Had a strange problem recently...
Rig volume dropped while playing live. Moved one of the coiled, 25' cables and output returned. Went straight into the amp (DSL40C) for the rest of the set.
Came home and could not find a problem with the cable. Everything checked out.
All of my cables are Monoprice Dual-Path (2 jacketed conductors covered with 2 ground braids) with gold plated, rebuildable ends...except two...which are Musician's Fiend house brand.
I had laid the coiled section of one of the 25' MF cables on top of the Origin 50H, and it created the loudest buzz/hum i can describe.
Move the other cables to the top of the head - no noise.
Something in that cable appears to have begun to fail internally - in the middle of the cable - which allowed the cable go.pick up and transmit the OT's magnetic field.
I immediately replaced the pair of 25' MF's with new Monoprice dual paths.
Only one studio I work at uses Mogami. All the other studios use Monoprice cables and they are some of the best cables i have ever used.
Out of curiosity, has any had a cable issue like this one???
