Hmmm... not sure why its not working for you because IMO there is absolutely no contest between Hybrit and the Stealer (Hybrit sounds really grainy and the decay is not very natural IMO). The stealer is arguably the best software marshall sim in existence. Its better than most of the hardware sims IMO as well. The kemper and AX probably have the advantage but I don't have those boxe$ lying around to compare. As far as tips go. Make sure you pay close attention to gain staging with S-gear. You want to keep your interface input at a level where it is NEVER in the red to avoid digital clipping. Also you want to make sure that the output level from S-gear is also never in the red for the same reason. However...You typically want the input gain within S-Gear to be HOT. If its too low it'll sound anemic. You can adjust this within S-gear using the input trim knob. The input meter in S-gear should be averaging near the top of the green section and into the yellow. It is NOT an issue if it goes into the red. It'll react like a real amp when pushed into the red and get dirtier without digital distortion - only more simulated tube distortion. I use a VST treble booster or Tube screamer plugin to boost the front end of the Stealer into the red and it sounds awesome just like it does with the real deal. Experiment with all of the boosts on the stealer and also spend time getting acquainted with the contour knob which is basically a tone/distortion control that simulates a jumped marshall where you can vary the Bright and Normal channel volumes for different sounds. Contour full CCW = normal channel only; Full CW = Bright only; Fun can be had everywhere in between.
