It is if the VOLUME pedal is at the front of the chain before the amp.

Sorry I didn't answer your second question.  Assuming the VOLUME pedal is only controlling volume and is not assigned as a controller to adjust the DRIVE of the amp model, then you can simply place the VOLUME pedal after the amp to control overall volume level without effecting gain/drive into the amp.

On a factory set HD500X you will get the supplied Line 6 Set Lists along with at least 2 USER SET LISTS at latest firmware level - but if it's the previous firmware level you will get 3 USER Set Lists.  The User Set Lists consist of BLANK new patches with nothing in them.   You use one of those patches to create your own and test things out.
 
If you buy your own one, then one of the first things you should do is backup all the supplied patches, and then backup one of the Blank user set lists and one of the blank user patches which you can then use to reset things as and when needed.

The new fw requires a global reset and that reset changes the default tuner mode to bypass so all you need to do is reset that value to mute. When tuner is activated, control knob 2 allows you to change between bypass and mute, and the value is displayed on the screen below the tuner display.

If you are using the unit standalone (ie: not connected to PC with HD500X Edit active) - then when you change a parameter it will take immediate affect - however it will not be permanent until you physically SAVE the patch by pressing the save button and confirming you want to save it.   Once you have done that then it should consistently return to the settings that you last SAVEd.
 
If you are using the unit connected to PC with HD500X active, then ensure you NEVER touch the physical controls or pedal on the unit - only adjust the values using HD500X EDIT - then when you are happy with you changes make sure you SAVE the patch by sending it back to the unit and wait for a few seconds to allow it to write the patch back to the units flash memory.  Once you have done that then the unit should consistently recall the settings you last SAVEd.
 
If you want to recall original settings or previous saved versions of patches then you can only do that if you backup your patch list when connected to HD500X EDIT.  Obviously if you don't save the patch the original settings will be retained and can be recalled by re-selecting the patch. Once you have a backup then you can recall previous saved patches when you want.
 
You can restore original factory settings on the unit by manually re-initializing it if necessary but you can't manually recall a previous patch if it has been overwritten unless you first saved a backup on your PC via HD500X edit.

The POD converts the guitar signal to digital and then back to analog and with no fx or amp sims selected will lose about 6db of the signal strength - so comparing it to a guitar going direct in to an amp - it will sound quieter and therefore weaker and thinner.  The first thing you need to do is select an output mode and stick with it and then adjust the straight through guitar signal so it sounds the same as when the guitar goes direct.  This will usually involve using an fx block for an EQ fx or the VIntage PRE fx and boosting the signal - or just boosting the signal at the mixer block.  Try this with each output mode and see which you prefer and then stick with that and tweak it.  Remember the output modes are effectively just applying a master EQ curve to the final output to adjust for whatever amplification you are using. The COMBO and STACK FRONT settings allow you to tweak that EQ curve as they provide controls for high, low and mid focus, which will help when going straight into an amp by allowing you to compensate for the amps own pre-amp.  If you go in via the amps fx return or directly into the amps power amp then you should be fine with the other COMBO/STACK settings or STUDIO DIRECT.   Remember that STUDIO/DIRECT will include the cab's mic and air simulation if an amp/cab combo is selected - in other words you will get a mic'd up amp sound going into the amp rather than a direct guitar signal - so it will sound different - but if you are not using the amp or cab sims then it should not make any difference to you - so experiment and find whatever setting suits you best.
 
Also check the setting of the slider switch next to the foot pedal marked 1/4 out - set it to AMP if going into the input jack on a front of an amp which will ensure the POD output matches instrument level and won't overdrive the input of the amp - but if you are going into the power amp or fx return you may need to switch it to LINE to boost the output signal t the correct level for the input chosen on the amp.

They are exactly the problems of the original pick up switch issue - which is why they upgraded the switch and swapped the switch on all the early models.   Sounds like you just need to switch replaced with the new version - perhaps your guitar was old original stock - contact Line 6 support and they will sort it for you - especially as its within its first year warranty  - they can tell from the serial number and the switch itself if it was an original.  

