The Stew Mac Scissor jack is really cool, and pricey. It would be cheaper to take it to a Tech.
Check your Tuner Nuts, change the strings and make sure the ball ends are seated properly. You said you just refretted it. Does fret height check out with a Rocker tool? THEN chase the buzz in the body. Get a telescopic mirror at Home Depot. Shine a flashlight and look for gaps. When (if ) you clamp make sure you use something between the clamp and guitar to keep dinging at bay.
Good luck finding your buzz
BTW High and Dry was my first finger picker tune.
