Girls and boys, need a couple recommendations for BEFORE THE AMP noise gates. I run an old 50 watt (1981 I think) JCM 800. No FX loop on the back, of course, and I don't want to start farting around back there, it sounds great as is. Could use a gate when I've dimed everything and have a OD or boost pedal or two going. I am thinking of trying a Fortin Zuul but could also use a rec for something that's a little more binary. Thanks.
