AHHHHHHHH OCD overload, fix those wires!!!! giving me a panic attack. I have a wire obsession. I spend way to much time on wires usually.
Really though if it works leave it. When I was testing the first one, the first few rebuilds I resoldered the wires every single time, then came the solderless mounts, then the wiring harness. Now is takes an hour or so to do what used to take a full day.
