OK - I finally broke down and bought an RNC based on all the rave reviews in and about this site. I tested the unit out on my Drum Bus - There was an immediate and very noticeable hype in the high end and the low end all but dissappeared. Anyone else have this same expereience? I know enuf to understanding that different settings will have an effect on freq. but I don't think that is the problem. Any feedback wud be appreciated, thanks.
