If you want more distortion that will work. The only other thing I would change is C22. You should increase it by the same factor that you decrease R42. So if you halve R42 to 22k, you should double C22 to 0.1u, or if you make R42 4.7k, C22 should be 1u. The reason for this is that the capacitor makes the op amp act as a high pass filter. With lower frequencies its impedance is high, which reduces the gain of the op amp stage. The cutoff frequency of this filter is 1/(2*pi*R42*C22), which is 72Hz with the original values. If you halve R42, you double the frequency to 154Hz, which will reduce bass. So to keep the cutoff frequency at 72Hz, you need to double C22.
If you want to know this stuff without asking, you really need to know the theory. The best ways to learn that is to read about it and ask lots of questions. So keep asking questions until you feel you don't need to anymore. It's still worth it to simulate, breadboard, and build your ideas to get a more empirical understanding of how they sound, and you should do a lot of this too so that you can apply theoretical knowledge to practical applications.
