From the vendor

Have you ever seen one of those one man band performers with the bass drum on their back? It's kind of cool with how the bass drum helps keep the beat and can really flesh out a solo performance. If you have something that will do it for you, it also helps keep time and sounds way cooler than a boring metronome click. So I started looking around at analog kick drum circuits and found one that had some great sound shaping capability and decided I had to make a tap tempo kick drum pedal.
