Includes 1 random style shaker + 1 mute. The Index Percussion Accessory (IPA) is the original steel can shaker made from vintage Beer and Soda cans from a bygone era. The 12oz is the standard size, and is perfect to throw in a stick bag. They are much more durable than modern cans, with thicker walls and a stronger shape. The SMOOTH flavor is much quieter than the HOPPY, and more suited for small venues. A great tool to have in your arsenal. This is on the softer side, but with the same metallic flavor. Similar fill to the ever-popular egg shaker. I've heard from lots of people that this is their favorite of the two, so it seems like an even split. You can go Random and let us pick you out a winner, or choose from some options in the dropdown over there. We recommend getting both flavors, of course.
