That connection eliminates the small voltage spike while the Crack warms up if no headphones are plugged in.

interesting. I assume that voltage spike is not good, therefore I guess I shouldn't remove that little wire. right? What's the downside?

To be honest, the voltage spike isn't a problem.  When we put out the first iteration of the Crack, we encountered endless threads about the voltage spike, so when we revised the kit I altered the design to make it a non-issue.

As a preamp, the coupling caps in the Crack are kinda big, but if you turn your amp on last, you're not going to have any problems.
