Thanks for your reply. As to the power supply, having toured around the world for a good part of my career, it is never fun when a power supply goes down. If the brick powering your board goes down, you may only have a few minutes to find a solution. Not everyone carries a spare, and not every country has music stores that are open late. Being able to power a pedal from a wider range of supplies can be make-or-break, and personal experience can testify to how useful this can be in a pinch. Additionally, in a lot of creative situations like recording studios, there isn't a built and dressed pedal board, but a large selection of pedals to build up a quick chain for a song. In those cases, having worked at studios for awhile as well, losing time looking for an extra suitable supply can mean losing the creative moment.
