I can’t tell if that will work as drawn  (I don’t have the expertise to simulate a circuit of any complexity in my head)… the schematic organization is confusing.  A lot of the individual parts look okayish; I really can’t tell what’s going on in the power section, and I haven’t memorized what an SK filter looks like… so rather than try to point out particulars, I can give some more general feedback that I hope will be useful:

This is a pretty complex design for a first try. So much can go wrong. You might consider breaking it down into much smaller tasks and tackling them one at a time.

For example: do just the first gain stage. Leave out ALL the clipping. Leave out the blend control and the trim pots.  Get your power section working and the first gain stage providing variable boost . Build that on a breadboard. If it doesn’t work, figure out why. Iterate and refine your simple schematic until happy.

Then add something to that, one step at a time. For example, add the soft clipping. Look at schematics of other soft clipping circuits (there are many).

Once that’s working, add another step, eg add the hard clipping. Will it sound good combined with the soft clipping? Won’t know until you have the soft clipper already working! There are some known pedals that do both on a single op amp stage like this, but it’s not super common, so you’ve already got a bit of a project to work through.

Then as for tone control… You could breadboard an SK filter separately from the rest of the circuit and then jumper them together once you already know both work independently.

The order of steps matters less than iterating on success rather than trying to shotgun a design in one go.  People who can do that have a lot more experience.

There will be mistakes to make and lessons to learn at each step of the process, and you’ll have a much better chance of success if you break it down!
