Re: cobra coil

Until now, the only way to adjust your beater stroke action was tighten the pedal spring. Sometimes that did the job. More often the action just felt sluggish and heavier. TAMA's latest innovation, the new Cobra Coil simply and easily solves the problem. A special steel spring quickly returns the footboard to its original position so the Iron Cobra feel becomes even more unreal. Even better, the Cobra Coil can be adjusted to different positions on the new 2007 Iron Cobra footboard base plate.
