Today I lowered the saddles on my 4 string bass and I can't believe how much better it feels to play. My only concern is my naivety in doing this. It is the first time I've played around with them so I'm fully aware of the implications of my actions. I managed to get the strings tuned up pretty well after that as I noticed that they went flat after lowering them . They also went flat when I moved the saddles back and forward. I looked at several pictures of basses and the saddles were positioned with the E string furthest back, then the A string a little bit more forward and so on. Is this for a reason? I copied these positions (roughly) but the intonation is out on some strings and frets. Have I done something I shouldn't have? I prefer the low action and as long as it is in tune then I can't see a problem.
