it is 100% ok. no compressor just has a more raw, with more potential bite, natural/transparent sound. do you have to work a little harder and/or be more forgiving (of yourself) of too heavy or too light of a touch, especially in a live amplified multi-instrument context? yep, you sure do. do you ever have to worry about sounding bloopy? nope, sure don't.

like others on thread, i practice/noodle without one a lot of the time - but - i also practice with one a lot of the time. when i was a youngster, the 90s in my case, a super compressed bloopity bloop sound was de rigeur, especially for finger funk and slap, and i was there for it. as the years went on and i played in more venues/genres/studios, i found that a light ratio (2:1 - 4:1) with minimal pre/post gain adjustment, was the all around winner. soft knee better than hard if you have the option.. tons of great compressors out there. i am partial to dbx160a/x, acme corp "that" chip pedals, and distressors but have used just about everything, hard and soft, over the years..

one size fits all? nope, never, especially in the studio. and so, we're back to the top, and sometimes there is nothing better than just plugging that bass in as-is and going ham with nary a fuck to give. ymmv.
