Howdy!

I've a 2015 Marshall Silver Jubilee that I love but need it to have a bit more bite and aggressiveness. I love the tone but just need a more punch. Currently, I've the amp's gain cranked to 10. I'm looking for a classic rock on steroids type of tone. Kinda of Dean DeLeo's tone on Stone Temple Pilots Purple album. Gnarly and big but without getting into the metal territory. Any suggestions? Thanks beforehand!
