Well, let's put in perspective- silence at the right moments is indeed golden. My set up has plenty of drive coming from both a pedal & the amp's dirty channel. I've been through many noise reduction units & deem them all as practical. Useful is a matter of application which is largely personal. The purpose of having a noise reduction unit is to eliminate extraneous noise from your playing; all those background humming, hissing, pick scrapes & accidental picking could all be hushed. The understanding of silence here is when you stop playing, these noises wouldn't be heard. We need to understand that the extraneous noise cannot be eliminated to begin with but can control when they should not be heard.
Any down side of using a noise reduction unit? Yes.
- affects gain
- affects selected frequencies
- affects sustain
However, these setbacks are only apparent if the users are not objective when having a noise reduction unit in their set up. For instance, if you max out all the controls without understanding what each does, you are going to suffer the stutter effect; some lightly picked notes failed to get across the noise threshold & got muted. You also need to do a needs assessment- do you need a noise reduction unit especially so for those observing a low drive signal chain.
