    TUBE PRE: based on a generic preamp tube

    This is not the model of a guitar amplifier. It’s a generic model of a preamp tube (model: Ideal Tetrode), completely neutral and low-gain.

    You can this model to “warm up” a source, such as an acoustic guitar or a synth.

    You can also use it to operate as a poweramp-only model. For example if you want to use a physical preamp pedal with your AX8 or Axe-Fx II.

    Cliff's comments:

    "The Tube Pre model is neutral. The "Vintage" tone stack is flat. The Tube Pre model uses the Vintage tone stack. The Vintage tone stack is a passive EQ model but it has a flat response when the controls are at noon. If you want "active" EQ you need to set the type to Active.”​

    "If you only need power amp modeling, for example when using an external pre-amp through the Axe-Fx, use the Tube Pre model. It uses the Vintage tonestack which is flat when the tone controls are at noon."​

    This "amp" is great to warm up some vocals!

    I always use Tube pre for bass. Also for recording. I like it better than any of the bass amps in the Axe. I also use it for acoustic guitar and my sitar. I always use it without a cab block.

    I wonder however if the Tube pre is completely neutral? I think it does color the sound.

    The tone stack by default is neutral.

    The preamp model and power amp model do add color.

    Yeah - good for vocals and bass. Preamp saturation in the cab block also great on vocals!

    I use this model a lot. Both for acoustic but also for those ultra clean straight to desk funky guitar tones. I believe Chic's Le Freak and the rhythm guitar in another brick in the wall was recorded like this.

    I actually thought, it was the input stage of a tube driven console or a generic tube studio preamp that was modelled by this one. I guess I was a bit off on that one, but I still love the model.

    Aaaaaaah, the beloved Tube-Pre.
    Tube-Pre is at the center of all my acoustic presets.

    Love me some Tube-Pre. And a lot of Reverb.
    Oh my!

    Tube pre or not tube pre. That is the question.

    Each amp model has a tone stack. They can be interchanged with each other to create custom virtual amps.

    Ok, so what are the settings to get is as neutral as can? What can I do? Set gain to 0.5 and set preamp bias to 0.0 and so on?

    Keep the tone controls at default. That's it. It's a very low-gain tube simulation. It doesn't create distortion.

    Well, not much, anyway. There's a little bit there, if you dial it in. Sounds more like "fattening" than distortion.

    Edit the Amp and change TONESTACK TYPE.

    ...which also makes some fun when you just play around with that parameter. I love it, I get different versions of my sounds in an instant.

    ok. I though bathrecords meant something else with creating a custom virtual amp
