It matters little as it seems there is little difference between schematics.
I'd First change the first stage to a *Follower* and leave the De-emphisis filter in place for now.
Work in stages until you find the balance,, if you change it all at once you have no way to know which mods worked,, some may even make it worse. work in small steps.
As to all the pretty coloured extra mods I'd leave them as last resort.
Understand this simple reality; Quite often noise issues are due to poor design NOT the quality or performance of Active components. In most cases using exotic chips achieves little.
If folks spent as much time learning RC maths you will come to realize how daffed this Mod with fancy parts game is.
I have more tone control from crap cheap gear than some of the big name pedal boards.
Why ? because I paid close attention to grounding and just where to bump up the gain.
Do it in the wrong place and noise will drive you mad.
My bet is this circuit is noisy because it has too much gain in the wrong place and if I had time to spare I could bread board test it to prove that but I would rather play my guitar
