Settings guide for Tonex/NAM capturing with an HX Stomp

Tagging @Byrdman who might be interested in this info!


Here's a guide/preset for routing in Tonex Modeler for how I do capturing using an HX Stomps L Loop. The plus side with this setup is you can play your guitar and tweak the settings of your amp to better suit the DA/AD conversion that the Stomp introduces before you do the capturing and the normal outputs (1 and 2) are available for hooking up monitors to hear the results quickly.

Requirement: If capturing a full amp, a Line Out jack or a way to tap off a line out before a load is needed.

WARNING: ALWAYS MAKE SURE YOUR AMP HAS A LOAD ATTACHED TO A SPEAKER OUT, AND DO NOT CONNECT A SPEAKER OUTPUT FROM AN AMP INTO YOUR STOMP, EVER.

Also be wary of hum and ground loops when doing hi gain captures. The Stomp is susceptible to noise over USB, so test to unplug stuff from your computer if it's noisy. Also disable any noise gates on the amp or signal chain, since they might interfere with the capturing and aren't actually modeled.

My preset on the HX is simple with FX Loop L-block, a Volume block for if I want to mute the regular outputs and an IR block. You can download the preset here: https://www.dropbox.com/scl/fi/z5e2...ey=ohr7op62loz33tfpnptklbvja&st=n0zblg6t&dl=0

I put a +6 dB boost on the output to feed a stronger signal when doing captures. There are differing views on this so try it out yourself if you want it or not.
Make sure you have "Instrument" level selected in the global settings for Loop L on the Stomp as well.

And in Tonex Modeler the settings are like this:

Hardware-wise make sure to plug in what you are capturing into the Send and Return on the Stomps side, send into amp, return from the Line out or similar:

Continue the process in Tonex Modeler and you will be able to test out playing your guitar through the Stomps Send and Return.

Let me know if something can be made clearer and I can try to improve this small guide. It also works the same way for NAM capturing, just set up the same inputs/outputs in your DAW to send a sine sweep or dry guitar signal, and record Input 7 on a new track.

Cool.

What is the maximum dBu output level of the FX send (when set to line level and when set to instrument level) on the Stomp? And what is the maximum dBu input level on the FX return?

Mildly off-topic, but still relevant: How is the Stomp regarded as an audio interface, in general? And how about the FX loop?

(Edit: I bought a used HX Stomp not long ago, but haven't gotten around to use it much yet - and certainly not as the audio interface.)

I believe the max input is the same across all inputs, which is 11.5 dBu. I tried measuring the output with a multimeter but didn’t get understandable readings, so someone else can better answer that one.

I do think it is regarded as pretty good when it comes to quality of converters and such but it’s not great when it comes to latency. What I usually go for when recording guitar is to record both wet and dry, or dry only, and monitor via the device itself instead of via the DAW. That said the latency isn’t a big problem for me so I usually run plugins etc using the Stomp as well. But that is very personal.

Since I also use Helix Native the input gain is perfect from the beginning with a Stomp when recording dry.
 
If only interested in a DI capture, this is not needed right? Or am I confused again:rofl
Are you capturing both preamp and power amp? Then a line out/DI jack or similar is needed on the amp. As far as I’ve understood there are also utility boxes available with speaker cable passthrough to a speaker/load you can use to get a signal from the amp. And on reactive load boxes an output jack is of course available.

Otherwise you can of course do captures of just the preamp if you have an FX loop on the amp.

I’m just doing DI captures of my amp. What amps are you capturing?

Edit: on my amp I run the Line Output seen in the image into the Return of my Stomp. If you don’t have something similar you’ll need to add that functionality somehow.

I'm looking to DI capture my Marshall Origin 50H and SC20H. Both have line out so I should be good right? I will be hooking up my cab to the amp with an attenuator between the amp and cab.

STOMP SEND to the front input of the amp and Line Out from amp to STOMP RETURN

If you give me the green light, I'll be trying this later today.

Yeah man, the DI Out jacks should work as good as on mine! Just make sure to have a cab attached when doing the captures and let it rip!

The capture process went good with no issues. Some stuff was over my head like my Stomp XL said it did not recognize the IR in your preset, so I deleted it. Some of the levels were fine and other needed to go up but I could not figure out how, so I let it run the way it was. Maybe that will make a difference good or bad, lol...

It's training now for a little over an hour and says its at 31%. I hope it turns out alright. If this works good, I'll do my SC20H next. We will see what happens...
 
Okay everyone, I made my capture and it sounds pretty good to me, almost exactly like my amp when I did the comparison, but when I try to upload it to tonenet, I get this and cant figure out what they want me to do, lol...

Anyone know what's going on here?

Yeah IR’s aren’t present in the preset. You can switch to a cab block instead if you need it, but with the capturing process in Tonex now it’s not necessary.

Tomex is very finicky with levels, so if it sounds good when you dial in the levels before capturing, it’ll probably be fine. I have the send set to +6 dB in the preset as well which can make Tonex say that the send is too hot if I remember correctly, but in my experience works good anyways.

I say try a restart of the Tonex app and check the audio interface settings, then try again. I’ve never seen that one.

Success!! I still had the output as ASIO and when I changed it to Direct it uploaded just fine!

Here you go, my first capture:


If someone could try it and let me know what you think, I would appreciate it so I can do the next ones better.
