Hi Revoraman,

Anders' lesson on "Hotel California" features a "Gear and Tones" section. In this section, Anders mentions around the 1:17 mark that he's using an AC30 amp with a Tube screamer pedal.

Settings for the tube screamer pedal are as follows: the Level is set at 12 o'clock, Drive is at 2 o'clock , Tone at 1 o'clock.

He goes into more detail at the 1:17 mark here: https://www.guitartricks.com/lesson.php?input=17313&s_id=1304

Here's also a link to the first solo: https://www.guitartricks.com/lesson.php?input=17324&s_id=1304

I hope that helps!
