  1. snhirsch, totally agree.

    1. Electronics was disconnected, piezo directly into the POD (3.5 Mohm). POD was used only as USB sound card. No audio processing.

    2. The reference signal was of course connected to the input for piezo (piezo unconnected). But I wrote previously, this measurement is not objective.

     

    psarkissian,

    "I have found the 3.5 Meg-Ohm input impedance to be one of the settings with a higher noise floor" - totally irrelevant

    "...as for the DSP, he would  need a schematic or a chip data sheet. And

    even then there would be too many..." - You should know that it is nonsense to connect or measure anything after AD converter. I do not need schema for connecting the signal to analog input.

     

    The important thing is this: at the string E6 is heard "clank tone" G # - 1660Hz. The measured value corresponds exactly to this. The origin of this sound is thus clarified.


  2. snhirsch,

    I used POD HD500 - input impedance 3.5 Mohm. I see no problem in this. More problematic is the measurement of the frequency characteristics of electronics. Frequency response is changing (I assume) depending on played tone. This can not work when using noise. However, the measurement result corresponds to how the defect manifested.

    "On a more general note, I don't see why Line 6 slavishly model every aspect of a guitar including its faults."

    It is not modeled. This is a fault of JTV.

    In the video I try to prove that the longitudinal wave is an integral part of sound at every guitars (anyone can verify). Magnetic pickups do not have the problem usually - on my JTV the L-Wave is very loud on the string A5 and therefore magnetic pickup captures this.

     

    If someone says:

    "that particular Strat is supposed to have that kind of Low-E sound."

    So it is a mistake or a deliberate lie.


  3. As for the the Model itself is from a vintage 59 Strat. I've had this talk with the programmer. Yes, it's going to have a bit more something about it that unfortunately Miroslav doesn't like. Popular with blues players, but not with metal players (seems to be the pattern). So yes, that particular Strat is supposed to have that kind of Low-E sound. Apparently it doesn't mix well with how Miroslav is using it.

     


  4. " And the guy from L.R.Baggs explained a number of things about the aspects about piezos" - "What I can say, is that the "clank tone" as it is commonly defined, is, in fact, part of every Piezo bridge pickup."

     

    "Now, it's a matter of narrowing down the source." - Ask the guy from L.R.Baggs.

    Strat is supposed to have that kind of Low-E sound. ?

    Telecaster is supposed to have that kind of Low-E sound. ??

    Gibsons are supposed to have that kind of Low-E sound. ??? 

    Rickenbacker is supposed to have that kind of Low-E sound. ????

    Gretsch also?

    I'm not a metal player.

     

    "A number of causes have already been eliminated from the list of causes. Any other ideas?" - "What is clang-tone? Clang-tone, or wolf tone, is a sound inherent in a vibrating string. A string vibrates in three modes: Torsional, Longitudinal, and Transverse. Torsional vibration does not produce a sound wave – it is the string just twisting like a drive shaft in a car. Longitudinal vibration is what the magnetic pickups on a guitar are “hearing†and reproducing. Transverse vibration is a wave going up and down the string as it is stretches and relaxes longitudinally. Magnetic pickups do not reproduce Transverse vibration, but it is the type of vibration that a piezo pickup “hears,†and it produces the clang. Some describe its sound as a “ping†or “plink.†It is there even on acoustic guitars....

    ...They did a great job. Between Lloyd and Michel’s work on the clang-tone issue, and some slick DSP algorithms by our engineering and sound design guys, clang-tone has been essentially eliminated

    On the string A5 - Yes. E6 on the string - not.


  5. A little boring here. We have 400 posts, it wants a celebration.

    Line6 director should utter a solemn speech.

    Maybe something like this:

     

    "Dear customers,

    in this solemn moment, thank you for purchasing of our products and for your patience. We have reason to celebrate. 400 posts!

    So many, many words have been written without anything been said. It is not a shame. This is a success - our great success!

    I thank you also to all our employees who worked tirelessly and again and again they said - nothing.

    Thanks again to all and for the future I wish nerves of steel. "


  6. With musical instruments, any L-waves would be more in keeping with hollow body. I'll need to look deeper into any research with solid body intruments.  

     
    We do not deal L-waves in the wood or in the air. Thankfully. We have "simpler" problem. L-waves on the string - steel.
    But here my sense is in the end. I have not found a link between: frequency (1,6-1,7kHz), speed of sound in steel (5000-6000 m/sec) and length of the string (0,63 m). Maybe it complicates the cores/wrap wire of string and also mechanical properties of the bridge.
     
    "Untrusted ..."
    Do not be angry, I still feel that your task is not solve this problem, but only production of fog.
