Before I bother my luthier with this, is there any way I can fix this on my own? Tape? Some of those 3M cable routing things?

Thanks in advance for any advice.
Depends on how you installed it. If you have access to removing the jack you can tie a loose loop in the wire to take up slack. I put an acoustic feather in my F many years ago and was very careful with the installation. It's worked flawlessly for many years when amplification is required.
