I've had a Dream Rig consisting of a JTV-59, L3t, and a POD HD500 for about 2 years now. I've noticed that in the past 2 years I've had about maybe 2-3 instances where I would get either no sound from the JTV-59 or no response from the POD HD500 when I would change presets. Normally I would power the everything up in a certain order starting with the POD HD500, then the L3t, then I would connect the JTV-59. On occasion, I power up the L3t then the POD HD500 and then connect the JTV-59. I have the POD HD500 and the L3t connected via L6 link. I'm beginning to think that when I power up in a different order I get the issues I'm referring to. The latest issue occurred a couple of days ago when I connected the JTV-59 first to the POD HD500 then I powered on the POD, then I powered on the L3t. I didn't get any power to the JTV-59 at all when I did this. I had to shut everything down and power up the normal way I power up and everything was fine. Anyone experience anything like this? I also have the USB connected as well. Let me know if you guys can test this out if possible. I'd like to get some feedback.
