Hi, I’m Danny Wolf and I’ve spent over 20 years as a professional drummer and recording engineer, touring around the world and playing on thousands of recordings. I've also ran my own recording studio, so I’ve spent a lot of time thinking about tone, gear, and what actually makes drums feel good to play.
Drummer Wallet started because I was tired of my wallet sliding off my snare so I built one that connects to the rim and actually stays in place. Later, I turned it into the Drummer Wallet 2.0, which works as a wallet, drum mute, and practice pad in one.
DedHeds came next. They are custom drum heads designed to control tone and resonance in a simple, musical way, without killing your drum or covering it in tape and gels.
Today, I’m building a growing line of drummer-focused tools and accessories designed by a working drummer, for working drummers.
Everything is designed with real playing in mind. It’s been amazing to see drummers around the world using these products, and I hope they make your drumming life a little easier and more fun.
