I'm getting a signal loss from my patches....where should I look first?

[liddokun]

I'm making some short patches for my pedalboard. Here's the problem, from all the ones I made, except for one, there a volume loss. Probably less definition too, but volume is way more noticeable. I tried each one directly into my amp, only one of my patches doesnt have the issue. Also, I checked for continuity, everything is ok, and resistance across each one was .2ohms.  I made each patch with the same type of cable, and no, it does not have that second shielding layer that is semi conductive. It's just outside insulation, ground/shield, insulation, hot signal wire.  Any clue as to what my problem is?

i would take them all apart take all the solder off that you can then redo them all. fi it continues to happen send them back to the company or write untill you get some kind of answer or free product.

  The only tests a DMM can do is continuity / non-continuity.
  Close-in light and mag-glass may help.
  They'll get messy the more you mess with 'em.
  The better test is take at least 1 best good cable, put it between guitar and amp, then use that as a reference sound, noting especially the treble [as that tends to get lost most easily] and searching for losses...get as much signal as you can into the amp [with good, short stout cable], try to get as good after all the other patches.
  There is no easy to sort cables, one at a time may help, the losses tend to add though.
  10' fine cable from guitar to PB, then impedance boost through the other numerous patches, low impedance output often drives the 20' cable to the amp, high quality here too.
  5 of 5 cables I bought from GC, the only 6'' angle plug patch cables int he store, [desk-bin, black with hex-ish plug casings], I barely got continuity from one of them, they're all tone chomperz. The RS 12'' angle plug patch cables I'm testing seem to perform great !
  I gave up on cable building after I ran out of Belden Shielded Cable, and had similar luck a buncha times...
  That said, the cable wire-insulation-shielding type and quality may be determinable.
  Getting nice joints with light duty soldering equipment seemed to be difficult or damaging, I constructed a holder jig involving a 1/4'' jack..whipped out my industrial 'club'-solder-er, made quick-sure job of it by pre-tinning, then pinning the wire down after soldering [since I can never get it neat-stranded, on, and flat-ish seemed to keep the insulators a touch cooler.
  The only real recommend in all this is don't get the GC 6'' angle patch.
  OT:
  A less adaptable, more reliable method is hardwire it all into a larger enclosure, but having the adaptability to test out chain orders helps to figure out the order of the hardwired unit.
