simple slide build. mahogany neck with walnut fretboard. I set the string action @ 4mm to top of all strings and kept the square profile on the neck with a 1/2" round over on back. For me this seems to help keep the slide straight and square. A humbucker in the neck position with a .047uf tone cap and volume control. The plastic looking thing on the corner is a Kid Kusion corner guard I picked up at Walmart. This box has the sharpest corners of any I have built and 6.5" wide it was digging into my forearm, so this was a simple fix that actually works pretty well.
