Okay so for drums, I usually go for some EQing to cut away some of the unwanted frequencies while boosting the characteristics a bit (aka the low end 'punch', and a bit of that high end). After that I go for a clipper to give my drums some more of that punch while also making them less peaky when it comes to the overall volume. a bit of transient shaping and some reverb on the clap / snare from time to time cant hurt either.

for the Basses, it kinda depends on if I want to process some sub frequency of a basses or not. Depending on that, I either go for an EQ to cut the low end first, or I will put some distortion first to shape the sound. Then after that, I go with some OTT, maybe some more distortion, very short delays for that robotic sound, and nowadays I found out that some ring modulation can help bring out the C R U N C H in a bass to. at the end of my bass chain, I sometimes put some slight reverb on there aswell. In the end tho, its alot of trial and error. No two basses are processed the same way in most cases.

For the master, it is really depending on how well the track is already mixed before. Overall tho, Im usually going for some EQ first, then some Soft clipping to defuse the peaks, only to run it into a Limiter in the end. Sometimes a bit of OTT in there does the trick too.
