cycles: old wood material (producal the best)

i’ve checked around the posts and i could find anyone that has old wood mateerial in cycles, it’s the kind of wood you would find in a montain/forest step.



there isn’t much colour change when the other ones that i’ve seen are all about the colours, this one is about the displacement which creats the gaps of darkness in it, i could have a displacement modifier but i’d rather to use the material side for first consideration, there are still some lines of darker colour, but they are much more thinner. in the pic, there is much less gaps but in mine i would like more.

i tried to use noise texture, and the use the mapping node to stretch it then continue onwards, but nothing is working when i plug the mapping node in, it becomes a plain colour.

i’m using it for: an forest table, wooden planks over a swamp to walk, step blocker

please help
