To get a reasonable signal to noise ratio you have to wind the amp right up (which you can do with the headphones jack in) however as you turn up all the EQ changes.
I shot strait into my D1200 and had to turn the gain right up on the recorder after cranking the amp which ultimately lead to a crappy sounding recording.
It is however great with a large diaphragm condenser in front of it even at relatively low volumes.
