I'm still waiting to receive the wiring loom from support so I can get my tuner working. I've had it for some time now and I have never seen it work yet.
I wouldn't mind having some confirmation from someone at empeg who frequents the BBS that this would be the correct action considering the facts I've presented. I don't want to bring up another issue until the first one is resolved, especially if they're just going to tell me that I'm out of warranty or something.

Sending my whole unit and tuner in is what support recommended when I emailed them about my tuner not working. Thanks to Q/A on the BBS, I didn't have to, they just sent me a new loom. Now, it just has to get to me.
