Set-Up Tools in DIY (Do It Yourself) Posted January 21, 2017 I remove the strings with my fingers then ensure the neck is dead flat with my eye. Then I lightly sand the frets with 800 w&d wrapped around a straight length of alloy out of my scrap bin to find high spots.Then I hit them or glue them down ,proof sand then dress them ,taking . a little bit more off each fret to the heel. Then a bit more w&d ,(1200) and some steel wool stolen from the kitchen Last of all I put a .5 wedge in the cavity. I only charge for parts . No complaints ever. Blows me away to see big name guitars leave the factory with action more suited to slide. Jems are constant patients .I once managed to fit a cigarette under the 12th on a floral. Players assume the Vai association means San Dimas-like action. This misconception is far from the truth and there,s not much that can be done. Theres no reason why guitars cant leave the factory with Charvel/Les paul playability. At the present silky action comes under the "custom shop" banner with a hefty price tag. I made some modifications to my old $300 Squire. It makes my Highway 1 look like firewood.
