Steve Weiss are a percussion supply shop on the north side of Philadelphia, who specialize in concert percussion, and over the years have made industry connections that allow them to have a house brand of percussion and percussion accessories, called Liberty One. They have some very nice designs!

Here's a Liberty One Roto-Tom in the totally outrageous 18-inch diameter.

And it comes with a stand!

As usual, the pitch changes when you turn the drum clockwise (pitch goes up) and counterclockwise (pitch goes down).

Very nice shape, though that Hydraulic makes it sound like bodhran; it's a very dark sound.
