    $\begingroup$ Badly distorted how? Can you edit your post with a graph of the impulse response? Did you try doing the procedure with an identity impulse response, i.e. a 1 followed by a bunch of zeros? Did you try it with an impulse response with gain, or some simple filters (a low-pass filter would be good -- maybe 1 millisecond worth of ones, followed by zeros)? $\endgroup$ Commented Nov 12, 2019 at 20:28

    $\begingroup$ i think you're conflating guitar simulator (these are hex-pickup pedals that Line6 and others have made that make your guitar sound like a variety of different acoustic guitars) with guitar amp distortion which is much more complicated than just an impulse response. $\endgroup$ Commented Nov 12, 2019 at 21:06
  • $\begingroup$ i wonder if someone has a got link to a general description of Volterra series? $\endgroup$ Commented Nov 12, 2019 at 23:53

    $\begingroup$ @robertbristow-johnson if "diagonal Volterra series" a.k.a. "Hammerstein model" is enough for you, have a look at Angelo Farina, Alberto Bellini and Enrico Armelloni "Non-Linear Convolution: A New Approach For The Auralization Of Distorting Systems", Proceedings of the 110th AES Convention, 2001 and the presentation of the same name. $\endgroup$ Commented Nov 13, 2019 at 8:05

    $\begingroup$ Olli Niemitalo, thank you for the links, there is indeed some useful info there. $\endgroup$ Commented Nov 13, 2019 at 14:28
