i agree with what aschleman said.
just relying on distortion alone wont get you too far. A slight delay with a little reverb gives a great embiance. Also with what Superhuman said... your settings are very important. I'd reccomend sitting down, putting all the knobs at 12 and play around from there. with my guitar (SG) Ive found I'll get a real round and full sound with some nice punch if I have my Highs on 8, Mids on 4.5, and Lows on 7. I'll usually always play on the neck pup, or at least on both, but usually with the neck prevailing. and try rolling down the tone knobs like aschleman said. I never roll mine all the way to one, but usually like at 6 sounds best to me.
as for modulation effects... I really like using detuning. my Digitech GNX3 has a great detuning effect, and I just like how it sounds.
play around and see what you can do with what you have, but I throw in another vote for getting some effects.
