I would like to make a fet version of all three channels in one box. And to use 1 switch to choose between them, i don't need true bypass. What kind of switch do i need for this?

You could do the switching with a three button footswitch and several relays, but it is likely to get messy. I did some switching using relays on an amp I built and, while they work well, coming up with the scheme can be very challenging. Unless you are really good at thinking through signal switching paths, I would say "Just don't do it, man!" Of course, you can learn a lot by trying to do something that you don't know and that is difficult. Good luck.
I guess it's going to be hard but i would like to do it. The easiest thing would be to use dpdt switch and clean + one of the dirt channels, but i would like to have all three of them and not just two. How about a three way switch with 6 lugs? Is there some article about all kinds of switches? Spdt, Dpdt and 3pdt are not the only switches out there.
You could use a rotary switch, that would let you select any of the channels, but obviously you can't stomp on that. If you don't want to use relays or some other sort of electronic switching, and want stomp switches, the best you can do is what you already suggested. You could expand that so you had one switch that selected clean or dirt and a second one that selected between the two dirt channels. This would let you go clean to brown or clean to sharp, and once you were on one dirt channel you could change to the other one or back to clean.
That is by far the best idea ( two switches ). Thnx, will try that.
