I realise that this question concerns strings, but I want to know what effect the strings will have on my bass. Recently, I've decided to try playing with lighter gauge strings - not dramatically so, because I use a pretty light gauge anyway, but quite a difference. To give you an idea, my G string is currently a 40, while the next gauge down is, I think, 30. I realise that this will lead to less tension on the neck - how much difference do you think this will make, and will it be safe to do so? Will I need to adjust the neck at all, or will I be able to get away with this?