The popping sound has been fixed by JTV fw 2.1              :)
 
The behaviour of the model selector switch on the JTV when connected via VDI to HD500 has also changed under fw 2.1 to now match the behaviour I reported at top of this post.  
 
This has been confirmed in this new thread: http://line6.com/support/topic/7326-have-you-noticed-changes-on-pickup-selector-switch-and-model-selector/

This is fixed with JTV fw 2.1
 
:)

This has been fixed at JTV FW 2.1.
 
Great news!
 
This thread is no longer needed!    :)

The modelling software is identical on all JTVs - 59, 69, 89 - and all variations.   The factory supplied default alternate tune settings are the same on 59 and 69 but the 89 has a different set more suitable for "heavy rock" style players, plus the 89 does also have access to a model copy of it's own on-board mag p-ups, so you can apply the alternate tuning programming to them.
 
The 3 guitar styles are obviously different and will therefore have an affect on exactly how you play them and also the physical differences may introduce subtle variations in how the model sounds get rendered, but I think you would have to have an extremely fine tuned ear to be able to differentiate between a LESTER BRIDGE model being played on a 59, 69 or 89.   I would think that most people would not be able to tell the difference.
 
As brue58ski pointed out, the main thing is to choose the guitar with the physical characteristics that suit your playing style best, because each of them have different shaped necks (chunky, slim), different nut widths, different scale lengths, different numbers of frets, and different access to the higher frets.   Also whether or not you want a trem - then that limits your choice to a 69 or an 89F.  If you want a fixed bridge then you can only go for a 59 or an 89.  If you want a slim fast neck then it's only the 89.  If you want a vintage chunky neck with narrow width nut then it's the 69.   One other important thing to point out is that if you go for a 69 you can easily swap out the neck to one with a profile and radius that exactly matches your preference, essentially any neck that will fit a standard FENDER pocket can be used. If you want a FENDER scale length then it has to be a 69 or an 89, if you want a GIBSON scale length then it has to be the 59, etc etc..  So, make your choice based on your preferences for the physical attributes of the guitar and what style of music you will be playing, and rest assured that the modelling available will be the same with the one exception I noted above regarding the 89 pickups model.
 
Hope that helps.

In the HD500 driver control panel there is an option to add an 18db boost - by default that is NOT checked.
Try checking that box and seeing if it resolves the issue for you.  You may also need to adjust the other settings in the control panel to compensate for the boost.
 
I don't have ABLETON so I can't describe how you navigate to the driver control panel for the HD500 - maybe it's under PREFERENCEs or OPTIONs or whatever the ABLETON equivalent is.

Are you using INPUT 1 set to VARIAX and INPUT 2 set to SAME?   If you are, then simply changing INPUT 2 to GUITAR for patches where you only use the Variax will lower the input by 6db.
If you are already doing that, and you don't wish to adjust string volumes on the Variax with workbench, then you can use an fx block as the first in the chain to attenuate the input. The Vintage PRE in the EQ menu will allow you to lower the gain and some of the other EQ fx can perform a similar function.

I bought a DT25 cover from ROQSOLID who are based in the UK - they are very good. Quick service and good hard wearing heavy duty covers.  You can ask them to make custom made covers just by providing dimensions or you can buy one of their ready made ones for popular amps - and they cover the Line6 range.
 
Their website is here: http://www.roqsolid.co.uk/wp/
 
But you order your amp covers from here:  http://www.amplifiercoversonline.com/zencart/index.php
 
And I did a search for DT50 and they do provide ready made one covers for DT50 range including 212: http://amplifiercoversonline.com/zencart/index.php?main_page=advanced_search_result&search_in_description=1&zenid=14fbup42bt1hicqiuuqs8tadu6&keyword=DT50&x=32&y=6
