Check the listing for details. Pearl BC830 Cymbal Boom Stand with Uni-lock Tilter. Color: Silver, Condition: New. Listed at 104.99 USD. Pearl's Cymbal Boom Stand with Uni-Lock Tilter has slip-proof positioning and no chance of that distasteful metallic sound when playing. This stand features the uni-lock tilter that has a built in percussion post and a reversible cymbal cup that allows players to control the range of motion for the cymbal. This means the cymbal is highly adjustable and will lock into place easily. There's also a quick-release nut that makes cymbal changing easier than ever because of a boom tilter with a form fitting stop lock that gets just the right angle. The die cast pipe joint uses nylon bushing so there's no metal on metal contact! There's even double-braced legs so that everything is sturdy and secure for even the hardest of cymbal hits.
