Cello and Bass floor anchors
Cello and Bass floor anchors do just what they say – they go on the floor in front of you and anchor the cello so it doesn’t slide away. Generally speaking there is no advantage of one over the other except that some require a chair to anchor to. If a suitable chair is not available, one with a rubber backing is recommended such as the Blackhole or Viva floorstop. If you regularly play on a long pile carpet, an anchor with a strap is recommended.
A recent development in floorstops is the resonator chamber which also enhances the sound.
