Rich, It seems you have some problems in your customer service department. I have an XDR95 unit and the transmitter has gone bad. I borrowed a friend's transmitter and isolated the problem to the transmitter itself. Mar 21: I post on the online support forums asking for repair options and am told to contact Line6 for an RMA. Apr 2: I call in and explain my troubleshooting. Even though I've registered my gear online, I am told I must submit proof of purchase. Apr 14: It takes me some time to track proof of purchase down and email in a copy of my order confirmation. (Purchased online) Emailed to email@example.com as instructed. April 22: After no response, I forward the email again. April 23: I follow up with a phone call and go through the diagnostics process yet again. I ask why my email has not been answered and the young lady tells me she is new and her email is not working. ??? Your main support email address is not working ??? I spoke with the same lady on the first call, so she's been there since the first of the month... and her email isn't working.... April 25: I email all the documentation and reference materials yet again to firstname.lastname@example.org. April 26: (Today). I get an email response that a ticket has been opened and the link references a ticket number. Unfortunately, the link provided in the email is broken. So I log in to my Line6 account and look under Support Tickets. No ticket exists. I'm at over a month now trying to get customer service and I am told turnaround is two weeks. So six weeks (or more) trying to get a replacement transmitter. I have not opened the pack, but I'm betting it is just a broken wire. I could have that fixed in the time it is taking me to write this thread. However, if it is something more circuit board related, I don't want to hose myself by voiding the warranty. I'm not holding out hope at this point, but will call in tomorrow and see if your customer service department can get this resolved. Rich, this is a real problem and bears investigation. Please let us know what you find out and what corrective actions are taken.
