Beater Upgrade Kit

The most requested upgrade to The Miller Machine.

Upgrade any existing Miller Machine to hold one of these new custom designed solid body beaters.

The Beater Upgrade Kit comes with either a 5/16" Brass Beater for your Triangle Machine, or a 5/16" Steel Beater for your Finger Cymbal Machine.

Along with the beater you'll also get all the pieces and parts you need to convert any original Miller Machine to hold these beaters.

If you already own a Grover Pro Miller Machine (thank you!) you won't need this.

Don't forget to select either a brass beater (for triangle) or steel beater (for finger cymbal) below.

Use Most Beaters

The Beater Upgrade Kit also makes it possible to mount ANY triangle beater with an 1/8" shaft on any existing Miller Machine.

This means you can use any size of your favorite Black Swamp, Dragonfly Percussion, Freer, Grover Pro, Stoessel etc... on your Miller Machine.

Built by Hand

Everything's designed and built by Billy Miller in his workshop in Seattle, Washington.

"Thankfully, the new beater upgrades arrived just in time to use them on this run!

I knew the upgraded beaters would be better, but I was really surprised with how good they sound! I still play the triangle by hand when I can for more control, but the sound between my Stoessel beaters and the brass beaters with the upgrade is nearly indistinguishable."
