It looks pretty maxed out to me as is.
VR3 controls the gain of the first and third stages simultaneously and it's already pretty large (250K).

R35 controls the gain of the second stage and it's pretty large as well at 270K.

I suppose you could try upping R35 to 470K but I don't know if it would make a difference because I don't know how much more gain that stage is capable of producing. If it does work though, and gives more gain but the sound is a little ... duller ... you would then replace C22 with something like 47pf or 33pf to get a similar frequency response, albeit with more gain, to the original circuit.
