See the manual p. 38: Setting Path B’s Output There may be situations where you want parallel Path B to be sent to a completely different set of outputs. 1. In the Signal Flow view, turn the Big Knob to select the point where the two paths merge. The Mixer block appears only when selected: 2. Touch Footswitch 2 and turn Knob 2 (Path B Output) to select “Send12.” The Mixer block splits into two, indicating Path A is being sent from the HX Effects hardware’s Main L/R outputs and Path B is being sent from its Send 1/2 outputs.

Yes. Use the View button to get to Play view if it's not active. Press the upper knob to navigate to the preset list. Press the middle "Snapshot" knob.

I read this as you use the Stomp as USB interface and the monitors are directly connected to the Outs. Is this correct?

Make sure Global Settings -> Ins/Outs -> 1/4" Outputs is set to Line if the problem is low output level.

To much level causes clipping. I guess you use the delays and the H90 after the an amp block?! Lower the amp block's Ch Vol parameter to increase the headroom for the blocks that come after it.

No. Did he ever share that preset? Anyways here is the video for reference: Bonus clip from his own YT channel:

From what I understand the Helix algorithms run at 48 kHz on the DSPs and while the USB interface offers other sample rates these are converted from / to 48 kHz. 96 kHz isn't making stuff faster or better - it's twice the amout of samples without a benefit is what I was trying to say. I might be wrong about this.

The method in the video is also valid and it saves you one block, because the Send block isn't needed. Different cabling though.

Helix is 48kHz. With 96kHz you basically record every sample twice via USB.

In your 4CM patch add an IR block last in the Path and a Send 2 block before that. Connect: guitar -> HX In HX Send 1 -> amp input HX Send 2 -> amp return HX Out -> FOH amp Send -> HX return 1

Reading the manual is a very good idea. It was written for you to get the most out of your Helix. Here is a video that shows how you can build an A/B foot switch:

Use a preamp and an fx loop block in series in your patch. Engage Stomp Mode. Bypass assign both blocks to the same foot switch. Bypass one of the blocks manually so that one is bypassed while the other isn't. Done.

Here are some settings from another forum for you to try: 1: Gain -6.2, Q 10, 257 Hz 2: Gain 9.0, Q 10, 926 Hz 3: Gain 7.8, Q 0.7, 4.3 kHz This looks like it takes out some U vowel sound (250 Hz), add some A vowel (1000 Hz) and a lot of E (4 kHz). Btw: if you find Q values for non-Helix equalizers you need to square them to apply them to Helix.

To answer your specific question: If you manage to mute the not-in-use guitar itself (turn down the guitars volume knob) a +6dB mono Gain block is enough. You can replace the Gain block by any other mono block if the 6dB level loss when using both L and R inputs doesn't bother you. To mute one input put a Pan block first in the chain and set it 100% left or right depending on the input you want to use. BUT: If you don't use the fx loop here is an alternative that doesn't need extra blocks: plug the acoustic in the Return L and the electric in In L. Switch between the inputs by selecting the input block and turning the lower knob. And if you need one fx loop: you can plug the acoustic in Return R and use a Return R block first in the chain in your acoustic patches, the FX Loop L block would be for the fx loop.

Also: Filter -> Legacy -> Q Filter with expression pedal controlling Freq.

Press the parameter knob and while pushing turn. Or long press the parameter knob, then change Controller to Snapshot. To undo: long press the parameter knob, press the Action button, then Clear Controller.

I use Tangzu Wan'er in-ears. Very affordable, well balanced and never get harsh. They don't fatigue the ears, have good detail and I enjoy playing through them. You might need a TRS extension cable if you use the Floor on the ... well ... floor.

In Snapshot Mode use an Instant Command to set Ext Amp to 1, 2, 1+2 or None. The settings are per snapshot. Since you've skipped several firmware versions: it might be a good idea to read the new manual otherwise you might miss out on some new features. Have fun!

You could load the IR in a sound file editor or DAW, see if it's normalized and - if not - normalize it. Audacity is free and can do that.

I'm a big Deep Purple fan. Their guitarist Simon McBride has a stereo setup that might be inspiring for you: Listen to this with headphones to experience when / how much he uses stereo.

The expression pedal works optically: the angle of the pedal is determined by the amount of reflected light. To achieve that an LED emits light that gets reflected by a white surface (at the end of the metal bar on the pedal) and is picked up by a photo detector. Something in that mechanism doesn't work. Do you see that "sensor light" when Helix is on? Is the surface white, above the sensor and reflecting the light? Don't touch anything in side the Helix when it's on unless you know what you're doing.

Presence is a low-pass filter for the NF, Depth/Resonance usually a variable high-shelf. Just looked up the schematic: the og 5150 III has a fixed 150Hz high-shelf in the NF on channel 2 and 3. To be clear this means that frequencies below 150Hz are boosted in the power amp. Or in other words: the speaker cab's low resonance (110ish Hz) is less tamed than the upper frequencies. There was a patent on the Resonance control by Peavey so Fender/EVH wasn't allowed to put it in the og 5150 III. Bogner used a switch instead of a pot and called it Depth (e.g. the Ecstacy) to get around that patent btw.

Also keep in mind that my file was just a one bar / start of a song example. You can automate whole songs with a MIDI track. Also you probably want to alter the order of the three MIDI commands in my file before you make it a template: CC#32 0..7 to select the setlist PC 0..127 to select the preset CC#69 0..7 to select the snapshot Be aware of the MIDI value vs. number offset: e.g. CC#32:7 recalls setlist 8 (7 + 1 offset) which is "Templates".

You could use the Global EQ to tweak the mids. I use Tangzu Wan'ers - super cheap and good enough for me.
