as mentioned above, an EQ is nothing else than a bunch of filters (it is a "filterbank", although the term would confuse too many people). that's why EQing and filtering is exactly the same thing.

My question is how to make a sample containing bass and make it without bass so that I would be able to lay my own bass lines over it.
please try to word your question correctly. what you are saying doesn't make sense at all. you say:
1. make a sample containing bass
2. and then make it "without" bass
3. to put your own basslines over it.
why do you make a sample containing bass to make it "without bass" in step 2 ?! why don't you simply use a sample without bass directly?
and who says that you need samples "without bass" to put basslines over them ?!
but ok, i'm sure you meant:
"how do i erase bass of a sample?"
or
"how do i seperate a sample into two frequency bands?"
and since you said that you know what EQs and filters are (which i doubt), you must have meant the last one, so:
basically, you can simply duplicate your track (or midi track when using a sampler) and low-pass one, high-pass the other and mix both together.
but keep one thing in mind: that technique doesn't really make sense in most cases. even if splitted perfectly, the result will not be different from anything you can do with an EQ (except you want to process them independently with complex effects).
it's basically impossible to make perfect "summable", bit-transparent frequency splits at the "user-level" (a vst programmer could do it) - it's simply too complicated to grasp the math and the normal "user" doesn't have the tools needed for that. remember the thing called phase-distortion that happens during filtering? that's the problem here. a naive split like mentioned above will erase many frequencies in the mids (summing both splits will not be the original signal anymore).
anyway, select/create the sample like you need them at the first place. don't waste time on such complicated and worthless techniques - use that time for a better sound selection.
