    Hello,

    I bought an Amplifire 12 a few months ago, and I've never been able to set up a good clean sound because it always starts clipping (or at least it says so, I don't even hear it).
    I have a high gain preset using the Mark IV model. Level is at 40%, level at 0db and most of the knobs are at 12 o'clock +-, with the poweramp enabled, and I don't get any clip warning.
    Switching to the clean preset (which is much quieter, and it clips like crazy. What am I doing wrong?

    I think I'm going to reset this hole thing to factory defaults. Could anyone walk me through setting it up? I'm either too dumb or too stupid to do it :)
    Oh, and by the way, the Amplifire had Ownhammer IRs preinstalled from the previous owner - will resetting it delete them?

    Thanks, greatly appreciate any help!

    Best wishes

    Hello,
    I suggest you download these presets that I made:
    https://atomicamps.com/forum/index.php?threads/new-stage-volume-presets.2705/

    http://atomicamps.com/forum/index.php?threads/stage-volume-presets-2.2706/

    These were created at stage volume and dialed in not to clip the output.

    Here are instructions for setting up your own presets not to clip:


    1. Turn on Amplifire, plug in your guitar. Do not turn on your monitor!

    2. Select your cleanest, least compressed preset.

    3. Turn the Amplifire output level knob All the way up (that's 100%.)

    4. Play your guitar with the hottest pickup (usually the neck) selected, the guitar controls all the way up, as loud as you can. Strum all six open strings. Play bar chords. Hard.

    5. Use the LEVEL parameter of the AMP block in the Amplifire to set your preset levels.

    6. Turn up the AMP block LEVEL parameter until the display indicates digital clip. Again, make sure that the Amplifire output level knob All the way up (that's 100%.)

    7. Now turn down that AMP block LEVEL parameter until you cannot create the clip condition, no matter how hard you play.

    8. Save the preset.

    You now have a “Reference Preset” for setting the levels of your other presets.

    For the next part, you'll need your monitor turned on, connected to the Amplifire, with its volume control set so you can hear sound. You do NOT need to set the Amplifire's level control to 100% anymore. Listen to the preset you want to adjust. Select your reference preset. Listen to it. Adjust the level of the other preset to get a match. Save your new preset. Switch back and forth a few times, play, and compare levels. Remember to save the level of the preset you're adjusting before switching back to the reference. When they match to your satisfaction, save the preset you were adjusting one more time. Repeat as necessary at your convenience.

    The above is my preset-leveling procedure, posted most recently on TGP ca. 2016:

    Gain staging my presets correctly

    The tip after Edit: in the TGP post is worthwhile:

    "When matching the level of a dirtier-sounding preset to your clean reference, it may help to do so with your guitar volume backed off a bit, so you're matching a clean(er) level. That gives you a little extra for solos and helps compensate for gainier sounds cutting less well."

    Thank you, I did that and now I have a clean reference tone. The amplifire is very complex, it'll probably take a while to fully understand its capabilities.
    I have another question. I'm trying to set up my delay/echo effect. The manual says that setting the tempo to anything but off will disable the time knob, but for some reason it still affects the duration of the effect. Is there any way to set the echo speed via BPM only?

    Home Page:
    As long as you select a time signature (1/4 note, dotted 1/8 note, etc)
    the echo should follow the BPM. On the GLOBAL page of the editor in the
    bottom left make sure the MIDI CLOCK is set to OFF if you're not sending
    or receiving MIDI CLOCK signals.
    Here are links to a couple of documents that will help you with dialing
    in tone and assigning foot switches. The unit is complex as you say
    and these will help you understand the unit better:
