You will probably wreck the 12AX7 in this circuit unless you adjust the cathode resistor or the grid bias resistors. The 12AU7 can take 10mA current where as a 12AX7 will withstand only 1/3 of that current. The 12AX7 sound is most likely full of the even order harmonic distortion that an underbiased tube has, which is why it will sound both pleasing and distorted.
