Re: 12 pedal pedalboard power??
I'm using an MXR M-238 ISO-Brick for the higher draw pedals and a Truetone 1-Spot chained for the lesser amp 9V pedals. Pedal board changes so much I'm not going to keep rebuying power supplies based on the number of pedals to just have one box. I just add what is needed, and can split the board later when needed.
