Any Boss NS 2 Noise Gate owners out there ??? Do you know if this sleek sexy pedal can get rid of hiss caused by boosting treble ???. I just got a Boss EQ 20 , and whilst I'm more or less satisfied with it , boosting treble seems to create LOADS of hiss in my Ashdown EB 150 combo. Can the NS 2 'cure' this ?? Or would a different noise gate be better ??
