The last.

That means that the Helix is flat in the audible spectrum. So if your ears didn't trick you (did you check for equal volume?) and there is more top end in the bypassed Helix chain, it is because your original analog chain is rolling off some top end. To replicate that the high cut in the global eq is the prime candidate for this job. Second candidate is the high band: Set its Q value high and boost GAIN a alot. Then find the most annoying frequency by sweeping with FREQ. Then tame that frequency a little until you are satisfied. Only the length of the first cable to the Helix will damp some high frequencies which is fine. The second cable after the Helix transports a low impedance (buffered) signal, so that's fine, too.

I've just measured the frequency response of my HX Stomp with long term white noise spectrum analysis. The response is perfectly flat up to 16kHz.

Yes. Happened with v2.92 on mine.

All good. I think you measured the effect of the presence control. Sounds like a high shelf @2.5k with about 4dB boost.

The Buffer+ has a screw to adjust input loading aka input impedance. The Helix also is technically a buffer with adjustable input impedance. Higher input impedance results in less loss of top end frequencies. Helix has Global EQ, you can fine tune with that to match your analog rigs bypassed frequency response.

I can confirm that this happens occasionally.

Same here, if found the bass weirdly overpronounced when using Dirac impulses. As an electrical engineer I'm naturally skeptical of people's measuring methods. Please excuse! I found your file suspicious, but I've not come to a conclusion yet. I'll think about it, maybe it'll CLICK.

Did you compare that IR with a solid state version using that same method? How did you do it? Click or sweep?

A power amp's sound very much dependents on the impedance of a cab. Measuring it without a load is useless.

While this is true, modern amps that are more preamp based tend to be have a more neutral poweramp. A 6505 poweramp (like Friedmans, Revvs etc.) is much more neutral compared to a vintage style amp like a Twin (depending on the Depth and Presence controls of course - I'd guess they should be at noon for the most neutral sound).

That's what I do if I don't use (mono) post EQ.

Pretty much my experience, too. I forced myself to play around with the cab block and started to like it. Now I'm really happy with what can be achieved, especially in the dual cab mode. The two things on my wish list: - a mono switch or pan knobs in the dual cab block - support of dual cabs in the amp/cab block

Those observations are correct when input and output level are set to Inst. Which should be what you want in your use case: Just turn up the volume knob of your Helix all the way and you're done. Helix is now set up for unity gain - one thing less to worry about. Here is where the Input Impedance setting of your patch comes into play. It should be set to Auto to recreate the feel if you back of volume / tone on your guitar - especially with fuzzes. Or which volume know are you talking about?

Generally agreed, but some use IRs to simulate the body of an acoustic guitar. Those IRs are as short as those of cabinets. Also capturing dialed in EQ of your favourite console channel strip, the JHS Color Box etc comes to mind.

IRs in the Helix are max 2048 samples of anything. Which means the sample can be max 2048/48000kHz = 43ms long.

And In particular this video is worth watching, comparing apples to apples (real amp signal vs Helix).

Also things to keep in mind regarding your guitar: - string age (old wound strings sound muffled compared to the others) - pickup height - it has a tone knob - it has a volume knob - cable length With a real amp I use tone and volume on 7 on my guitars when I dial in tones. Same with Helix.

If you think it sounds bad, try to record your amp with a mic and evaluate whether that sounds good to you. If a Helix amp sounds muddy, it's because the real amps sound muddy when dialed in like that. If sth. sounds good in a mix it usually sounds mediocre isolated. If sth. sounds muddy and harsh at the same time, can you guess what's missing? (Hint: A tube screamer might be the cure for overdriven and a klon for clean tones)

Mono switch for dual cab block.

Xsonic Airstep i.e. does MIDI switching via cable and Bluetooth.

ANGL Meteor. Its hard rock / metal sounds are probably the closest - and AWESOME.

Yes, this possibility exists.

Read the whole thread! It's Alex Price.

My favourites are Room, Plate and Spring 63. I tend to use 30ms Predelay, open up the HighCut and reduce the mix. Room for subtle, Plate for obvious and Spring for vintage reverb. The spring sounds great before the cab or amp.
