Hi. Can someone tell me which guitars are real 24 fret guitars and which are just 22 fret guitars with 2 extra frets added on?
I found that this gives a Black Sabbath-y tone.

7 - 8 Gain (called Drive on some amps), 3 Treble, 5 Middle, 6 Bass.

Just mess around with it. High gain, low treble, medium to high middle, high bass should give you a good Black Sabbath sound.

Good luck.

what are the best amp settings to get a decent black sabath sound?

Just mess around with the EQ knobs until you find a tone that sounds like it.
Since you didn't mention what amp you have, this is all the help I can give you.
