My experience is that a Rhode NT1a is quite bright. I borrowed a friends and for me it was all about positioning the mic.
If you are using the piezo as well as the mic you are probably getting some comb filtering owing to the waveforms not aligning. You might have to move the Piezo wav back until it lines up with the mic wav. This is because the piezo signal arrives fractionally in front of the mic signal. Two mics can cause the same problem if one is further away than the other.
Mic position facing the neck is brighter with more fret sounds - Level and above the sound hole is bassier and below is slightly brighter. A piece of plywood or hardboard under your chair if the room has a carpet can add a useful amount of presence.
The further away the mic the more room ambience which can be good in a larger room and not so nice in a smaller room.
Unfortunately, like anything, it takes a lot of experimenting with positioning and eq to get where you want to go.
