Something sounds not right here... I have had no issues with the Helix tuner either playing at home or in the context of playing live and with a band. Is your guitar volume up? Are you going directly into the Helix from your guitar (no pedals or anything in between)?

POD Farm 2 has a more flexible signal chain than PF1. You can have up to 10 effects in a PF2 preset, and you can have multiple instances of the same effect if you want. PF1 gives you more of a fixed signal chain with the option to put the various slots in pre or post position. You also have the ability to use the individual effects as standalone plug-ins with PF2. If you wanted to use a certain reverb on a vocal, you can just use that instead of adding a whole additional instance of POD Farm.

If you just re-save the existing patch, your controller assignments will remain. You won't have to reset them in each patch.

Turning the model knob on the Variax unlocks the tone and volume knobs on the Variax, so they revert to their normal function. I guess the workaround right now is have a separate preset for each Variax model you're planning using.

Sounds like a hardware issue to me. If you haven't yet, open up a support ticket: http://line6.com/account/tickets/view

There is a battery for the EPROM in the Vetta. Sounds like yours is dead. Check out this thread from the old forums: http://line6.com/supportarchivenew/thread/26537/ It looks like it's not necessarily easy to replace it on your own. If you aren't comfortable messing with it, I'd contact a service center.

The receiver has to be plugged in to work. It's powered from the USB port (just like the other Relay receivers), so you could conceivably power it off of of one of those battery pack USB charging stations if you wanted a completely wireless solution.

Just and fyi, a ground lift doesn't disconnect the ground altogether. It inserts a small resistor into the circuit that increases the resistance enough to prevent small nuisance currents from flowing (stuff that causes hums), but if there was an actual fault, the current would be large enough that it would overcome the ground lift resistor. There is nothing unsafe about using a ground lift switch. What is unsafe is using the little adapters that turn a three prong plug into a two prong. This completely removes the ground. So, again, using a ground lift switch does not equal removing the ground. There shouldn't be any resistance (no pun intended :) ) to using the ground lift switch when necessary.

Is the phantom power for your channel on? That's most likely what's causing the issue. If the phantom power can't be turned off, use the Helix's 1/4" outs instead of the XLRs.

Do you have the phantom power on the M20d on? That's most likely the issue.

Sorry, but it's not clear to me from reading the first post in what configuration you're using the Helix when you're hearing the hum. What are you connected to and what outputs are you using when you hear it?

Pretty much the same... I am nearly the certain the switch is a mains switch, meaning it's cutting the 120V, or whatever primary voltage you're using, when it's flipped. So not really any difference. It's not like it's a relay that's initiating some sort of power down sequence. As soon you hit the switch, the Helix just turns off. It's not any different than just turning off a power strip or unplugging it.

Not that I disagree, but I find the Klon model works really well as a boost with low gain settings.

Assuming you're using a PC, you need to download and install the driver for the Amplifi in order to record with USB. It can be found here: http://line6.com/software/

I'm not familiar with Glenn's patches other than hearing them, but if you want to have a dirty amp turn on and have the clean one off at the same time, that's certainly doable. Sounds like you just need to change the behavior of that patch so it suits your needs a little better.

This is the expected behavior. There are three expression pedal controllers available - EXP1, EXP2 and EXP3. If you have no external pedals attached, the onboard pedal toggles between EXP1 and EXP2 by activating the toe switch. If you have a pedal plugged into the EXP2 jack, the onboard pedal will always be EXP1 and the external pedal will be EXP2.

So the issue is that all paths running through the Helix are stereo. You're not really losing stereo separation, it's that it's not acting like you're expecting with the path split there in path 2. I'm sure you're assuming that left would go to path 2A and right would go to path 2B. What's happening is that after the split, both 2A and 2B are receiving left and right output from those effects. To get a stereo split, you need to add a pan block from the volume/pan category before each of those preamp blocks. Pan the one hard left and the other hard right - you'll hear the split you want then.

Oh, I was thinking you were using the amp relay connection on the Helix to change channels on the JVM... Sorry. So does the JVM need one PC message to change to the gain channel and another to change back to clean?

Haha... Nope... I'm limited as to what I can disclose as I'm under and NDA with Line 6 (along with all the Expert Users here). The issues talked about in this post aren't anything new, and I can assure you that Line 6 isn't just ignoring them. I can't say anything else beyond that. My original response was simply an attempt to offer a possible solution that might work now.

Well, the gap between presets is something that every modeler on the market currently has. There are different scheme to do what you want to do. With the Helix, especially for effects-only like you're talking about, you should be able to accomplish what you want by switching between multiple paths in a preset (no tap dancing). You could control the output level of two paths by the same footswitch, and you could have the channel switching for your amp controlled by that same footswitch, so you could actually still do this all with one footswitch press. Also, though, doesn't the JVM itself have a slight audible gap when you change channels? I have seen other people mention that when talking about these amps.

No... The available DSP for a patch doesn't change based on whether the global EQ is on or not. That DSP is just always set aside for global EQ.

You need to program a CC to whatever the footswitch you want to use to control the H9's tempo. I assume you'll want to use the Helix's tap tempo switch since that means that whenever you tap a tempo in on the Helix, it will be sent to the H9 automatically. You'll have to set it up in every patch you use on the Helix, though. As far as how to do it on the Helix, you definitely don't want it as an instant command - it won't work that way. Follow the instructions on Page 37 of the manual about assigning a command to a footswitch. Select FS12 (the tap tempo switch) and pick a CC to send to the H9. The H9's tap tempo can be set to respond to whatever CC you want, so you can choose whatever you like. CC64 is what Line 6 uses, so it might be good practice to keep similar commands on the same CC.

I have the Mobius as well. I think with the Mobius' rotary, the Leslie cabinet itself doesn't seem to have such a large effect as it does with the Helix. If you use the Helix's rotary effects in place of the cabinet in your patch, it will sound a lot better, imo.

The TT comes with the DC-3g power supply. You can buy it directly from Line 6 from here: http://store.line6.com/accessories/power/dc-3g-power-supply.html Any 9V DC, center-negative power supply with the correct barrel size and sufficient current rating will work, too. I'm not sure what the actual current draw of the Amplifi is. I'd be surprised if it's actually that close to the 2.5A rating of the DC-3g, though. The Truetone (formerly Visual Sound) 1 Spot will fit, and probably work, but it's rating is only 1.7A, so officially not really supported.
