So I guess wishing I had a TDR handy to troubleshoot a guitar cable would count as overkill or something, huh?
It sure would be convenient though.
Now there's an instrument where, having ever used it, one never stops seeing situations where it would come in handy. Gosh, that was an awfully long time ago. (Not counting the time a neurologist used the-same-thing-with-a-different-name on my nerves, which was also quite a while ago now, come to think of it.)
