When it comes to constantly setting up and breaking down drums gig after gig, night after night, memory locks are a huge life saver for drummers of all levels. Used to keep a player's settings on their hardware, these simple clamps help drummers 'set and forget' specific heights and angles on their stands. Not only do they keep settings at a desired place for players, they also provide stability keeping various parts from slipping or turning into an unfavorable position. No more trying to mess with a cymbal stand or boom arm over and over trying to find the desired setting every time you set up to play.
