Sometimes heavier gauge strings can give more harmonics or overtones to the sound, which might make the your tone a bit "fuller"... Or adding a bit more middle to your EQ should give more definition. Not sure what you mean by a "bassy" sound!? Do you just mean roll all the top end off, or set all the bass/low-mid knobs to 11?! Its all very well flapping your own trousers, but if there is no definition to the sound nobody will be able to hear what you are playing!
