  1. I do not want to offend you, but I solve this problem with you and your colleagues since Sep 29, 2013. Even before the guitar was twice in a repair shop - piezo / bridge.  I'm angry.

    I do not know the details of modeling, but I imagine the problem like this:

    The A5 string on most guitars (including the JTV) creates a significant longitudinal waves. You are creating an algorithm that adjusts the input signal (including the longitudinal waves) into shape of A5 strings on the Stratocaster (for example). OK.


    E6 string on most guitars have not so significant problem with the longitudinal waves. You are creating an algorithm that adjusts the input signal (without the longitudinal waves) into shape of E6 string on the Stratocaster. OK.


    However, there are a smaller number of guitars, which have on the string E6 the longitudinal waves a greater,  or these waves have a different frequency - compared to a reference guitar.


    Your solution? - This problem does not exist.

    my strings is D'Addario EXL110.

    I auditioned also GHS 10-46, it was the same.

    The action height of string E6 at fret-12 is 2mm.

    One information that worthy of consideration:

    The bridge was replaced by from other guitar in the shop. Maybe the same production series of the bridge.
    "The "clang tone" post would be useful if all the piezos had that problem."  No. It is an accurate description of the problem.
    I think you'd better contact "your engineering and sound design guys and also Lloyd and Michel."

    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.

    Numerous times Lloyd and his crew met with a Line 6 team that included Line 6 co-founder and chief technology officer, Michel Doidic. We showed Lloyd and his people what we were up against and they took the bull by the horns to help us tackle it. 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. (Big kudos to Lloyd and Michel for spearheading this.)

  4. Everyone is using the same firmware. Everyone has a different physical guitar. 


    This is precisely the whole problem
    A different physical guitar -  a different intensity, maybe a little different frequencies of the longitudinal wave.
    And the same firmware. This can not function.
    " haven't solved the problem, but only masked it."
    Yes! The A5 input masked the problem of string A5. If is E6 piezo connected to A5 input, then is masked a problem of E6. But E6 input does not masked it. It is fault.
