I want to share this because I couldn’t find a solution to this problem online and thought others would like to know about it…
Quite a while ago, we purchased a “Tama Speed Cobra”, single, Bass Drum pedal for my electronic drumset. Earlier this year, the felt pad on its Beater Head (see image on “left” below) had come unglued. In my opinion, this happened because of “poor design”. I had positioned the felt pad so its point was making contact with the rubber, electronic, Bass Drum pad but there must have been enough “angled stress”, while playing, to cause it to slide up and break-away from the glue holding it in place.
I never noticed when the felt pad initially came off. One day, though, I happened to look down and noticed that the hard-plastic Beater Head was now making direct contact with the rubber pad. This was not good. The rubber in that area was now indented and the hardness of the plastic and force of my playing could have damaged the Piezo Sensor inside the pad. It didn’t but it could have.
Although I could have glued the felt pad back on, Sylvia and I thought it would simply detach itself again. So we decided to buy a replacement Beater. We bought the “Tama CB90F” (see image on “right” below).
This replacement Beater is sold just as you see it in this image:
- Balancing Weight,
- Beater Head, etc.
I simply removed the old Beater and installed the new one.
Within a few minutes of playing, I noticed that the Beater Head had pivoted up — forcing its felt pad to no longer make contact with the drum pad. So I rotated the Beater Head back into position and played the pedal while watching the new Beater. Within just a few stokes, I saw the Beater Head turn upwards again. I tightened everything but this continued to happen.
I went online, to see if anyone else had this same problem and how they fixed it. Lots of people had the same issue but I could not find anyone who successfully solved this problem.
I then got out the old Beater and removed the Beater Head. I immediately noticed that the cylinder, which holds the Beater Head is “knurled” — there are “X” patterns etched into it. I then looked at the same portion of the new Beater and saw that it was shiny-smooth. It’s no wonder why the new Beater Head won’t stay in position. There’s nothing for it to grip to.
So I swapped-out the Beater shafts… placing the “old” shaft on the “new” Beater. This solved the problem.
The Beater on the “left” came with my Tama Speed Cobra pedal:
The Beater on the “right” was purchased as a replacement:
