Does your noise level change significantly when you plug/unplug the USB connection? Would you call that your main problem? Or is that a minor contributor to noise levels?

You also don't really wanna proclamate false things, You state false things to a newbie. I correct those so that the newbie doesn't believe false things. I replied to you, not the OP. If SNR was irrelevant, why did you confuse the guy with it in the first place? Otherwise you did a fine job replying to the OP - I didn't feel obligated to add anything of significance - until SNR was mentioned.

Not really. You get the best SNR right before the DACs start to distort. That depends on the patch levels and is not what you'd really want, because that signal is usually too hot for the input stage of the next device. What you usually want in front of an amp is a signal of the same level that the instrument plugged straight into the amp provides - which (given an empty patch with the impedance set to match the amp's) is done when Outputs = INST and VOLUME maxed / disengaged. This provides good SNR, good headroom and a neutral level.

Amps make guitar signals louder from instrument level to the level you get at an amp's speaker out. The cab and IR blocks tame the hot signal again to what a microphone including a mic preamp would pick up from a speaker which is line level.

This HX DSP allocations table is frequently cited when it comes to calculating DSP usage.

1. On modern high gain amps make sure the master volume is low enough to not compress/distort high frequencies. 2. Try a treble boost / eq (tilt or high shelf) in front of old school amps. 3. Try the "preamp + speaker impedance eq" way of doing things as discussed in this TGP-thread.

It does make perfect sense if you consider DSP usage.

No, there is no independent headphones sink. Global Settings -> Phones Monitor gives you two options: Main L/R or Send. This relates to the HX Stomp. Other units may vary.

So it was a ground hum then.

Experiment! There are no magic settings that work in all circumstances. Use the LOOPER as the first block and record a short guitar bit, Then fiddle around with the reverb parameters - especially with PREDELAY which can change how the guitar sounds due to phase interaction in the 0-40ms range.

Muddy usually refers to too much emphasis somewhere 100-450Hz frequency spectrum. A guitar can produce muddy sounds when it sounds dull. This can have multiple reasons: old strings, closed tone knob, a too distant pickup, very long cable, some kind of electrical defect. Check your dry unprocessed guitar sound and make sure it is balanced. If that is not the cause of your problem please tell us how you use the Helix / what you're listening through and what your goal of a sound is that you want to achieve. Ideally you'd also provide a patch that sounds muddy to you and even a recorded clip with a dry guitar and processed sound.

Do you have a mandolin and a violin each with electric pickup? Then you would record both the pickup signal and a mic'ed signal at the same time. Then you would use a match eq plugin to match the pickup with the mic signal as source. If that then sounds good, you can use a deconvolver plugin to bake the eq into an ir.

The HXStomp can fulfill all your preamp needs. If you use an empty preset, crank the VOLUME knob, set INs/OUTs -> Input Level to Inst and Output Level to Line your piezo input signal is amplified by a factor of about 100. The standard OUTPUT L/R is the right choice. A piezo preamp converts the pickup signal to a signal that works with instrument inputs by amplifying and providing the proper impedance.

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'.
