From the post

Original infos:

The Acapulco Gold is a dirt-simple power amp distortion device that's based on the vibe of a cranked Sunn Model T.

You know what is awesome?

Simplicity. One button, one knob. How loud would you like it?

Just move the knob.

This is the spirit of rock and roll. Quit turning knobs and play that guitar like you mean it.

While playing, you may want to try ignoring our suggestion and try fiddlin' with your guitar's volume and tone knobs as these can drastically affect the sound of the Acapulco Gold.

The volume knob on your guitar cleans up the pedal nicely, but not too clean.

At minimum guitar volume settings, the Gold imparts a hazy, Nashville-sounding spank to your tone. At just-barely-backed-off, the Gold turns into a raunchy overdrive.

And of course when the guitar volume is completely open, the Gold roars like a Model T on the verge of explosion. It's not quite fuzz, but so close.

This is a very loud pedal.

As Nocentelli pointed out on the original FSB thread here, there are 2 types of videos:

a carefully produced one from PGS (where it's probably used to massively drive a nice tube amp)

and a more realistic one where the volume knob is set much lower
