Hey guys.....I tried searchin so as not to dredge up an oft discussed topic. But....I must have forgotten how to use the date range? I keep getting a "broaden search criteria" message? At any rate, I have an apparent ground loop hum. I can't remember the exact process but could probably fumble through ok. If anyone has an old post that would be great - and a piece of advice - are the standard Radio Shack isolaters sufficient or should I look elsewhere?..........Rob
