unfortunately I find that when using this with an expression pedal between rehearsal and home, that the connection seems at time to be lost (then with a little wiggle of the connection, it comes back). this is then not reliable for live use. PS: i do not seem to have this issue with the connections that are fixed and not being regularly taken in and out as with the expression pedal.
One more issue, the end of the cable seems to come off rather easiliy - happened 2x with separate cables bought in two separate orders.
Overall this is not reliable or professional, or I have been too many times too unluck with them to trust it. Therefore a great idea and design but it must first of all work reliably, and that is simply not my experience. Can not recommend it to a gigging musician.
