Ah, seeing the circuit again I should have sussed the model better! Thank you.
Have you also changed the components associated with the Tone Control as it should give quite a good range of "Cut"? Also removing the "Loudness" feature, will also have a sonic effect on the Tone Control at certain volume levels. I would try to re-build the ganged Pot if I were you. Be aware that this amplifier is rather intolerant of the most well-intentioned circuit alterations.
