Getting ready to buy a noise gate.  I record in a very small room and i literally have to sit 2 feet or less from my amp.  Feedback is a very big problem and its a 5150 so it hisses like a snake.  Ive been looking at noise gates to fix the problem.  Ditched the idea of the NS-2 as I hear its a tone sucker.  Do I need to get the decimator g-string if I wanna get rid of the hiss and feedback altogether or will the normal decimator do?  I guess I could always just run a software gate to knock out the hiss.  Should I be looking at rackmount options as well?  I kinda like the idea of a pedal, dual use, live/studio.
