One thing you didn't mention - have you run Line 6 Monkey to guide you through the download and installation of the Line 6 usb driver?

Yes - just connect them as you would normally. Run the Main Outs to your sub, then connect the 2xL2t using the XLR rather than L6 LINK connections.

Sounds like you've already done some good troubleshooting and eliminated the usual suspects. There may indeed be a hardware problem with your Pod. Since it's the HD500x it is certainly still under warranty. I would open a support ticket to work directly with Line 6 to get it repaired, or otherwise restored to working order. http://line6.com/support/tickets/

Make sure your GX device is registered, complete/update your user profile here, then open a support ticket to work directly with Line 6 on this. http://line6.com/support/tickets/add.html

Run Line 6 Monkey with your gx connected. A Pod Farm license is associated with your gx and will be available to you as the new owner. Monkey will help you download and install the version associated with your license. Then run the Line 6 License Manager to activate your license and authorize your equipment.

Are you running the latest X3L driver? Driver v7.3.6 added support for Mavericks.

Let Monkey do all the work for you. Just install the latest update - it includes all previous updates. There are no expansion packs - everything's included at no additional cost. License Manager is not necessary in order to use/update the HD500; registration is recommended but not required. However, registration will be required if you ever need tech support or servicing.

Have you run the Line 6 License Manager to authorize your computer? If not you may only be able to use Pod Farm in demo mode, which severely restricts the available number of amps and FX.

It's a software program like any other on your computer. Use the normal uninstall procedures.

To get Vyzex, go here http://line6.com/software/ In the middle panel where it says All Software scroll down to the bottom and select the Vyzex Editor.

Here's a sample preset that provides separate, independent signal processing for your guitar and mic. Tweak to taste - but don't place any amp/fx in front of the path split. http://line6.com/customtone/tone/215659

It is quite common for usb ports to behave differently. Line 6 devices require USB 2.0 ports, and generally don't behave well with usb hubs. Many PCs have internal hubs that serve multiple usb ports. You want to try to avoid that.

Yes - reinstall firmware. Save your presets first and choose NOT to keep existing presets when prompted during firmware installation.

I would open a support ticket to work directly with Line 6 on this. http://line6.com/support/tickets/add.html If your guitar was under warranty when you first took it in for repair to the line 6 shop, you are entitled to have the problem resolved. If your local shop can't do it, it is Line 6's obligation to arrange to have it fixed properly or replaced. If it's not under warranty you will have to pay for the proper repairs.

A single studio monitor is fine for your purposes. Make sure you feed it with a summed mono signal from the HD500 output; that means the L/MONO 1/4" output rather than one of the XLR outputs. Also, placing it on the floor will add a 'boomy' sound emphasizing the low end. If you don't like that you can raise it off the floor somehow. Also be aware that you will hear a different sound from the monitor than you do from your headphones. This is normal, and due to the different characteristics of the devices. You may find you want to maintain two sets of differently EQ'd presets; one for headphones and one for the monitor.

Here is a preset I put together some time ago to do what you want. Just customize to suit for electric guitar. http://line6.com/customtone/tone/215659

I presume you have used Line 6 Monkey to ensure that your UX1 driver and Pod Farm software are up to date?

Yes. After installing Pod Farm on each computer you want authorized, connect your UX2, register your gear and update using Monkey. Then run the License Manager on each computer before the first use of Pod Farm.

The looper on the HD50 is a great tool for practicing solos over a backing chord sequence, and is also great for auditioning and tweaking tones to hear the changes in real-time without having to stop playing to tweak. It is not so good as a real-time looper in a performance/live situation.

Can't help with your 48v question, but I can tell you that the M20d is not a good audio interface for general recording purposes using a DAW. The latency is just too high; synchronizing overdubs or additional tracks to the original recording is very troublesome. Switching to Ableton won't help.

I believe that if you zip the setlist file you will be able to attach it to a post in this thread. Then interested readers can download and unzip it.

.... thought you said in your initial post that you didn't want a bitchfest......... Line 6 is not going to answer you. Anything else is pointless speculation. Let the bitching continue...........

You can use it on multiple computers. Run the License Manager to authorize your different computers.

If you still have your X3 you can connect it, run gearbox, and view the tone details. Simultaneously you can run HD500x Edit without theHD500x connected and recreate the tones manually. They won't sound the same, and you'll have to make your own trials in terms of similar sounding amps that the X3 has and the HD doesn't but it's a starting point for tweaking. Then you can save the HD presets as files to your computer and send them to your HD device when you connect it later.

I think Phil and I are interpreting this question differently, based on what you mean by a workbench preset. The pod has no concept of things like guitar body, pickup styles, etc. that you can adjust using workbench. You can't select or modify those things using a pod. All it can do is tell the Variax which bank on the knob to select, and the few other things described above. With the original Variax ALL you can do with a pod is bank/knob selection. With a pod HD and a JTV you can also specify alternate turnings and knob controllers. That's all. The pod is not an alternative to workbench in terms of building Variax models, if that's what you are hoping.
