Agree with you @Painy and @4000
I like a super low action - but I find the most important thing is very little relief in the neck. This means I can play with a super light touch, and by altering the way I pluck the strings, and position of my right hand, I can go from a clear round note to a raspy burp sound. This has been married to the careful use of a limiter in my signal chain which gives everything a defined 'edge' at which point the clank cuts in.
I haven't ever measured my action but I like it lowww - especially the G string which I always have lower than the rest. Normally at a bash people pick up my bass and it's choking everywhere - and when I pick up someone else's bass I feel really slow and numb on it!
