the drawmer is pretty cool. i have used the 1960 a bunch (the version of the 1968 that has mic pres in it) and it is cool, but not what i would call a go to bass compressor... compression is so specific to style...
i am a big fan of the DBX 160A or T or XT... the simplicity of them, high quality of parts, and tone are all great for bass... they can sound a bit 'pinched' with tons of gain reduction happening, but for light compression, they can sound really round and nice.
my favourite all around is a nice 1176. we have 2 of them at my studio, one of which was modified by purple audio, and that one is amazing on bass... it is really tight and 'rigid' feeling. the flexibility of an 1176 is unbeatable, and for me, that makes it my desert island compressor for bass.
LA4 can be cool, too.... it is very transparent, but can be a bit grainy... good for aggressive rock sounds that need to be controlled dynamically.
as far as flat out tone goes, i have a federal am864/u that is totally killing for bass. it is smooth, deep, and the time constants are pretty much perfectly matched to my playing. it has one knob, which is the input gain, so this thing either is perfect for your playing and tone, or it isn't....
also amazing is my Gates Sta-Level... it is very similar to a Fairchild 660... the particular 6386 based vari-mu compression of this box enhances low frequencies in a really nice way, but sometimes it is too 'pretty' sounding... more of my go-to vocal comp than bass comp...
i would stay away from any cheaper rack compressors, like the dbx ones with a billion knobs, because generally they are IC fests inside, and don't really improve tone..
i look at compressors as devices that not only affect the level of an instrument, but affect the tonal color of it... different time constants, make up gain amp designs, and transformers all create different compressors that can be chosen for their tonal imprint, not just their ability to 'control peaks'....
but yeah, compressors are fun.
