Using Drz 2x10 cab with Drz amp profiles?

  • Does anybody know if a DrZ 2x10 cab would give pretty faithful results if used with profiles of DrZ amps (with the cab turned off, obviously)? I am thinking particularly of the official profiles produced by DrZ himself but I understand that there are other good profiles available out there.


    I use my powered toaster almost exclusively for live use and have yet to find a cab that I am particularly happy with. Having owned a couple, I really dig DrZ’s amps and, as I don’t have unlimited resources to explore and experiment with umpteen different cab/speaker combinations I thought this might be a particularly good solution?


    One question that has occurred to me is how does the Kemper produce the base-tone (by that I mean the tone that a particular amp produces before it is shaped/coloured by particular cab/speaker/mic combinations) of any given amp? Obviously, when “cab” is turned OFF, the Kemper removes/defeats/bypasses the cab/speaker/mic contribution to the tone but how does it know how to do that? As I understand it, profiling is always done by the Kemper “listening” to an amp at the speaker, or am I mistaken and can amps be profiled just at amp level without factoring in cab/speaker/mic influence?


    Gosh, that was longer than I intended! :|


    Thoughts and testimonies much appreciated!


    Cheers

  • You are right about removing the cab/mic with monitor off...its an algorithm so will be an approximation...


    So your options are I think:

    1) Go as you suggest - it won;t sound exactly the same but should bbe ( I emphasis should) be close

    2) Go FRFR - you stand a better chance of getting closer plus its more flexible should you go off DrZ stuff

    3) Get a direct or merged profile which is don't without the cab so is more accurate of the amp itself.


    Hope that helps..

  • When I try and add a cabinet (from those I have within the Kemper) to a direct amp profile, it doesn't sound great.


    When I play a direct amp profile through an actual cabinet, it sounds so much better than a merged profile with the virtual cabinet turned off, running through a cabinet.


    Dunno why...but it does :)

  • This is from the Kemper manual (pg 52). Basically, the Kemper guesses where the line between amp and cab should be. It works surprisingly well IMO :) Direct profiles will give you just the amp (preamp/tone stack/power amp) without the cab. Merged profiles are specially made with a 2-step process to achieve perfect separation of amp from cab - basically a Studio and a Direct profile in one.

    Separating Amps and Cabinets: CabDriver

    Regular Studio Profiles are created using a guitar amp and a guitar cabinet, captured by a microphone (or several microphones). The resulting Studio Profile is split into two portions: Amplifier and Cabinet Profile, with the sound of the microphone becoming an integral part of the Cabinet Profile. Since the Studio Profile is taken in one go, it is complete and perfect as it is. While there is no exact information about the separate sound of the amp or cabinet, the Profiler uses an intelligent algorithm to create the best approximation of a separation line between the Amplifier and Cabinet Profiles. This algorithm is called CabDriver. CabDriver makes it possible to separate the Amplifier and Cabinet Profiles of a Studio Profile and combine them with those chosen from another Rig or Preset. It also allows you to switch off the guitar cabinet simulation (“Monitor Cab Off”) to drive a real physical guitar cabinet. The typical interactions between the original tube power amp and the cabinet are captured within the Amplifier Profile. The result is thus highly authentic, and ready to be amplified by a solid-state amp, or the optional, built-in class D power amp of the models PowerHead and PowerRack.

    ?Fully authentic results can be achieved by taking or using so-called Direct Amp Profiles.
