Found a lot of threads about the Decimators...both regular and G-String, but nothing that really compares the two. I am running a few pedals up front and a few in my loop. I currently have a Boss NS-2 that I have had decent luck with. Right now its up front killing the pedal noise, but I am getting some noise from the loop. I do want to try it in the loop to see if it will take care of everything, but I am really considering upgrading to one of the Decimators either way. I would be interested in hearing from anyone that has used both or anyone that has used the G-String in the config that kills the pedal noise up front and integrates it into the FX loop to kill noise there. G-String is a bit more and requires more wiring so I would like to avoid it if it is just not necessary.
