I don’t do any offboard wiring anymore. When you really get down to it, it’s a big time sink.
I have a very good process FOR doing it, but you are still prepping/tinning wires, positioning everything, etc. and that takes time.
One reason I went to a modular approach with PCB mounted I/O DC was so that I could remove the whole circuit without having to desolder.
I haven’t sold enough to have gotten any warranty repairs yet but you need to sneak that shit it between builds and I can’t be fucking around with offboard wires.
