Alright first off you are going to need two things. You need a good punchy kick, and a bass sub/808 that you can manipulate. I usually use either Kontakt (808 warfare) or an 808 patch out of massive. You could also use serum, another synth or even samplers (I've seen a few of my friends use this also.) If you aren't sure where to start, I would probably suggest picking the kick first, although there is no right answer. Play your kick and 808 patterns, they don't have to

So you just got this awesome sample, you made a great bass line, but one problem, the sample has drums. (Making it sound muddy/off beat/off/etc) The first step is to rewarp the sample, I will give a quick example in Ableton. Make sure all the main down and up beats hit exactly on the line, if not you should add a warp marker (double click) then move it. You may have to adjust in between notes as well, start with quarter notes first though, then work to eighth notes. Also
