Authenticity - a lot of those amps don't have master volume in real life. If you would solder one in and crank it it wouldn't do anything to the signal - it's a variable resistor set to zero Ohm resistance.

Select a cab/IR block in a patch and put it on path B. Now select the mixer ( the symbol appears when you move to the junction of the two paths) and put it on path B, too. Done!

Maybe you have a 1A 9V Boss power supply? You need a power supply with 9V, at least 1A and a reversed polarity 5.5mm diameter plug.

I don't see why not. Split the stereo cable, put the pickup side in the Input L and the mic signal in the Return L. Set Global Settings -> Ins/Outs -> Send/Return to Line. This sets the Return input impedance to 10kOhm which is ok for dynamic microphones. Set the patches Input Main L/R -> In-Z to 1MOhm for best impedance for the pickup. Then use a ReturnL block to mix in and level the mic signal.

After amp, before cab. As you've hopefully seen I've linked the patch and clip. You can inspect a patch directly here.

Here are the settings of a patch and clip on SoundCloud I did some time ago for another request by ear. Dual Pitch Stereo Interval 1: +0 Cents 1: +10.4 Delay 1: 13 ms V1 Level: 10.0 Interval 2: +0 Cents 2: -11.2 Delay 2: 13 ms V2 Level: 10.0 Mix: 38 % Level: +3.0 dB V1 Pan: Left 75 V2 Pan: Right 75 Dry Pan: Center There obviously will be a difference when used mono.

Congrats on finding a thing that makes you enjoy playing guitar. I'll check out some day, too. What Mesa cab is it, a Thiele Cab?

Do you still own the Marshall - Suhr - speaker sim system? You could A/B both directly by putting the Marshall and Suhr in the Helix loop.Use a Looper block - play a riff - and then A/B both systems. I'd start with the Revv Gen Purple amp block with Aggro at 1 to match the DSL.

The obvious and only right answer to that question is: define plastic!

Define 'digital tinge'. Here is an A / B comparison between Helix and it's high end analog tube amp counterpart (well 100w model vs. 50w version). Please tell me what to listen to in order to observe that 'digital tinge'.

Yes, multiple solutions are possible. Could you be a bit more specific: When you play rhythm do you want to hear the signal through L/R or Send?

Maybe start with listening to some pedal nerds? I've looked up 2 of a gazillion videos that somewhat answer your questions:

Use it with Global Settings -> Ins/Outs -> Send/Return set to Line. That switches the Return input impedance to 10kOhm. A dynamic mic has an output impedance of about 0.3kOhm while a standard pickup has 6 to 12kOhm. A good damping factor (rule of thumb) is 10 to 100. Dynamic mic: 10kOhm / 0.3kOhm = 33 Electric guitar: 1MOhm / 10kOhm = 100 I get some weird 'touching noise' when I use a mic with 1MOhm and touch the HX.

I was just connecting the dots: there have been generations of guitar players who made the same experience you did, just with different technology. You are in the lucky position of being offered the whole palette of tones at your fingertips.

Use 136kOhm to emulate plugging into input 2 (or low input) of a Fender style input stage.

A simple XLR Female to straight mono jack 6.3 mm will do. Put it in input L or R, lower the IN-Z to 10K-Ohm in the Input Main L/R block and use a Studio Tube Pre preamp block with pretty high Gain and Level.

Since you use the HX Stomp: Try a parametric eq block in the end of the signal chain to find the frequencies you're not liking and adjust. This resource on equalization might help - especially 'Approach 1 – Remove Nasty Elements'.

Don't expect answers to questions you have not asked... Be specific, be precise, be concise - that increases your chances for good answers.

Yes, you can do that. Just rename "left channel" to "mic-channel" and "right channel" to "acoustic channel" in your head. You can apply FX blocks to just one or both channels or any mix in between. There are ultimately two ways of usage of the Felix output DIs and you'll have to chose one: Guitar and mic (double mono) OR left and right (stereo). That decision affects the way you use the HX, but both ways are possible.

From the Felix2 website: Use the dual mono fx mode, connect the Felix fx send to HX input L and R with a stereo to L/R TRS cable. In the HX split L/R and use one path for guitar FX and one for vocal. Connect HX Out L and R with Felix's fx return via (another) L/R to stereo TRS cable.

Well, the difference between headphones and main outs it the output impedance. Hx's headphone outs have about 10 Ohm to be able to drive current / move headphone speakers. The main outs have about 300 Ohms and are designed to maximize signal transmission quality for standard audio input stages. They work best with 10kOhm-ish inputs. You described a connection with a high damping factor (Df = Z_load / Z_souce = audio input /headphones out =10k / 10 = 1000) results in a slight enhancement of high frequencies. It gets more audible when plugged into amp (Df = Z_load / Z_souce = guitar input /headphones out =1M / 10 = 100.000). Look up impedance bridging for a technical explanation.

Parameters that influence input gain: Global Settings -> Ins/Outs -> Input Level Input block -> In-Z Global Settings -> Preferences -> Auto In-Z if Input block -> In-Z is set to Auto

No, the opposite: a low impedance of the Helix is driving a high impedance input of the amp.

According to ADAM audio these speakers deliver a max SPL >110dB @1m per pair - that's fairly loud. My ADAM A5x pair is pretty loud, too.

The Helix is able to deliver about +19dBu in line level mode before distorting the DA converters. If you have a preset that puts out -15dBFS and you crank the volume knob you get +16dBu at the output. I'd guesstimate that the patch is +10dBu with the volume knob at 2 o'clock which is twice the level of +4dBu and might well be the max headroom of the Adams input stage.
