HI guys, some of you might have already seen my build, it's a 7 string ash explorer, my first project guitar, back then I had no idea about guitars and felt like I rushed this project, any way the finish is a bit messy, i've changed the nut to bone nut and adjusted the truss rod, now it plays pretty well. I've just ordered a sg f1 kit hoping to start on the project next week. Got one question regarding the SG kit, do I sand the top vertically or horizontally? Coz the back would have be sanding vertically for sure aye?
