which one of the noise reduction from the Zoom g2.1u is best for getting rid of feedback.

here are the 3 types of noise reduction built in to the pedal

nr ZNR (ZOOM Noise Reduction)
ZOOM original noise reduction which reduces noise in playing pauses without affecting the overall tone.


Gt GATE
This is a noise gate which cuts off the sound during playing pauses.


dG DIRTY GATE
This is a vintage type gate with special closing characteristics.


thanks

dG...started using it today

sucks out quite a bit of tone of set high but takes off a lot of feedback
