When I switched from my tube amp I got rid of my ISP Decimator as well thinking the FX Ultra would handle that job just as good and was really disappointed. I'm not saying it's bad at all, in fact it's good. But it's definitely no Decimator. It would be really nice to see an improved noise gate, perhaps modeled after the way the Decimator works, anyone that owns or has owned a Decimator can tell you that thing is the bottom line for noise reduction. I'm saving for another Decimator myself, but I would love to have something that competes with it in my Ultra. I'm sure a lot of the people here who don't live on extreme gain don't have any complaints with the noise gate but I can't be the only one who thinks it could be vastly improved.
