K. I think you woke up in 2024 on a different planet. But hey, whatever.
- Can't deal with phantom power.
- Worst visibility in its class (one of the reasons for me to sell it).
- Risk of blowing the mic preamp when switching phantom power on/off while mic is connected.
- Switches are just bad and plenty of people had to have them serviced (at a time, out of 6 Helix owners I know in pereon, all but one had to have the Helix sent in for some service).
- Joystick is a (nonsensical, btw) wobbly affair, breaking almost as often as the switches (at least in case you're using it often).
- At least on the HX Stomp, the "noses" of the USB socket seem to come off rather often.
And no, I'm not making any of these up. You will read tons of stories about just how great the Line 6 customer support is (which, fwiw, is only true in North America, in Europe it's downright horrible, a guy I know had to wait over two months and didn't get an overnight replacement, which is what some US folks are often talking about). And while their US customer support might be great, why do you even have to deal with it? Correct, because the units are breaking often.
