Hi,

Is there anyway to mod the MP573 to be able to turn the volume to zero?

When I drive the unit into distortion, I can't lower the volume enough to prevent my converters from clipping.

Thanks

You need to replace R21 by a lower resistor or a wire.
But of course this will change the +10/-10dB law.

Hi!

I'm interesting in this possible mod.
Which behaviour would have the volume trim if change the resistor for a wire? Zero attenuation in "+10" position and maximum attenuation in "-10" position?

Thanks in advance!!

+10 will stay the same and -10 will become "full attenuation".
