Chony,

I've been thinking about a solution to your problem and came up with this. Assuming that you use the same setup each time, create a complete, cable harness for each of your setups. One for when it's just you performing, one for the trio, and one for the larger group. This would eliminate a lot of problems, and eliminate wire clutter on stage. Additionally, your setup time would be dramatically reduced. Granted, it will likely take about a day to create the three harnesses, but benefits in time saved, storage problems, stage clutter, etc.., would far offset the time and expense.

Just a suggestion,

Gary
