The guitar & pickups play a role in your sound as well.
It looks like these guys use EMG-81s on mahogany body/neck guitars.
What's yours?
Also, here's a tip from Cliff:
Here's a cool trick to get very "tight" toanz:
1. Put a filter block before the amp block. Set the type to Highpass.
2. Attach the Envelope controller to the Frequency parameter. Use default settings for the Envelope parameters.
3. Set the Scale to 40%, Offset to around 22%.
4. Go nuts.
Here's another tip from another dude with the username "mniel8195".
I have found a that cranking the tube bias is a great tool for high gain amps, by raising it to taste or all the way on some models and lowering the master volume you can get extreme metal tones. I have also found by doing this i can keep my gain around 5 and 6, i was trying to go up to 7 for my distortion and crunch but the amp models would just crap out on me.
So my rules for any newcomers looking for brutal tones
1. Keep the gain at 5 at first, check to see if the boost is usable or not, i find that it will make the tone more satchurated and is often not need.
2. Use a od before the amp, my main od is the 808, gain 0 and level between 7-10
3. add treble to a preset before using the presence. Most of my patches are set to noon = 0 The presence control can actually deplete the quality of bottom end in the patch.
4. I know i have asked this alot and its a big topic, "how to get tight bottom end" The best way to do this is just to lower the bass on the patch.
5. mess around with the tube bias you may find you like it cranked.
6. Mess around with advanced perameter like sag and depth last has always worked best for me.
Search for more on the forum, there are lots of nice gems to find.
Hope that helps.
