sorry about the autocorrect..."dynamic" range.I know what it does, I’m just not sure I can hear it doing it! Your reference to a Mediterranean spice plant have lost me……………..
Too many people are expecting some dramatic, grossly audible difference. Liek I said before, compression isn't going to give you dramatic results like say, a chorus, OD pedal, delay pedal, but because it's in the same form factor as every other pedal they think they're being ripped off because of the lack of an obvious change. This brings me to my original point of this...if you don't really know what the pedal is supposed to do, you aren't going to be able to appreciate what it does.
Saying you know what it does but can't hear what it's doing just means you really don't know what it does and/or how to use the pedal properly, or you're using it in a way that it's not going to be of benefit to you or your playing style, which then lead to the question being asked...why did you buy it in the first place?
