After all of the effects are on, go ahead and put a lowpass (or high cut) filter on the bass. REMEMBER: the filter has to be AFTER all of the effects. The purpose of this is to get the bass as clean and deep as possible, but make sure that you can still tell it's a "bass." After that, you can apply the decimator/bitcrusher. REMEMBER: the distortion has to go AFTER the lowpass filter, otherwise the distortion trick won't work. For my sound, I used a free vst plugin called "CMT Bitcrusher." I will also have the link for that too
. You can now mess with the settings on the distortion to get it just how you want it. Remember, certain settings are going to be dirtier than others, so you might have to turn the nobs a little to find the right area where the sound is distorted, but clean. Hope that can help increase your knowledge of producing some sweet basses! 
Also, I would love to see what kind of basses or sounds any of you have made, so feel free to post them here 
P.S. my bass might sound a bit dirty, but it's because it's a saw wave bass and I didn't take much time to make it as clean as possible. Don't worry though, this technique is legit
