From the post
Surprised this one hasn't been done. A nice small and quick build, and should have lots of boost on tap and fatten up your tone nicely. Could be a good platform to mod to taste. Seems to be on the rare side to boot. Only video I could find was a DIY build that has some mods, but you get the idea.
