Guitar Centre is somewhat notorious for recycling used/damaged units as new. I think your hypothesis is probably accurate, except that I doubt Line 6 was involved.

Reinstalling the firmware will restore factory settings. Make sure to back up your existing presets/setlists first, and choose 'No' during the update process when asked if you want to keep your existing presets. After reinstalling, you can save each factory setlist for future use in case you ever want to do something like this again. Alternatively, perhaps someone who saved the factory setlist called 'Best of...' can post it here for your convenience. But rather than wait you can do the above.

Yes. And make sure you keep the paths seperate if you want independent processing.

Here is a preset that gives you the basic setup. Tweak as desired in terms of FX, but keep the overall dual path structure the same. http://line6.com/customtone/tone/215659/

You should be able to connect the speakers to the Headphone output jack on the UX2. You may need an adapter.

I have to agree with Phil, based on my personal experience. I took a Variax 300 to my regular guitar tech/luthier who was completely unfamiliar with Variax guitars. There were two goals for the job: to replace the full set of piezos, and to diagnose and repair an electrical problem. We had agreed on a price range in advance based on his confidence that he would be able to learn enough about the instrument to complete both repairs successfully. He ended up spending W-A-A-Y more time than expected on each part of the job, and in the end the electrical problem was never diagnosed and fixed. To his credit he honoured our agreement - and lost some money. So, for the benefit of both you and your client, an authorized service centre is the best option here.

I suggest you open a support ticket. http://line6.com/support/tickets/add.html

The best way to monitor your sound is to use the HD500 outputs; it becomes your computer's soundcard when connected via usb. If your PC speakers can be connected to the HD500 headphones output (maybe need an adapter) that would get you started. While it is possible to do what you ask it is not recommended and will yield relatively poor sound quality. A pair of studio monitors will give you much better results, but you may want to wait a bit to make that decision. Have fun!

I find it useful for practicing/creating solos as well as for tone building, but I too gave up on it for live use.

It depends on where the USB connection is. The POD HD ProX must use its MIDI ports, not its USB port for MIDI communications. So if your usb/midi controller connects to your computer via USB and to the Pod via MIDI, then it should work. But if your controller needs to use USB to connect to the Pod then it won't work.

Check out the M5 Pilot's Guide (page 8 - section titled MIDI Control). http://line6.com/data/6/0a06434d12155507f39d011ad3/application/pdf/M5%20Pilot%27s%20Handbook%20-%20English%20(%20Rev%20B%20).pdf

Unfortunately that can't be done. The POD HD Looper has no concept of tempo/time; there are no beats, no metronome and hence no possibility of synchronicity. It operates on a simple start/stop switch. It starts recording the instant you push the footswitch, and it stops similarly. It records everything in between. It's up to you to keep the tempo of your playing consistent while recording, and also to start/stop the recording at exactly the right 'beat' according to your concept of tempo - without any silence at the beginning and end of your recording interval.

Two very important things for a music/recording PC: lots of RAM and a quiet fan. The processor speed is not likely to be an issue, but too little RAM will cause problems. And fan noise can make its way into your recordings especially when using a mic input. For best performance when recording, disconnect your computer from the Internet and temporarily disable all unnecessary background processes such as virus checkers, spyware, and other usb devices. You can still use USB from the HD Pro to your computer, but make sure you get at least a couple of the older USB 2.0 ports rather than exclusively the newer USB 3.0.

Firmware adds SPP bluetooth capability for data communication with Android devices. This update is NOT required for iOS users, but will require version 2.00 of the iOS app as device names have changed.

Yes, they would have a problem. It's intellectual property. (see my post #2 above)

POD HD500/500x/HD/HD Pro: You must re-install the flash memory on the device to reset the unit back to factory settings. Check out this link for instructions http://line6.com/support/page/articles/_/effects/pod/pod-hd/video-tutorial-how-to-reset-the-pod-hd-series-r209

If you select the amp in the signal chain view then hold down the ENTER key you will get to a display of all the amp's tone stack settings. You can also do this with each of the FX to see their settings. As an alternative to taking a kazillion photos I would consider building a quick Excel or Word table to manually record all settings while viewing them as described above.

http://line6.com/account/registergear/ The above page will let you remove your KB37 from your list of registered devices. The new owner will then be able to register it to their account.

The L2 speaker mode is a global setting. It applies to all inputs. You can't have your vocal output remain in PA/Reference mode while your HD500X preset changes the mode to Electric Guitar.

There is no way to transfer tones from the HD500 to a HD Pro without using a usb connection on the HD500 to get the tones to your computer using HD500 Edit. Unless you have previously saved your HD500 presets/setlists to your computer while the USB connection was working, you will need to recreate from memory your customized HD500 tones manually on your HD Pro. I have had the USB connector on my HD500 repaired. I can't recall offhand the exact amount but I know it was more than $100. It is not a simple matter of replacing the port itself; there's an internal hardware component/chip that also needs to be replaced.

Correct. I see now that your original post requesting a refund was not serious. I often try to return a meal in restaurants after I've finished eating it. They don't allow that either.

You will need to return the device to the store where you bought it. Their return/refund policy will determine your options.

Here is a what Google tells me about the PNY Premuim cards: http://www.walmart.com/ip/PNY-2GB-Premium-Secure-Digital-Memory-Card/11078643 Note that it is a Class 4 card. You need a Class 10 like this: http://www.walmart.com/ip/PNY-16GB-SDHC-Card-Class-10/34313262?action=product_interest&action_type=title&placement_id=irs_bottom&strategy=SMT&visitor_id=29210023318&category=0%3A3944%3A133277%3A132913%3A63988&client_guid=f93e43d7-321f-48a1-ac12-b102bf30b967&config_id=0&parent_item_id=11078643&guid=9a3a6b66-b811-491c-94c6-5987decc3f37&bucket_id=irsbucketdefault&findingMethod=p13n Note the High Performance (aka high speed) designation.

Open a support ticket to work directlywith Line 6 on this. http://line6.com/support/tickets/add.html

Check your Input settings on the POD for the preset you are using. Not sure why you want to use the Mic rather than Guitar input, but you need to assign the physical input to either Input1 or Input2 in the preset.
