More tone stacks Liquid Profile anytime soon?

  • Many of the high gain amp schematics and boutique amp schematics are not to find or not easy to find. I don’t believe that there will come so much more to the Kemper list. I don’t believe that Bogner Diezel Mesa, etc. would be amused to see more perfect profiles.

    But, yes some of the classic amps like Dr103 could follow.

    I actually had the the full Mesa service manual in PDF form with all the schematics in it but I can’t find it now unfortunately.

  • I’m not sure I understand what you’re saying by that.

    Oops! I was actually intending to respond to someone else that quoted you, I think it was Aehaem. A case of bad editing. Anyway what I am saying is yes they could make a list of similar tonestacks and it would not be difficult to even do those but I'm more interested in the ones that are not similar because yeah I can use the JCM 800 for my JVM 410 but there's nothing to use for a hiwatt than the generic, and that isn't close at all..

  • Or maybe really just a description of how every "EQ amp type" is working. I suppose many many people never had direct experience with most of those amplifiers.

    To get some knowledge about how they are working would help us to select them based on what we want to achieve and to use them efficiently, instead of only looking for the original of the profiled amp.

    The Duncan Tone Stack Calculator on the web can do that really well already. Find a schematic of the Amp and insert the component values in the Calculator shows real time graph of the effect of moving the tone controls. For example it is incredible just how “scooped” the Fender blackface amps really are with all controls at 5.

    Correct, and I love that tool. But I assume that a lot of people would have no idea hot to find the tone stack portion of the amp schematic circuit, find the resistor and capacitor values and interpret the output graph.

    And even with the Duncan calculator is difficult to remember the complete behaviour of the tone stack.

    I think is a lot more beneficial a short description of the various stack behaviour as part of the manual. I never found them documented anywhere.

    I totally agree that an explanation in the manual would be great but I’m not sure how they would go about it. So much of the description might need to be totally subjective which could limit the usefulness.

  • I think Kemper would do a favour to many (most?) by creating a list of real amps that share TS structure: this would multiply "for free" the perceived versatility of those already available.

    One thing that's not clear to me tho is whether the above-mentioned models actually recreate the interaction among the real tone knobs, besides offering the same curve centres, Q and gain: we know that in real life each knob equalises the incoming tone differently depending on the other(s)' position, which is the core of a given TS.
