I know this happened to others earlier on while the Remotes were just arriving.
Well. It just happened to me!
That pesky little Cat 5 retainer "nib" just broke off an otherwise perfectly good cable to the Remote.
I searched for replacement cables.
Yeah, they're certainly available but way too pricey to justify getting now when mine works fine. It just has the risk of falling out.
What really bugs me is I'm real careful with my equipment. Plus everything else regarding Kemper gear is so quality driven.
To fix, I thought about lopping off the end and re-crimping a replacement.
But rather than investing in a crimp tool and some quality shielded connectors, I decided to save some brain cells and purchased some RJ45 SOS modular connectors. http://www.ebay.com/itm/122009459728
After seeing these, they did the trick and with a 10 pk, no more worries about getting stuck any time soon.
Moreover, I really didn't want to mess with an already sound wired connection, so these little buggers saved me loads of needless anxiety.
FWIW - I also now use a simple 10' ethernet cable with snag resisters for practice preferring use of the repaired cable for performances.
Hope it helps someone.
