    Hi All.

    New AFB user here. So far i am quite impressed with the tones i am getting out of the AFB. I have placed it at the front of my small/ fly rig pedal board to give me as much flexibility as possible in my small rig.


    I have been trying to setup a good Metallica tone. I am pretty happy with where i am at so far, so much so that my Mesa Flux Five pedal is now for sale. The AFB tones are at least as good after only a few hours of fiddling. So far i have the EQ section set up as follows:

    I am using the "Marc IV EQ" amp.

    There are 5 "post" bands in the Mesa EQ so i have had to be careful about how i setup the 1 "pre" and 3 "post" bands in the AFB software.

    Pre - set to 80hz, gain only

    Post 1 - set to 750hz, gain only

    Post 2 - set to 2.2khz, gain only

    Post 3 - set to 6.6khz, gain only


    The missing frequency is 240hz, which according to the information i have should be set to 0db anyway.


    Does anyone have any input in the way i have set things up?

    Should i be using the gain only setting or another setting? I previously used the "notch" setting but had to raise the Q to 10 to get it in the ball park.

    The roll off on the pre is currently set to 20hz but the tone is a little flubby, should i raise the roll off to cure this?


    Essentially i have just twiddled knobs fairly blindly (i am still learning what all the parameters mean and what they do) and ended up with something i am about 80% happy with. Any input to fine tune things would be greatly appreciated.

    Setting the EQ to GAIN ONLY turns the EQ in to nothing more than a level cut/boost while ignoring all frequencies.
    You'll want to set the EQ mode to PEAKING. This gives you access to boost/cut, frequency selection and Q width.
    A parametric EQ basically.
    Sadly the AFB doesn't have a graphic EQ block which would make things easy for you.
    But keep in mind that the MARK IV EQ amp model was modeled with the graphic EQ ON with a standard
    smiley face settings. Boosting lows and highs while cutting mids.
    The MARK IV LEAD model is the same, but modeled with the graphic EQ off.
    For the PRE ROLL OFF, start with it set to 250Hz. If that cuts too much of your low mids,
    start setting the value lower. Don't go below 125Hz.
    Here's a link to a Tone Tips document I made that should help you dial things in better:

    Thanks for your reply Jace.
    I’ll try your suggestions tonight.
    My experience with the 2 different Marc IV amps is that they sound basically the same. The lead amp has maybe a touch more gain.
    I actually have the pre roll off set to 120hz at the moment. It helps tighten up the bass a bit.
    The Mesa GEQ settings I am trying to achieve are:
    80hz - +2db
    240hz - 0db
    750hz - -6db
    2.2khz - -2db
    6.6khz - +2db

    cheers
