Yes - in stereo; a pair of them.

The Pod HD outputs are Line level; no need to worry about a Line/Amp switch.

The Pod HD 1/4" outputs are a stereo pair. If you connect only one of the pair to the L3t 1/4" input then your L3t is receiving half the stereo signal. Use both 1/4" outputs from the HD, and connect them to the L3t RCA stereo inputs. That way your L3t will receive the full signal, even though you will hear it in mono because there is only one L3t.

The HD500 has a physical switch labeled Line/Amp on either the back or top of the device. Set the switch to Line. Use the Stereo RCA inputs on the rear panel of the L3t. This will require you to use adapters on your audio cables, or get a pair that have different ends. The HD500 end is 1/4" and the L3t end is RCA.

Glad it's not a problem for you, and it may help those who are in the practice of just clicking 'yes' to save time rather than actually reading and thinking about warning messages.

Actually at that point I think it is a 'may lose' situation. After that warning message and during the update process you are presented with an option to keep or discard your existing presets. That's where it turns into a 'will lose' situation if you select to discard them.

Why would you think they were kidding? That's what the warning is for. Neglecting to back up set lists and/or presets before updating firmware is simply asking for trouble.

No - I'm saying that this can be done. It's just not what I would call using the HD500 for re-amping. I would call it using the HD500 as a reverse DI-box, or something like that. Here's a preset I constructed long ago that allows you to simultaneously record both wet and dry signal from the HD500 to a DAW: http://line6.com/customtone/tone/217206

I would recommend that everyone make a backup before updating firmware. Then, during the firmware update process, choose to replace all presets.

That's great. As long as you are happy with your X3 tones there's absolutely no reason to change. Happiness is not getting what you want - it's wanting what you've got.

Right you are... sorry for any confusion, and thanks for the correction.

The problem is you no longer have your X3. One solution is to get another one. A better solution is to start using your HD500x. Even if you could see all settings in your X3 presets, you won't be able to manually recreate those sounds in the HD500x using those exact preset/parameter settings. Firstly, many of the X3 amps are not available in the Pod HD. Secondly, the FX modeling technology is totally different; the HD uses the Line 6 M-series FX while the X3 does not. So even the same FX models will sound different with all parameters set the same. Thirdly, the same is true of the amps; the HD uses completely different amp modeling technology so the same amp models (where they exist between the X3 and HD) will sound different with the same parameter settings. Finally, and most importantly, the Pod HD offers far superior sounds to the X3. You are doing yourself a disservice if your goal is to simply recreate the same sounds you had in your X3. If you simply wanted to keep, or recreate, your X3 sounds you would not have upgraded. You upgraded because you want, and can certainly achieve, better sounds. But the way to do is is not with your X3 presets. So forget about the supposed problem you are facing. It's not a problem. Learn to use your HD500x - that's where your energy should be going.

Yes. Any audio cable will do. Generally speaking, avoid the really cheap ones.

That requires an update to the Workbench HD program, not (or at least not only) the POD.

I would connect the HD 1/4" outputs to the Line In inputs on the rear panel of the L3t. Set the POD HD output mode to studio/direct, and the switch to Line. Set the L3t to Reference mode.

Three possibilities: the cable, the VDI jack on the JTV, or the VDI jack on the HD500x. Try to narrow it down. The cable can be tested by using a standard RJ-45 (Ethernet) cable temporarily; just be careful with it due to lack of protective shields at the cable ends. As for testing the device VDI jacks - do you have access to other JTV or Pod HD devices?

The POD HD has no L6 Link output, and this update targets L6 Link functionality almost exclusively. The HD pro/x specific fixes also do not apply to the Desktop device.

Try using the HD500 'PRE' (not FULL) amp models. The difference is that the pre amp models exclude the cab and mic modelling that is used in the full amp models. This difference is important when routing output to a guitar amp, which applies it's own cab - and mic as required for stage/recording. Also try using one of the Live output modes - select the one that most closely matches your amp. Try setting the output switch to Amp. There's no right or wrong here. As was already mentioned, studio/direct mode can give good results too. Trust your ears. You might also investigate the four cable method. Search this forum under 4CM.

You can do that. Set the Hd500 output to amp for the correct signal level as you suggest. The DAW playback will be routed to your amp input. I just don't understand what that has to do with reamping. You can't select the USB stream from the DAW as an input for processing with the HD500, and if you plan to record the mic'd amp output using the HD500 mic input you will likely encounter a feedback loop within the HD500 that defeats the purpose. Give it a try, but be careful with your levels.

No, this won't work either. Gearbox does not open or load tones without the X3 connected.

I'm almost certain that the octaver will adjust all notes; you can't assign it to drop only the lowest note. You could check it out by researching the original bass octaver device that is being modeled. Line 6 generally models the devices pretty accurately. If the original device does not have the feature you describe, nor will the Line 6 model.

Sorry to hear that. If your jtv59 is no longer under warranty it might be cheaper and faster to take it for repair to your local guitar repair centre. I don't expect that the toggle switch itself is unusual and it could be a straightforward fix. You might want to ask Line 6 if it's a special switch on some way.

I suggest you open a support ticket to work directly with Line 6 on this.

Here perhaps is some info for your consideration re: the lack of response to your post. I noticed your thread today for the first time, and opened it. The sheer length of the first post dissuaded me from reading it in case the issue was already answered, so I scanned down further. I notice several additional posts by you with further detailed info and about a dozen relevant mp3 files. I estimated that it would take me at least 30 minutes, probably longer, to thoroughly read, assess, and determine whether or not I have anything to offer. Then further time spent on composing a meaningful response. I can't do that right now, and likely never will have that kind of time to spend on a single post. So I thought I'd at least tell you why I am not responding. If you can possibly start a new thread, and be short and concise about your problem, perhaps more readers will spend their time considering it. Please don't take this the wrong way; it's offered in a spirit of helpfulness.
