    Thank you Eric. While I am agnostic about modeling amps like Helix, your description of the SAG and how it changes the waveform was brilliant.

      Thanks man! To be entirely honest these days 99% if the time im plugged into the front of a tube preamp or a tube amp. for whatever reason the just feel better to me.

      @@ericharbauer I get that Eric. modeling amps are doing great jobs of trying to sound like a tube amp.
      I’m the same. I’m trying really hard to look like Hugh Jackman…😢

    Eric, Great video demonstrating SAG's effect on the visualization of a Sine wave! As you continue with your series of Helix Deep Amp Parameters, consider including an actual guitar tone (note and chord) to audibly demonstrate how changing the parameter's value actually alters the tone of the sound. In the case of SAG, the resulting clamping affect.

      Thanks! Good point, I will consider adding audio clips to the videos going forward.

    Happy to find your channel. Why are there not more of this kind of analysis style stuff, your the only guy that seems to be doing proper benchmarks of the so called 'amp replication' boxes.

    Thanks for starting this series for those of us "simple" guys who dont have years of experience with amps/pedals and lots of electronic/speaker tech understanding, but without the ability to see this sine wave on the Helix/processor, how do we determine how/where to set the sag adjustment on each of the amp sims on the Helix unit to get the best sound, since you are only going by sound not sight?

      Thanks for watching, I'm glad you enjoyed the video. As far as the settings go, my understanding is that the factory setting on the sag control most closely resembles the actual amp that was modeled, so it is a good starting point. From there, if you want more dynamics and touch sensitivity turn the sag up, and if you want a tighter response turn it down.

      Thanks for watching my video! I have plans to go through them all, I'm just not sure what order i'll do them yet. As I develop tests to demonstrate the effects of each control I'll be making the videos.

    Generally a compressor lowers gain with rising input, sag lowers headroom with rising input. Sort of? Comparison between power sag and cathode bias shift would be nice one too! Two different beasts, since cathode bias amps have much lower power sag, but distinctive compression.

    @V1BE127 3 года назад +1

    Would you think the Sag latency makes the sound artifactual?Cause it's pretty slower than the real amp sag isn't ?

    • @ericharbauer
      @ericharbauer  3 года назад

      I would have to say thats probably a stretch, there's so many things that go into an amp model. the slope of the sag curve is just one piece of it.

  • @samuelguymer4358
    @samuelguymer4358 5 лет назад

    If you have a kemper as well i would be highly interested to see a sine wave test and such of that and helix vs an amp to measure how accurate they actually are.

    @jimlund4845 6 лет назад +1

    Fantastic video Eric! That was really informative. I was curious to know what your experience has been with the sag "recovery time". Does the recovery time typically increase with the amount of sag or is it amp dependent?

    • @ericharbauer
      @ericharbauer  6 лет назад

      Thanks man, I'm so glad you lked it. As far as recovery time I have not looked at that at all. My understanding would be that as long as the amp is calling for power in excess of that the power supply can produce It wont recover, and once the demand lowers it should bounce back almost immediately, maybe limited by the amount of time it takes a capacitor to recharge. I'm guessing milliseconds here, but this is speculation on my part. I'll take a look at it and see if there's a way to measure that. Thanks again.

    @sumsebrumdadum 6 лет назад +1

    Really good explanation thank you! Would love to see the effect of the other deep parameters aswell.
    The master control in the models influences sag too, right? Its like the natural behaviour of the amp and if thats not enough you can use the sag control to alter it more?

    • @ericharbauer
      @ericharbauer  6 лет назад

      Thank You! I will be going through all the other deep editing controls over my next few videos. As far as your question about the master volume, the answer is yes the master has a major effect on the sag of the amp. The master dictates how much signal goes to the power tubes. The larger the signal, the harder the amp has to work, thus causing the drop in the voltage which manifests itself as sag. If the master is too low the amp may not sag at all. Thanks again for watching.

  • @boimesa8190
    @boimesa8190 4 года назад

    So would sag be desirable?? Would it make an amp sound more "natural"?

    • @ericharbauer
      @ericharbauer  4 года назад +1

      That kinda depends on the amp, and the feel you like as a player. For example a fender twin has a very "stiff" power supply with very little sag, wheres an tube rectified old marshall will sag much more. I generally like more sag rather than less sag unless I'm playing very clean, then ill dial the sag right down. but its very much a feel thing. you just have to try it and see what you like.
