I planned to use this for wired IEM, having a combined guitar cable and IEM line signal. However, while the cable is pretty thick, most of this comes from the outside rubber. The both wires inside are pretty thin compared to other guitar and line cables. These would probably work fine, but especially the line cable seemed too thin for strain relief in XLR connectors. In the end I ended up wrapping a regular guitar cable and SC-Goblin in a shrink tube instead, and I’m happy with that decision. This seems like a good cable otherwise, just not for the purpose I had in mind.
