Pedals are made with a mallet beater and a drive mechanism. The drive can be used both by chain, belt or carried out directly. Each pedal should simply be playable (smooth), make no disturbing noises and mechanically stable to be built. Small tip: The more features a foot pedal adjustments, the better you can customize them to your own playing technique. In order for the bass drum skin and every stroke of the beater easily "dunk", just a patch (Batter Head Protection - see also under "drum heads") adhere to the skin and at the point where the beater on the bass Drum skin meets.
