This is Pearl's drum throne, the top-of-the-line model at the time. The main tube has grooves and can be finely adjusted by rotating it. The holder can be detached with a single touch by loosening it. I used a different manufacturer's throne, so this one is almost unused. There is no wear and tear. I'm selling it to organize my equipment. I'm also selling a Noble & Cooley snare drum and a Ludwig single-head tom. Shipping will be via Sagawa Express, cash on delivery. This is a bargain, so don't miss this opportunity.
