply. Yeah, my own fault for not reading the fine print when I ordered it. But seriously, the whole Euro "save the environment" thing just went too far. I could be using rechargeable 9V batteries . And I hate having extra cords on stage. Really p***ed me off having to then wait till the weekend to go and buy a power supply. That aside, I love the tonal capabilities of this thing combined with my Thumb 6 NT. Maybe a suggestion for Darkglass to incorporate an internal lithium battery for those who want to eliminate the need for running power to the front of stage.
