I recently had the desire to be able to use my steels, both lap and pedal, with my pedal board and optionally place a volume pedal between the timbre and ambience effects. For example, distortion and rotary effects between the steel and volume pedal and reverb and echo after it. I wanted to be able to remove the volume pedal and have it act like a regular effects chain. I'm pleased with my solution and would like to share it with the forum. Here is how the following circuit acts:

With any two jacks plugged in the circuit just acts like a wire. With any three jacks plugged in the circuit acts like a signal splitter/joiner although I didn't make any effort to provide impedence correction. Finally with all four jacks plugged in the box acts a break out box where each jack's signal goes through to the single jack on the opposite side. This allows a volume pedal to be inserted into the effects chain. It could also be used to split a single pre-input pedal board into pre-input and effects loop sections without changing the board wiring . Additionally, it allows the volume pedal to be placed in a convenient location away from the pedals.

I used a Bud Industries C11 CU-123 project box which provides a very small 3.5 X 1.375 X 1.25 unit. Using high quality Switchcraft jacks and buying at the local retail electronics store it cost under $25.00.

Maybe someone will find this idea useful, I've never seen anything quite like it before. Questions, comments and observations are welcome.
