About 3-4 years ago, I bought 5 gates from MF to compare and see which I liked best and which I would be keeping. MXR smart gate, rocktron hush, ISP decimator, ISP g-string, NS-2. NS-2 won for me. People talk about tone suck from it a lot, but I never noticed it. I always ran it in 4CM so that it covered the front of my rig and the loop, and it sounded like my rig was off when it was on. Literally zero sound unless I wanted sound. I never had any tone suck issues until I did a mod on my Mak4 that Andrew suggested. With any other amp, no issues, and that included a 6505 and 5150 212, 5150 BL, 6505+, JSX, D60, Carvin MTS3200, and blue voodoo lol. The g-string is cool, but I think it needs a second knob, plus I had issues with it and the regular decimator adding hiss, and having to crank the knobs really high to get the kind of gating I want. The hush was meh. The smartgate was cool, but the fact that it doesnt run up front and in the loop was the deal breaker on that one. Ive literally been using NS-2s for 10 years and never once have I had any complaints, and I have yet to find a gate that I like as much as it.
