12/3 SO or better? (For stage use.)
The cables in question are not SO but I'm using them to power Seachangers which can't draw more than half an amp at best. My strategy is you keep the fancy electronic stuff that draws low amperage and doesn't like to be on a dimmed ciricuit on Edison plugs. If anything has a high amperage draw you put a stage pin connector on it. That makes it REALLY hard to screw up.
I finally got all the Seachangers running tonight. It was amazing to see them. While the fuller saturated colors are pretty good, I'm most excited about how well they duplicate the lighter saturation colors. Combined with the gel book inventory in my Strand console, you click a button and boom you've got R51, R02, R33... all those lighter colors look great. (Even Derek's favorite: Chocolate).
Only negative so far is that they are a bit of a pain to manipulate in the yoke. I purchased the optional yoke extensions which are really a must... the longer instrument means you are extremely limited in how much you can move a standard yoke. Unfortunately even with the longer yoke there still are some issues with positioning. Nothing impossible to live with, just things to make your life a little more difficult.
