It appears that a Fuzz-pedal would go a long way towards.getting the tone or sound I want, since both Robin Trower and DJ Ashba, whose tone I've more or less fallen in love with, use a Fuzz-pedal for their distorted parts, at least according to the videos I've found where they talk about their gear. Aside from that, they also both use a Marshall Tube-Amp, a Wah pedal and a Chorus/Flanger/Phaser of some sort (DJ Ashba uses a Chorus for his Les Pauls, not quite sure about Trower, but haghj500 suggested a Phaser, which would make sense to me, since single-coil pickups are a bit weaker than humbuckers, and require more gain to sound heavy). I'll have to try some of those effects when I get the chance, in order to see what works for me.
