This is the same GS007 throwoff that you have come to love! The only difference is from time to time we get throwoffs that do not pass our high quality standards. These particular B Stock items function fully and properly, however, they will have some cosmetic blemishes, scratches, discoloration or mis-logo that we choose not to move as A stock to our vendors or customers. So, for a short time we have decided to clear out some of these items for an extreme discounted rate!!! Launched to critical acclaim and immediate adoption by the world’s leading drum makers, Trick's GS007 is the most advanced throw-off mechanism available today. The GS007 is the brainchild of Trick's chief engineer Bob Szwaya and manufacturing specialist George Szwaya. Close-tolerance CNC machined components suspended in a special synthetic lubricant give the GS007 its effortless and fluid movement. To increase resonance and reduce the amount of material touching the shell, the GS007 contacts via two very thin rails which keeps the remainder of the body elevated. We have employed the same philosophy to our butt end component as well.   Our GS007 Throw offs are designed not to slip or fail. They provide the user precise control of snare tension.   Protected under U.S. Patent Number 6,846,978,The GS007 is manufactured in total from solid machined metal parts consisting of billet aluminum, stainless steel as well as hardened steel. Trick's cam operated, helical groove design provides the user with the smoothest, quietest, most durable and road worthy throw-off ever made.
