DW 5000TD4 Turbo Bass Drum Pedal, Double Chain
The 5000TD4 is a single bass drum pedal with a concentric cam, the Turbo cam. Concentric means the ratio between your foot's travel and the beater's rotation stays the same from the first millimetre to the last: what your foot gives, the head receives, with no added acceleration along the way.
What sets it apart
- Concentric Turbo cam, constant ratio over the whole stroke
- Even response on the way down and on the way back
- Double chain on sprocket, for steadiness under load
- Fine dynamics available close to the head
- Tri-Pivot clamp with three articulated pads
- Delta hinge with ball bearings
A round cam, and why it is a choice
A round sprocket wraps the chain at the same diameter all the way around. The ratio never varies: at mid-stroke, the beater has covered exactly half its travel. The drummer learns one feel and finds it identical, stroke after stroke.
It is not a slower pedal: it is a pedal whose speed depends entirely on your foot rather than on its geometry. Drummers used to an offset cam sometimes find it soft for the first few minutes — what they feel is the absence of a whip, not a lack of power.
Controlling dynamics near the head
On an offset cam, resistance increases as the beater approaches the head. Playing very softly in that zone then takes restraint, because the mechanism is pushing the other way.
With a constant ratio, a small motion produces a small stroke, and that holds true anywhere in the travel. Styles where the bass drum whispers as much as it hits are well served.
The return matters as much as the stroke
A pedal is not judged only on the way down. After the stroke, the spring has to bring the footboard back under your foot without a jerk, otherwise the next note comes late.
The consistency of the Turbo cam helps here too: the return follows the same law as the downstroke. Combined with the spring rocker mounted on bearings, it gives a return you do not have to second-guess.

Frequently asked questions
- Is the Turbo slower than the Accelerator?
- It adds no acceleration at the end of the stroke, so the speed comes from your foot. Many fast drummers play a round cam with no trouble.
- Can you swap the cam from one pedal to the other?
- It is not designed as an adjustment. The two profiles correspond to two separate models.
- Is it a good pedal for a beginner?
- Yes, and it is often the best place to start: the response is easy to understand and holds no surprises at the end of the stroke.
- Can the spring be adjusted without tools?
- The lock nut is loosened with a drum key, then the tension is set by hand before locking it again.
