I'm not sure Ultimate Apex is a good stand for a musician working with pedals. In previous posts there were some criticisms about the equilibrium of the stand. It seems to be indicated exclusively for situations where you stand on stage. I used to work with Quiklok X stand (a simple T-10 with attached music stand and mic boom). I'm presently using a Quiklok Monolith and I am very happy with it. It's heavy and not cheap but it folds completely flat (very convenient) and it's extremely stable. And there's plenty of space for pedals.
