I've always used pedals, but I used to be the guy running off of 9V batteries. However, I started getting drawn into other projects and session work. One session gig I was a part of, I came through very dry, no pedals, just guitar and amp. But as the music evolved, I heard how my pedals could have made a better dynamic so I purchased the board and power supply. Pretty great buy. The only thing that sucks, for me, is the weight since I use mass transit. It's great for a pedal rig and I give it a 5/5.
