i don’t think the 18watt is the right amp to achieve those types of tones. That type of tone is achieved with 4 preamp gain stages + CF before the PI. With your sIII you have a single gain stage on the traditional channel and 2gain stages + CF on the TMB channel. Play
Escape Road now. There is a reason why Mike Soldano went with 4 gain stages in his SLO. Up until that point heavy tones were to be had by putting a pedal in front of a JCM 800. So what you had was a gain stage in front followed by warm bias then cold clipper then warm bias again. Soldano got rid of the pedal, added a gain stage and moved the cold clipper to the third stage. Other amp companies followed suite .. in fact directly ripped off his circuit. You will need that type of amp.
You're right that the 18-watt amp might not give you the high-gain saturation typical of bands like Deftones or Metallica. To achieve those modern, heavy tones, you'll likely need to consider amps with more gain stages, similar to what Soldano did with the SLO. One option could be to upgrade to a high-gain amp like a Mesa Boogie or a modern Marshall that has multiple gain stages built in. Alternatively, you could use a good overdrive or distortion pedal in front of your current amp to push it closer to the heavier sounds you're after.
