For the bass drum pedals, there are a variety of adjustments. One of the most important is the side/duel adjusting hoop clamp. This allows you to modify the height of the clamp for your bass drum hoop. Once the adjustment has been made, a quarter turn on the side-hoop clamp is all that is necessary for set up.
Using the allen wrench provided when you purchased the pedal, loosen the set screw on the round knurled nut above the hoop clamp. Adjust the nut to narrow or widen the gap of the hoop clamp for your bass drum. Remember to tighten the set-screw once you dial in the proper height.
The spring tension can be adjusted by loosening the round knurled nut at the base of the spring. Underneath the ear of the base casting, pull down on the spring tension nut and adjust the tension by tightening it or loosening it. After you've dialed it in, keep it there by tightening the knurled nut above the ear.
Another feature is the slotted stroke adjustment. This allows you to adjust the distance of the beater to the drumhead. Just loosen the drum key screw above the spring and set for the desired action.
Delta II pedals feature a weight system that can be modified to suit your playing style. Simply loosen the screw that secures them to the post with a screwdriver and increase or decrease the weights for the desired response.
And finally, there is the beater height. This is the most common adjustment to make. Loosen the drum key screw on the beater hub and raise or lower the beater as necessary. We recommend adjusting only one of these features at a time until you become familiar with the reaction they provide.
