No. Older Helix's had problems with noise introduced by phantom power though. How does a guitar sound like that's "not enabled"?

In Europe a Stomp comes with the Line 6 NSA27EU-090300 - a switching power supply without transformer or ferrite bead. There are loads of compatible power supplies on the market if you're not satisfied with the original.

To me this reads like a hardware defect. There have been rare reports of errors / defects that start to occur after some time of "heating up". Like: https://line6.com/support/topic/58488-sound-stops-after-anhour-every-time/ You could go into hardware test mode -> UI Test. Press FS4+5 on startup for this. In UI test don't touch anything and wait for some minutes to see if any switch is triggered on it's own. And you could stop the time until the defect happens after startup of the cold unit and see if that time span is somewhat consistent. But: I doubt that this leads to any clue that you can use to fix this yourself - unless you're an electronics guy. The offical service centers can repair it.

The difference is in the wiring. Without soldering iron you can cut the green cable(s) inside and use a dual mono to stereo 1/4" cable. With a soldering iron you can mod the SP1 to become a L6H in two minutes: Desolder the cables coming from the switch from the output jack 2. Output jack 2 is not needed. Desolder the green cable coming from the pot from the output jack 1 and solder the red cable from the switch there instead. Solder the black cable coming from the switch alongside the black cable. The output jack now looks like this: the two black cables (from the pot and the switch) on the sleeve the red pot cable on the tip the red switch cable on the ring

If you want some hands on experience with Q you can call (323) 634-5667. (See Star Trek: Picard, S02E05 "Fly Me to the Moon") Or try the Filter->Legacy->Q Filter and assign an expression pedal to the Freq parameter.

Yes. Path A and path B are stereo. If you use a hard panned Split Y you split a L/R signal to L/L on path A and R/R on path B. If you mix L/L with R/R (default Mixer setting) you get L+R/L+R, but if you hard pan the Mixer you get L/R.

With default settings Split Y is the same as Split A/B. With a Split Y block when setting its BalnceA to L100 and its BalnceB to R100, you can process the L and R channels independently. With a Split A/B block both path A and B get the same stereo signal with levels chosen with RoutTo. So with your setup use the Split block as Split Y with the hard panned settings mentioned above. This way you give each amp one side of the chorus signal. Make sure to also set A Pan to L100 and B Pan to R100 in the Mixer Block to keep both amps separated in the stereo image.

I wouldn't recommend these either. They work ok, but: What you want is an expression pedal with a linear 10k pot. If it has a logarithmic pot the pedal doesn't work evenly. If it's lower than 10k you don't reach 100%. And if it's bigger than 10k you reach 100% too early. In other words: the expression input reads the resistance - each 100 Ohm step translates 1% step in the HX. I.e. 2500Ohm/100Ohm = 25%. Anything above 10kOhm (10000 Ohm) translates to 100%. It really is as simple as that.

The MVP is an active volume pedal. No chance to use it as expression pedal.

The Presonus' have eq on the back - check if it's set neutral. The Helix has a global eq - make sure it's off. Try lowering high cut in the cab block. Try less presence and/or treble in the amp block.

I hope they implement this in the future: 64...127 emulates FS press 0...63 emulates FS release

cabling: guitar -> LT in left LT send 1 -> PT15 front PT send -> LT return 1 LT send 2 -> H90 in H90 out -> LT return 2 LT out left -> PT return Use fx loop 1 if you want the PT15 preamp. Don't use fx loop 1 if you use the vox amp model. Use fx loop 2 for H90.

Yes, in terms of duration the following applies: dotted 8th = 1.5 x 8th = 3 x 16th dotted 4th = 1.5 x 4th = 3 x 8th = 6 x 16th "Dotted" and "triplet" cancel each other out, i.e. a dotted 8th triplet is an 8th note.

If this works then connecting Exp1 with CV/Expression out with a TS patch cable should work, too.

Select the wah block, press Action and disengage Snapshot Bypass. (That's at least how it works on the HX Stomp)

Depends on the electromagnetic fields in the room. Compare the in between pickup positions with the single coils (2,4 vs 1,3,5) - then you know (unless you have rather rare non-reverse-wound middle pickup). In my room my PC introduces some hiss and I need to turn a specific angle or move away to minimize it on single coils.

1. If the noise gate doesn't entirely get rid of the hiss part of the hiss is probably added after the HX. 2. Guitar pickups tend to pick up noise from the environment - single coils much more so than humbuckers. With Strats or Teles try the noise canceling pickup positions. Also try moving the guitar and find a spot with minimal noise and hiss. 3. Try the Dynamics -> Horizon Gate with Sens at 1 in Extnd mode (as starting point) in front of the amp. It's a dynamic low pass and tames high frequencies (hiss) instead of the whole signal. 4. Your amp setting has a maxed presence setting on a (bright cap treble boosted) Twin Vibrato channel. In other words - very accentuated high frequencies (and therefore accentuated hiss). A high cut after the amp will mitigate that.

Make sure all connected Bluetooth audio devices are paused. Ideally you use both the L out and the R out with a dual mono 6.3mm to stereo 3.5mm cable.

Just to avoid you asking the follow-up question in the future: yes, batteries can run empty at times and then need to be replaced.

To me this looks like Line6 have a bug in the manual and in the firmware. Still waiting for confirmation or refutation by other XL users regarding MIDI CC#56.

See XL manual.

It can only be something before the Blues Driver that is causing this. Vox's battery empty? Vox defective? cable defective?

Why not use both wah and volume with EXP 1 only and toggle both bypass states with FS5 (FS5 Function to Stomp5 instead of TogglEXP)? Seems the more straight forward solution to me at least.
