Matching Bogren one knob amps with Helix

[pipelineaudio]

Thanks to @James Freeman , I am able to much easier match tones, especially the really difficult, non linear parts. However I've been busting my balls to try and match either vitriol or panama to Bogren 66o6. With -6dbfs pink noise, and using an impulse match and capture, I can get them to nearly null, but when I actually play the guitar (no matter what reference level) the entire frequency spectrum tilts with the match tone slanting from below the original on the low end to above the original on the high end...Any clue what this could be?

How do I know where to set the master volume on Helix? What about the Bias?

 

[James Freeman]

Give the pink noise a lowpass at 1kHz 12dB/Oct, particularly with the high input level, it will be more similar to a guitar frequency response.
At the linear region (low input signal) you can use flat pink noise or leave the lowpass enabled.

I'm really wondering how in the world to properly set the gain and other things like master, bias and stuff.

I used your -75 to try and match distortion levels and -15 to set the overall volume and then back and forth till they were similar.

The crazy part is just how perfectly the IR capture method got the noise to where they pretty much nulled. Hopefully your 1k filter trick will help

I say this with love.


But why keep wasting time trying to pound a square peg into a round hole? Use something else that does the sound you want it to do.

Why is learning how to use gear a waste of time? I love my Helix, and I want to use it to the best of my ability and beyond

Learning and succeeding is not a waste of time at all. Trying to make the Helix sound like 576 different high gain plug-ins instead of just sounding like the Helix is a waste of time

I got a hunch that Line 6 reading this and be like:

I was under the mistaken impression that the helix's high gain amps were meant to sound like high gain amps

Using gear to emulate gear that emulates gear.

But to be honest, it‘s just so much fun to do such things, isn‘t it?!

 

[pipelineaudio]

Theyre all meant to come to the same end, I don't care what's in the black box

And really, I'd LOVE to know why things aren't acting as I'd expect they would. Its very much like I'm seeing 2+2 and getting 5 and not sure why

Tone matching is fun. I like to get close with the amp + ir, then use a looper, load up a parametric EQ and some filters and go to town using SPAN.

@James Freeman I'm using your -15 and -6 pink noise files, are they already filtered at 1khz?

Here is an example of when I use a guitar riff to do the impulse match. It matches the riff perfectly, but if I run noise thru, I get the top picture

On the other hand, if I use pink noise to make the impulse match, it matches the original perfectly when i play noise thru it, but if I play a riff thru it, I get the opposite of the picture above

One capture method tilts the eq towards the highs and the other tilts the eq towards the lows...I'm assuming this is from one of the nonlinear components maybe...What can I do to get both to match better?

Filtering the noise really helped! I'm still a bit off with the exact distortion, but I can no longer ABX between them
