Super nice board OP! Very well done. I'm getting ready to do ll custom cables on mine too.
I'm not him, but...
I see that the connectors are neutrik but there is a box just above the interface that the connectors sit in- what is that?
There is no box they are sitting in other than the interface. The interface has a PowerCon input (where it's connected now) and a PowerCon output (on the right side with nothing connected at the moment)
The power cable comes out of the VL PP2+ with the standard IEC connection and rather than having the standard 3 prong connector the PowerCon was put on.
The PowerCon is connected to the interface box so all of the pedal board connections meet at one place. This way all of the connections that need to be made to the pedal board are in the same place. Connect your bass, connect you amp, hook up the power and you're done.
Can you explain the concept of the interface just a bit more.... I don't quite get what it does for you or what the link above would do for me....
Like I mentioned above, it's just a place for all of the connections to come together. It makes things nice and neat. OP obviously put a lot of thought into this board and a lot of time to make it a reality. I'm guessing that he also has a custom cable built that has power and audio connections built in so he only has one cable running along the floor back to his amp (totally speculation on my part, but I'd have it if I built this board)
The link to the Empress Buffer is a similar non custom solution. It doesn't feature the PowerCon, but you can connect your bass directly to it, your amp directly to it, your tuner directly to it, and use the built in loop for all of your pedals. All of your connection points in one place...
Bottom line is, if you don't think you "need" it you don't.
