The text describes how to achieve Zakk Wylde's signature guitar tone from his time with Black Sabbath (not Ozzy Osbourne or other bands) using a specific combination of equipment and settings.

To recreate this sound, you'll need:

1. A Marshall-voiced amplifier (preferably an JVM100H)

2. EMG 60 humbucker pickups

3. Boss OC-2 Octa-Crusher Pro pedal

Set your amp as follows:

* Bass: around -5 to -10 o'clock

* Mids: around noon or slightly below

* Treble and Presence: turned down, but not all the way (around 8 o'clock)

Use these pedals in this order:

1. Boss OC-2 Octa-Crusher Pro pedal:

+ Distortion/OD section: drive set to about 6 o'clock, color set to 'midway between 'medium' and 'heavy''

* Boost section: gain turned up, but not too high

2. Marshall JVM100H amp:

+ Gain: around 7-8 o'clock (depending on the guitar being used)

+ Presence/Presence/Bass controls: all at minimum

In addition to these settings:

1. Use a Les Paul or similar humbucker-equipped guitar with EMG pickups.

2. Set your amp's EQ so that it sounds 'midrangey' and not too bright.

Keep in mind that Zakk Wylde is known for constantly changing his equipment setup, so this may not exactly replicate his current tone.
