Freaking brilliant. Your mastery of pedal components and their geometry is insane. Keep doing what you do, helping drummers achieve their goals, one hardware upgrade at a time!! 👍👊🤘

*I am so happy with this upgrade, the pedal feels lighter and faster, it glues to my feet and the spring doesn't need to be tight up, which allows me to bury the beater with ease if I want to, without compromising the speed of the pedal. Next will be the drive shaft! Thanks Dennis!*

I bought the geometry upgrade for my eliminator double Pedal and the feeling is awesome. Perfection in combination with the ACD Drive Shaft and the Purple Cam from Pearl

Have had it for a couple of months now and love it! Use it on 2 Iron and 2 Speed cobra single pedals. I bought both regular and heavy versions and have settled for the regular ones but did like the heavy ones as well, since they allowed (almost demanded) the spring tension to be super low when pressing it down, yet still return very quickly due to the increased radius' effect on the springs. Next up I'm planning on trying the beater thingy where the beater comes a little closer to the head, looks like a great invention as well. It's so damn cool you've come up with all these well crafted and amazingly well working things for drummers, not least all the improvements to hardware from the established brands, something they should have thought of themselves but never did. All the best to you Dennis, I'll contact you in the near future about the beater forward placement thing (or whatever it was called, I forgot). Sincerely, Fredrik H.

Sauber Dennis, Wieder mal ein willkommenes Upgrade 👍 Ist bestellt.

i have this upgrade for my Speed Cobra and i must say this upgrade is absolut Amazing . The pedal sticks under your feet.

These work great on my iron cobra 🐍!

Always great to see more drum talk. I love my spring upgrade for my Axis, now I need to get these for my old Pearls! Side note, will we ever see a compression spring (ie Trick and Speed King) style upgrade?

Just put these on my demon drives...and wow. Instantly a different feel. Exactly what you said, they stick under my feet a hell of a lot more.

Wow, this sounds great. I'd like to try one for my Eliminator.

I'd like to see a video of changing out the parts of the Tama Iron Cobra before I attempt to do it myself. And would the drive shaft affect changing out the parts on the slave side of a double pedal?

Looks amazing. It's an $80 upgrade to a double pedal. That's hard to swallow. Great work! I look forward to when these items go into production and become more affordable.

Is there something to upgrade my Taye Double Pedal? Like direct drive links?

Any way to order just the springs? I got the heavy and want to try the regular. Or can you recommend a replacement? Thanks.

I don't see this for Tama on your website.

Just purchased 2. Hyped to try them out on my speed cobra

I'm curious about the acd beaters. When you buy them do they come in pairs or is it just one beater?

Is this available for speed cobras? I didn't see the geometry upgrade anywhere in the upgrades section of the site. Very interested in this part!

Would I still be able to take the spring on and off easily for tear down and setup for the iron cobra ?

Will this fit the pearl p-932 demonator pedal?
