"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."
