I got a Behringer copy of a Boss NS2 for $15 at a pawn shop. Now that I know that it works for what I want it to do. I'm ready to invest in a final solution. My final considerations are: TC Electronics Sentry. Boss NS2 ISP Decimator II G-string It seems like the TC and the ISP are both getting better reviews than the Boss. It looks like the TC has more versatile controls but isn't as simple to use as the ISP. The one thing I do that's a little challenging for a noise-gate is occasional low-volume background playing during oration. I need something that will let me use lower volume without cutting out. Does anyone have any good advice or experience to share on this decision making process?
