Several years ago, I bought the Donner DED-200 drum kit as a birthday present for my son, who had dreams of becoming a drummer. As you might predict, he ended up favoring the guitar and piano, leaving the drum kit to gather dust in the corner. That’s when I decided to tackle the set and bring it back to life. Because, maybe I could be a drummer. Why not? The problem was that the ride crash cymbal pad wasn’t working.

So I rolled up my sleeves and got to work. This was the second problem. In my eagerness to fix the issue, I made an early misstep: instead of simply cutting the non-working ride crash cymbal TRS cable to check for line continuity, I ended up dismembering the entire plug including the DB-25 pin connector. This mistake set me on a path of troubleshooting that I hadn’t anticipated, and a world of pain.

I scoured the internet for 25-pin pinout diagrams to decipher how the pins were wired, hoping these diagrams would reveal which of the octopus cables belonged to each pin. Unfortunately, I came up empty-handed, as there was no information available for the Donner kit—or even for Medeli, the OEM manufacturer of the kit (or so the internet would have us believe).

With few options left, I had to learn to use my multimeter from scratch. Through many hours of painstakingly wiring and testing each connection, I eventually put together my own version of the pinout. I won’t claim it’s perfect, but if you’re stuck like I was, it might just help you out. And if anyone can point out where the crash choke is, please drop me a line—I’m still on the hunt!

I ran out of steam after getting everything else (I think) working. If you have a better idea or spot something amiss (and let’s face it, you probably do, given that I was a novice in this area), please let me know so I can correct it—and my kit!

Here are a few links that were useful in my journey:

If my attempts have helped you or if you have insights to share, I’d love to hear from you!
