Now once I go beyond 3 quarters on the vol pot the top of the waveform starts to clip quite harshly and I measured this in the preamp output so the clipping seems to be happening in the preamp even though the pot is at the output.

As it's been a while it might be worth posting the current schematic that pertains to the above tests.
