Anyone here have any experiences with these? I bought one used last weekend & put it in the fx loop on my MkIIb with my US made '57 Strat R.I., it defineatly took out the noise from that guitar, but I found that it took away some of the top end sparkle as well, (That might be corrected by putting a BBE Maximizer at the very end of the chain) & took some fiddleing to get a good sound. But I guess there is a trade off, my sound overall sounded more defined without all that hum & hissas well as it seemed to take away alot of the string scratching noise away too, made my playing sound cleaner. I have yet to put it in my MkIII's fx loop. I also used it for laying down some bass tracks to take the hum out of my Mexican made Fender Jazz Bass, by pluging it in before the board and after a Avalon tube eq/compressor that I was useing as a preamp. I've read the reviews on Harmony Central & they seem to be pretty favorable of it. Is there a better noise gate out there? I may want to buy another one as well.
