Saw that in my email last night. Might use in on my next custom build! Looks very interesting to me.
I'm thinking of putting that in my Les Paul to experiment with different caps and pot values.
I recently installed a Seymour Duncan liberator system on one of my guitars so I could try out a whole bunch of pick ups, and thought, all I really need is the patchbay portion, this doesn't need to be on the volume pot. These guys are giving you just that, and took it to the next level!
All that being said, once I decided on pick ups I took the system out and soldered everything direct. I think it's a great way to try out a bunch of configurations, but at the end of the day I'm just more comfortable going old school.
It's to let you experiment with different ways of wiring up your guitar without having to fire up your soldering iron every time you want to make a change. You can leave it under the hood as long as you like.I don't get the concept of that tool. Is it to connect one position at a time only and to try only that one? Or is it to rearange the whole wiring of a guitar forever, so it stays built in under the hood?
