My only regret in purchasing Bernie's Fret Dagger and Gauge is I didn't purchase the Fret File and the leveling blocks before I moved back to the Philippines. I set up my USA guitars before I left and am now working on my three Philippine purchased guitars; a Tompson Strat copy, and two guitars from RJ Jacinto's Guitar store, (RJ Guitars), one a solid body electric acoustic and the other a solid top nylon electric acoustic. Guitars here in the Philippines are dirt cheap, compared to the US, except of course for the name brands, like Taylor, Gibson, etc. which are about the same price as the US. Anyway, Bernie's tools are the BOMB! I'm a retired 73 year old nuclear engineer, guitar newbie, but I love to tinker, and Bernie's tools make the work so easy and enjoyable. It's nice to have good tools to improve the build of a guitar. I've found that even the best guitars have some bugs that slip through QC. For instance my Fender Tele had rough edges on the frets. Bernie to the rescue. Best
