I was thinking of redoing my bass, since I kinda rushed the sanding/finishing process because it was my first built and I just wanted to play it. So, some of the sides on my bass are a bit rough. I have a power sander(a hand held flat one) and it sucks at taking out large amounts of wood Ive seen people use belt sanders to carve tops etc, It seems to fit the bill nicely, as I can take out all the nicks with the belt sander(had held aswell) and then make it nice and smooth again with sandpaper/powersander. is a belt sander actually more powerful than a sheet/powersander also, can you use a belt sander to do contours? or do you need a spokshave/router/angle grinder for that?
