I’m going to be using octave and chorus pedals for a gig next weekend, so I set up the entire chain with my tuner last night. While playing, I realized I was getting substantial tone suck. Careful troubleshooting (I’m an electronics tech and structured cabling designer) narrowed it down to my short patch cords. 3 out of 4 noticeably attenuate higher frequencies when tested directly between bass and amp. These cables all pass a continuity test and I can’t see any resistance with a meter at its lowest settings. I suspect they must have been crushed at some point. Most surprising is a Digiflex cable with Neutrik ends. Does anyone know of a practical way to test for quality besides comparing them by listening?
