Re: Sonor Perfect Balance not sitting flat on ground...
Yup. Double layer carpet made it uneven just enough to mess everything up. My bass drum was pretty much perfectly straight with about a finger-width of space between the floor and the front side. The single post on the pedal still wobbles when playing, but that's probably to be expected. (or just because I don't have a flat hoop, and I don't want to over tighten the clamp)
