If the snare pad or tom pads are tilting out of position while you’re playing, even though you’ve firmly tightened the respective bolts, the pipe itself may be sliding around. Try firmly retightening the bolts and knobs for the holders that stabilize the center pipe or arms.
* The pads may eventually tilt out of position after you’ve being playing hard for a long time, as the vibrations may loosen the bolts and knobs. If this happens, readjust the pad positions and firmly retighten the bolts for both the pads and the pipes.
