Ralf! Holy cow, but you're good! I bought that damper control for the 13" tom back in the mid-eighties. Nothing wrong with the original, just thought this one looked "cooler". And you know how it is, you're 16, you're working as a dishwasher, you go into a music store with five bucks in your pocket, and you've got to buy something! Plus, already got a juice harp, slide whistle, and pair of claves.
So, I did a search for Star Drums One touch and, sure enough, that's it. The knobs on the floor tom and snare are still original.
The clamp on the 13" tom was needed. The original kept drooping, and the tom, hitting the snare.
